The oceans have been the Earth's most valuable source of food. They have now also become a valuable and versatile source of bioactive compounds. The significance of marine organisms as a natural source of new substances that may contribute to the food sector and the overall health of humans are expanding. This review is an update on the recent studies of functional seafood compounds (chitin and chitosan, pigments from algae, fish lipids and omega-3 fatty acids, essential amino acids and bioactive proteins/peptides, polysaccharides, phenolic compounds, and minerals) focusing on their potential use as nutraceuticals and health benefits.

Nobiletin and tangeretin are major components of polymethoxylated flavones in the peels of citrus fruits such as Citrus reticulata. Because nobiletin and tangeretin have attracted attention due to their beneficial health properties, citrus peel extracts, in which they are concentrated, have the potential to serve as a functional food ingredient to prevent diseases. In this study, a series of toxicological studies on the peel extract of Ponkan cultivar 'Ohta ponkan' (Citrus reticulata Blanco), was conducted. No mutagenic activity was observed in a bacterial reverse mutation test, whereas chromosomal aberrations were induced in an in vitro mammalian chromosomal aberration test. No genotoxicity was observed in an in vivo mammalian micronucleus test. In a 90-day study at daily doses of 54, 180, or 540 mg/kg body weight (bw)/day, hyaline droplet nephropathy, which specifically occurs in adult male rats, was observed in males of 540 mg/kg bw/day group. No other adverse effects were observed in the 90-day study. The no adverse effect level in the 90-day study was considered to be 540 mg/kg bw/day for female rats and less than 540 mg/kg bw/day for male rats., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020.

Functional foods is a very popular term in the social and scientific media; consequently, food producers have invested resources in the development of processed foods that may provide added functional benefits to consumers' well-being. Because of intrinsic regulation and end-of-use purposes in different countries, worldwide meanings and definitions of this term are still unclear. Hence, here we standardize this definition and propose a guideline to attest that some ingredients or foods truly deserve this special designation. Furthermore, focus is directed at the most recent studies and practical guidelines that can be used to develop and test the efficacy of potentially functional foods and ingredients. The most widespread functional ingredients, such as polyunsaturated fatty acids (PUFAs), probiotics/prebiotics/synbiotics, and antioxidants, and their technological means of delivery in food products are described. The review discusses the steps that food companies should take to ensure that their developed food product is truly functional.

Background: Nutraceutical is a term that is a combination of nutrition and pharmaceutical. They are believed to improve physical and mental health and provide therapeutic benefit in disease conditions. Nutraceuticals are claimed to be beneficial in several disease conditions which include cardiovascular disorder, neurodegenerative disorders, metabolic disorders and cancer prevention., Objective: In the current review, we will study the current regulatory framework in some of the major countries of the world by comparing different parameters of these regulations., Findings: Global nutraceutical market is currently expanding at a rapid pace but there are some restraints to the market growth which include poor quality manufacturing and unharmonized regulations leading to trade barriers across the globe. Although there are laws and regulations in place which govern nutraceutical products in different countries, these regulations lack harmonization and differ from country to country. Some of the countries follow stringent regulations, whereas, in some of the countries, well-structured and stern regulations for nutraceuticals are lacking., Conclusion: The development of a well regulated, harmonized and research-driven approach can help boost the confidence of consumers in nutraceutical products in the world thereby driving the nutraceutical market., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

The widespread use of health foods, including supplements, is now common among patients. This is because many health foods are being claimed to be beneficial. If patients use medicines and health foods concurrently, the interaction between the two might lead to adverse events. Additionally, it is reported that pharmacists do not generally care about health food use in their patients, because they also lack sufficient knowledge about health foods. On the contrary, there are some licenses to be a health food advisor in Japan, and the generic name of these licenses is "advisory staff". Pharmacists who have this license are specialists in both medicines and health foods, and thus, they might pay more attention to the concurrent use of medicines and health foods compared to those who do not have the advisory staff license. To address this issue, we conducted a study with an online questionnaire about health food consultation, and 87 pharmacists with advisory staff license participated. Only 36.8% of participants were found to always ask their patients about health food use. However, 92.0% of them had experience of consultation about the simultaneous use of medicines and health foods, and 17.2% of them recognized adverse events by knowing about the concurrent use. Patients who experienced adverse events have used either eicosapentaenoic acid/docosahexaenoic acid supplement with epadel or Ginkgo biloba extract with warfarin. Therefore, an active interview with pharmacists is important to avoid such adverse events in patients.

Dark chocolate is not the most popular chocolate; the higher concentration in antioxidants pays tribute to the increment in bitterness. The caloric density of dark chocolate is potentially lower but has a large variability according to recipes and ingredients. Nevertheless, in the last decade, the interest in dark chocolate as a potential functional food has constantly increased. In this review, we present the nutritional composition, factors influencing the bioavailability, and health outcomes of dark chocolate intake. We have extracted pro- and counter-arguments to illustrate these effects from both experimental and clinical studies in an attempt to solve the dilemma. The antioxidative and anti-inflammatory abilities, the cardiovascular and metabolic effects, and influences on central neural functions were selected to substantiate the main positive consequences. Beside the caloric density, we have included reports placing responsibility on chocolate as a migraine trigger or as an inducer of the gastroesophagial reflux in the negative effects section. Despite an extensive literature review, there are not large enough studies specifically dedicated to dark chocolate that took into consideration possible confounders on the health-related effects. Therefore, a definite answer on our initial question is, currently, not available.

Epidemiological studies are providing strong evidence on beneficial health effects from dietary measures, leading scientists to actively investigate which foods and which specific agents in the diet can prevent diseases. Public health officers and medical experts should collaborate toward the design of disease prevention diets for nutritional intervention. Functional foods are emerging as an instrument for dietary intervention in disease prevention. Functional food products are technologically developed ingredients with specific health benefits. Among promising sources of functional foods and chemopreventive diets of interest, microalgae are gaining worldwide attention, based on their richness in high-value products, including carotenoids, proteins, vitamins, essential amino acids, omega-rich oils and, in general, anti-inflammatory and antioxidant compounds. Beneficial effects of microalgae on human health and/or wellness could in the future be useful in preventing or delaying the onset of cancer and cardiovascular diseases. During the past decades, microalgal biomass was predominately used in the health food market, with more than 75% of the annual microalgal biomass production being employed for the manufacture of powders, tablets, capsules or pastilles. In this review, we report and discuss the present and future role of microalgae as marine sources of functional foods/beverages for human wellbeing, focusing on perspectives in chemoprevention. We dissected this topic by analyzing the different classes of microalgal compounds with health outputs (based on their potential chemoprevention activities), the biodiversity of microalgal species and how to improve their cultivation, exploring the perspective of sustainable food from the sea.

Since "Foods with Function Claims" system was established in 2015, the percentage of people taking health foods and supplements is gradually increasing. The number of people taking both dietary supplements and medicines is also increasing. Therefore, providing information on interaction between dietary supplements and medicines has become increasingly important. We have conducted a study for understanding the awareness of the consumers on the interaction of health foods and supplements with medicines. The ratio of those who do not consult with an informed opinion on the interaction between health foods and supplements with medicines was 76% and 55.2% admitted that they did not experience any side effects as a result of this interaction. In conclusion, the understanding of the interaction between health foods and medication among consumers is still limited and most of them do not consult with specialized physicians. It has been revealed that efforts to expanding the consumers understanding on the risk of interaction between supplements and medicines are necessary. It was suggested that the "Database for guiding the interaction between medicines and health foods" could be a useful tool for providing this type of information.

Cancer patients use health foods (HFs) as complementary and alternative medicine, although the details of their adverse events (AEs) are unclear. We searched three databases [PubMed, "Igaku Chuo Zasshi", and Information System on Safety and Effectiveness for Health Foods website (https://hfnet.nibiohn.go.jp/)] for case reports on AEs related to HF intake in cancer patients published before October 2018. Of the matched reports, 76 studies and 92 patients (31 in Japan, 61 overseas) that met the selection criteria were included in this review. Thus, the severity of AEs and outcomes were not related to either the concomitant use of HF with cancer chemotherapy or cancer stages of patients. AEs caused by HF intake itself accounted for 87%, while drug-HF interaction accounted for 11%. According to the Common Terminology Criteria for Adverse Events (CTCAE) classification, 70% of patients whose grades were identified had severe cases (grades 3 to 5). In Japanese patients, hepatic and respiratory disorders accounted for 52% of the severe cases. Cases were predominantly developed as a result of an allergic mechanism, and mushroom products were mostly used. Overseas, serious cases were induced by products that were already indicated for safety problems. Moreover, notable AEs were recognized, such as hypercalcemia, which were caused by intake of HF containing calcium, vitamin D, and shark cartilage, and bacterial infection caused by probiotic products. Analyzing the details of AEs related to HF intake can help health professionals and cancer patients prevent health hazards.

The antioxidants as polyphenols, especially flavanols present in cocoa, exert a favorable effect on endothelium vasodilation, modulate inflammatory markers, and decrease platelet aggregation, lipid oxidation and insulin resistance. Recent nutritional intervention trials and molecular studies demonstrate that consumption of cocoa, particularly rich in flavanols, is beneficial to promote cardiovascular health. This review describes the cardiovascular effects of chocolate., Competing Interests: The authors declare no competing interests., (© 2018 Garcia et al. Published by IMR press. All rights reserved.)

Current evidence shows that cholesterol management either reduces the likelihood of cardiovascular disease (CVD) or slows down its progression. Hence, it is important that all health professionals make appropriate use of all the available intervention strategies to control risk factors: from dietary improvement and positive lifestyle changes to the use of functional foods, food supplements, and drugs. This review examines the effect of the most frequently occurring cholesterol-lowering substances in functional foods or in supplements across Europe, namely plant sterols and stanols, monacolin K found in red yeast rice, berberine and beta-glucans. We conclude that currently available supplements and functional foods can effectively reduce plasma LDL cholesterol levels by about 5 to 25%, either alone or in combination. Suitable candidates for these products are mainly individuals at low absolute cardiovascular risk at a young age or according to classic algorithms. Of note, despite being freely available for purchase, these products should be used following shared agreement between the physician and the patient ("concordance")., (Copyright © 2018 Elsevier Ltd.

Numerous investigations have been made on plant phenolic compounds and cancer prevention in recent decades. Manuka honey (MH) represents a good source of phenolic compounds such as luteolin, kaempferol, quercetin, gallic acid and syringic acid. The aim of this work was to evaluate the chemopreventive effects of MH on human colon cancer HCT-116 and LoVo cells. Both cells were exposed to different concentrations of MH (0-20 mg mL-1 for HCT-116 cells and 0-50 mg mL-1 for LoVo cells) for 48 h to measure apoptosis and cell cycle arrest as well as apoptosis and cell cycle regulatory gene and protein expression. MH exhibited profound inhibitory effects on cellular growth by reducing the proliferation ability, inducing apoptosis and arresting the cell cycle in a dose-dependent manner. Interestingly, MH treatment in non-malignant cells did not exert any significant toxicity at similar concentrations. The apoptosis event was associated with the increasing expression of p53, cleaved-PARP and caspase-3 and with the activation of both intrinsic (caspase-9) and extrinsic (caspase-8) apoptotic pathways. MH induced cell cycle arrest in the S phase in HCT-116 cells, and simultaneously, in LoVo cells, it occurred in the G2/M phase through the modulation of cell cycle regulator genes (cyclin D1, cyclin E, CDK2, CDK4, p21, p27 and Rb). The expression of p-Akt was suppressed while the expression of p-p38MAPK, p-Erk1/2 and endoplasmic stress markers (ATF6 and XBP1) was increased for apoptosis induction. Overall, these findings indicate that MH could be a promising preventive or curative food therapy for colon cancer.

Despite its high content of phenolic compounds, the chemopreventive activity of Manuka honey (MH) is still elusive. The aim of the present work was to evaluate the effects of MH on oxidative stress, antioxidant enzymes, cellular metabolism and the metastatic ability in HCT-116 and LoVo cells, paying particular attention to the molecular mechanisms involved. We observed a strong induction of oxidative stress after MH treatment since it augmented the accumulation of reactive oxygen species and increased the damage to proteins, lipids and DNA. Furthermore, MH suppressed the Nrf2-dependent antioxidant enzyme expression (superoxide dismutase (SOD), catalase and heme oxygenase-1) and the activity of SOD, catalase, glutathione peroxidase and glutathione reductase. Cell metabolisms were markedly disrupted after MH treatment. It decreased maximal oxygen consumption and spare respiratory capacity, which could reduce the mitochondrial function that is correlated with cell survival potential. Simultaneously, MH decreased the extracellular acidification rate (glycolysis) of HCT-116 and LoVo cells. Furthermore, MH suppressed the p-AMPK/AMPK, PGC1α and SIRT1 activation, involved in the survival of HCT-116 and LoVo cells under metabolic stress conditions. Dose-dependently, MH reduced the migration and invasion (MMP-2 and MMP-9) ability, and concurrently regulated EMT-related markers (E cadherin, N cadherin, and β-catenin) in both cell types. The above findings indicate that MH induces HCT-116 and LoVo cell death partly by enhancing oxidative stress, as well as by regulating the energy metabolism in both aerobic and anaerobic pathways and suppressing the metastatic ability.

Steady-fiber granule (SFG) is a functional food mixture that is composed of four major ingredients, resistant maltodextrin, white kidney bean (Phaseolus vulgaris) extract, mulberry leaf (Morus alba L.) extract, and niacin-bound chromium complex. This study focused on determining the safety of SFG. Genotoxicity and 28-day oral toxicity were evaluated. SFG did not induce mutagenicity in the bacterial reverse mutation assay using five Salmonella typhimurium strains (TA98, TA100, TA102, TA1535, and TA1537) in the presence or absence of metabolic activation (S9 system). SFG also did not induce clastogenic effects in Chinese hamster ovary cells with or without S9 treatment. Similarly, SFG did not induce genotoxicity in a micronucleus test conducted with mice. A dose-dependent 28-day oral toxicity assessment of SFG for rats revealed no significant effects on mortality, body weight, selected organ weights, and behavior. Evaluations of hematology, clinical biochemistry, and histopathology showed no adverse effects in rats treated with SFG. These results suggest that SFG has no significant mutagenic or toxic properties, and the no observed adverse effect level of SFG was defined as at least 5000 mg/kg/day orally for 28 days for male and female rats., (Copyright © 2017.

The aim of this study was the evaluation of hypoglycemic action of functional food ingredient (FFI) - a polyphenol food matrix in 3-month in vivo experiment with the use of fat male mice C57BL/6. The food matrix was produced by means of incubation of bilberry leaves extract (2% solution, pH 3.6) with buckwheat flour in ratio 1:50 during 45 min at 25 °C. The polyphenol content in experimental batch of matrix was 26.6±0.5 mg-equivalent of gallic acid per 1 g of flour. The experiment was conducted with the use of 46 male mice C57Bl/6c. Blood glucose level was estimated before starting the feeding experiment. An oral fasting glucose tolerance test (GTT) was also conducted, the area under the curve (AUC) was calculated. The animals were randomly divided into 4 groups (according to the body weight, glucose level and AUC): control group K1, fed with standard semisynthetic diet, control group K2 ( n =10) and experimental groups G3 and G4 ( n =13). The symptoms of type 2 diabetes in groups K2, G3 and G4 were modeled with the use of high-fat high-carbohydrate diet (HFHC diet, 30% fat, 20% sucrose). FFI was included into the diet of animals of experimental groups G3 and G4 in doses 2.5 and 5 g per 100 g of ration, respectively. The GTT test was repeated on the 40th and 82nd days of experiment. On the 15th, 54th and 91st days the insulin resistance test (IRT) was conducted. The consumption of HFHC diet by K2 group animals resulted in development of obesity in these animals to the week 11, which was characterized by increase in the body weight gain (37.1±4.9%) in comparison with control group K1 animals (23.4±2.2%). The introduction of FFI into animal's diet decreased significantly body weight gain of these animals in comparison with K2 group. On the week 8, the significant increase in blood glucose level of animals fed with HFHC diet was found (K2 - 8.2±0.3, G3 - 8.1±0.3, G4 - 8.5±0.3 mmol/L), in comparison with control group K1 (7.1±0.3 mmol/L). On the 91st day of experiment this difference remained significant only for group K2 (9.3±0.6 against K1 group - 7.7±0.3 mmol/L), what shows the beneficial hypoglycemic action of the FFI in both doses (for G3 group - 8.5±0.2, for G4 - 8.4±0.3 mmol/L). On the week 8 the disorder in glucose tolerance was found in animals of group K2, what is one of type 2 diabetes symptoms. The introduction of FFI in a dose 2.5 g/100 g into group G3 diet inhibited the development of these disease symptoms. The introduction of FFI in a higher dose (5 g/100 g of a diet) to a certain extent inhibited the development of insulin resistance. There was no effect of FFI, introduced into animal's diet, on cognitive functions and short-term and long-term memory., Competing Interests: The authors declare no overt and potential conflict of interest related to the publication of this article., (Copyright© GEOTAR-Media Publishing Group.)

In recent years, consumer interest in health and health foods (e.g., dietary supplements) has increased, and the types of and market for health foods have also expanded rapidly. The safety of health foods is a significant concern in many countries. Numerous adverse events associated with the consumption of health foods have been reported. There are cases that have resulted in serious liver failure, renal failure, and death in other countries. These products may contain undeclared medical ingredients and toxic chemical compounds that are illegally and intentionally added or contain natural plant toxins. Products containing high levels of heavy metals have also been reported to cause such adverse events. Some products remain on the market, even after regulatory agencies alert consumers and issue warnings to their sellers. Moreover, because people can buy health foods from sources overseas via the Internet, adverse effects associated with the use of such products remain a concern. Two cases of adverse events were reported in Japanese individuals who purchased "OxyElite Pro" products imported privately. They are advertised as weight-loss and muscle-building products and have been associated with many cases of liver failure and hepatitis in the USA. In this paper, regulatory systems and adverse events associated with the use of health foods in other countries are discussed.

Along with an increase in self-care and self-medication practices, the use of health foods as primary and secondary methods of disease prevention has increased. Consumers are aware only of the health benefits of dietary ingredients, although the potential risks associated with most ingredients are unknown. Adverse events associated with the use of health foods have been reported, and in some cases they were due to inappropriate use such as the concomitant use of several health foods or health foods and drugs. It is important that healthcare professionals, especially pharmacists, provide reliable, evidence-based information to ensure the safe and appropriate use of dietary supplements by their patients. Thus, we constructed an online database, the "Health Foods Network (HFNet)" that compiles reports on the safety and effectiveness of health foods and their ingredients. It serves to disseminate information based on scientific research not only in Japan but also worldwide. This article provides an overview of the HFNet. Additionally, findings from our recent survey and educational interventions among college students are discussed. We hope that this article will be helpful for pharmacists and other healthcare professionals who provide consultations on the use of health foods.

Although many people (and patients) in Japan currently consume health foods such as supplements, few have proper knowledge of their usefulness and safety. In December 2015, the Food Safety Commission of Japan issued a report and 19 messages mainly on the safety of health foods to disseminate appropriate knowledge to consumers. The report divided health food risks into three categories: 1) risks as food (e.g., increased lung cancer risk in smokers consuming excess β-carotenoid); 2) risks as health foods (e.g., short consumption history, drug contamination, poor quality of active ingredients, and interactions with drugs); and 3) risks due to a lack of adequate scientific information on health foods. The risk of insulin autoimmune syndrome caused by α-lipoic acid is relatively high among Japanese individuals because its onset is associated with HLA-DRB1*04:06, an HLA allele occurring frequently in East Asian populations. As for health food-drug interactions, an important pharmacokinetic interaction between drugs and St. John's Wort was described from several viewpoints: different effects on drugs within the same class (depending on the metabolic pathway); interindividual differences in its effects; importance of considering active metabolite involvement; and time course of interaction. An example of an interaction affecting drug efficacy was also introduced. Because the Japanese government now promotes a health-supportive pharmacy program in which pharmacies have a role in supporting the health of local patients/consumers, pharmacists are expected to acquire more scientific information on health foods, evaluate their evidence levels, and provide that information in plain language to patients/consumers.

We have been studying the way advertisements for medicines have been monitored by the Health, Labour and Welfare Sciences Research Grants. In the last fiscal year, we identified products that were being advertised to general consumers, such as OTC drugs and designated quasi-drugs, and made recommendations to the Ministry of Health, Labour and Welfare on the methods of advertisement. Members of our research group, including physicians, pharmacists, and consumers, pointed out that advertisements for so-called health foods and foods with functional claims were much more unregulated than those for drugs, including OTC drugs. Thus, this fiscal year, we decided to focus on health foods. Advertisements for health foods are regulated by the Health Promotion Act and the Act against Unjustifiable Premiums and Misleading Representations; moreover, in many cases, cautions are issued by the Consumer Affairs Agency or prefectures. Several studies also reported health damage in patients who, because of their belief in advertisements, intentionally discontinued treatment or missed the opportunity to receive appropriate medical treatment. Here, we report inappropriate advertisements for health foods that may cause health hazards.

Evidence suggests a protective role for several nutrients and foods in the maintenance of skin function. Nevertheless, all the requests for authorization to use health claims under Article 13(5) in the framework of maintenance of skin function presented to the European Food Safety Authority (EFSA) have received a negative opinion. Reasons for such failures are mainly due to an insufficient substantiation of the claimed effects, including the choice of inappropriate outcome variables (OVs) and methods of measurement (MMs). The present paper reports the results of an investigation aimed at collecting, collating and critically analyzing the information with relation to claimed effects (CEs), OVs and MMs related to skin health compliance with Regulation 1924/2006. CEs, OVs and MMs were collected from both the EFSA Guidance document and from the authorization requests of health claims under Article 13(5). The critical analysis of OVs and MMs was based on a literature review, and was aimed at defining their appropriateness (alone or in combination with others) in the context of a specific CE. The results highlight the importance of an adequate choice of OVs and MMs for an effective substantiation of the claims., Competing Interests: The authors declare no conflict of interest.

Significant reductions in insulin resistance (IR) can be achieved by either calorie restriction or by the increase of lean mass. However, calorie restriction usually results in significant loss of lean mass. A 6-week randomized controlled feeding trial was conducted to determine if a calorie-restricted, high-protein diet (~125 g protein/day consumed evenly throughout the day) using novel functional foods would be more successful for reducing IR in comparison to a conventional diet (~80 g protein/day) with a similar level of calorie restriction. Healthy adults (age 20-75 years; body mass index, 20-42 kg/m²) with raised triglyceride/high-density lipoprotein ratios were randomly assigned to the control group (CON: test foods prepared using gluten-free commercial pasta and cereal) or to the high-protein group (HPR: test foods prepared using novel high-protein pasta and cereal both rich in wheat gluten). Mean weight loss did not differ between groups (-2.7 ± 2.6 and -3.2 ± 3.0 kg for CON ( n = 11) and HPR ( n = 10) respectively, p = 0.801); however, the 6-week change in fat-free mass (FFM) differed significantly between groups (-0.5 ± 1.5 and +1.5 ± 3.8 kg for CON and HPR respectively, p = 0.008). IR improved in HPR vs. CON participants (homeostasis model assessment-estimated insulin resistance [HOMAIR] change: -1.7 ± 1.4 and -0.7 ± 0.7 respectively; p = 0.020). The change in HOMA-IR was related to the change in FFM among participants ( r = -0.511, p = 0.021). Thus, a high-protein diet using novel functional foods combined with modest calorie restriction was 140% more effective for reducing HOMA-IR in healthy adults compared to a lower protein, standard diet with an equal level of calorie restriction., Competing Interests: C.S.J. and J.R.K. declare no conflict of interest.

Background: A meta-analysis was conducted to summarize the evidence from prospective cohort and case-control studies regarding the association between coffee intake and biliary tract cancer (BTC) and liver cancer risk., Methods: Eligible studies were identified by searches of PubMed and EMBASE databases from the earliest available online indexing year to March 2017. The dose-response relationship was assessed by a restricted cubic spline model and multivariate random-effect meta-regression. A stratified and subgroup analysis by smoking status and hepatitis was performed to identify potential confounding factors., Results: We identified five studies on BTC risk and 13 on liver cancer risk eligible for meta-analysis. A linear dose-response meta-analysis did not show a significant association between coffee consumption and BTC risk. However, there was evidence of inverse correlation between coffee consumption and liver cancer risk. The association was consistent throughout the various potential confounding factors explored including smoking status, hepatitis, etc. Increasing coffee consumption by one cup per day was associated with a 15% reduction in liver cancer risk (RR 0.85; 95% CI 0.82 to 0.88)., Conclusions: The findings suggest that increased coffee consumption is associated with decreased risk of liver cancer, but not BTC.

Background and Aims: The high number of negative opinions from the European Food Safety Authority (EFSA) to the requests for authorization of health claims is largely due to the design of human intervention studies, including the inappropriate choice of outcome variables (OVs) and of their methods of measurement (MMs). The present manuscript reports the results of an investigation aimed to collect, collate and critically analyse the information in relation to claimed effects, OVs and MMs, in the context of protection against oxidative damage and cardiovascular health compliant with Regulation 1924/2006., Methods and Results: Claimed effects, OVs and the related MMs were collected from EFSA Guidance documents and applications for authorization of health claims under Articles 13.5 and 14. The OVs and their MMs were evaluated only if the claimed effect was sufficiently defined and was considered beneficial by EFSA. The collection, collation and critical analysis of the relevant scientific literature consisted in the definition of the keywords, the PubMed search strategies and the creation of databases of references. The critical analysis of the OVs and their MMs was performed on the basis of the literature review and was aimed at defining the appropriateness of OVs and MMs in the context of the specific claimed effects., Conclusions: The information provided in this document could serve to EFSA for the development of further guidance on the scientific requirements for health claims, as well as to the stakeholders for the proper design of human intervention studies aimed to substantiate such health claims., (Copyright © 2017 The Italian Society of Diabetology, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition, and the Department of Clinical Medicine and Surgery, Federico II University.

Despite their nutritional value, population-level nut consumption remains low. Studies suggest that individuals would eat more nuts on their doctor's advice, making health professionals potentially important for promoting nut consumption. This cross-sectional study aimed to examine the perceptions and knowledge of nuts and the predictors of nut promotion among health professionals in New Zealand. Dietitians, general practitioners (GPs), and practice nurses were identified from the Electoral Roll and invited to complete a questionnaire (n = 318, 292, and 149 respondents respectively). Over one-fifth of GPs and practice nurses believed that eating nuts could increase blood cholesterol concentrations and cause weight gain. The most common perceptions overall were that nuts are healthy; high in protein, fat, and calories; and are satiating. Nut consumption was recommended for reasons relating to these perceptions and because of nuts' selenium content. Conversely, reasons for suggesting the consumption of fewer nuts included that they were high in calories and fat, would cause weight gain, and concerns regarding allergies and cost. All groups of health professionals were more likely to promote nut consumption if they perceived nuts to reduce the risk of diabetes (all p ≤ 0.034). Education could improve health professionals' knowledge regarding the effects of nut consumption on blood cholesterol and body weight, alongside other health benefits, which should improve the advice given to patients and may thereby increase nut consumption.

Background: In soybean, at least 16 seed proteins have been identified as causing allergenic reactions in sensitive individuals. As a soybean genebank accession low in the immunodominant protein P34 (Gly m Bd 30K) has recently been found, introgression of the low-P34 trait into adapted soybean germplasm has been attempted in order to improve the safety of food products containing soybean protein. Therefore, marker-assisted selection and proteomics were applied to identify and characterize low-P34 soybeans., Results: In low-P34 lines selected from a cross-population, concentrations of the P34 protein as identified with a polyclonal antibody were reduced by 50-70% as compared to P34-containing controls. Using 2D electrophoresis and immunoblotting, the reduction of P34 protein was verified in low-P34 lines. This result was confirmed by liquid chromatographic-tandem mass spectrometric analysis, which revealed either a reduction or complete absence of the authentic P34 protein as suggested from presence or absence of a unique peptide useful for discriminating between conventional and low-P34 lines., Conclusion: Marker-assisted selection proved useful for identifying low-P34 soybean lines for the development of hypoallergenic soy foods. The status of the P34 protein in low-P34 lines needs further characterization. In addition, the food safety relevance of low-P34 soybeans should be tested in clinical studies. © 2016 Society of Chemical Industry., (© 2016 Society of Chemical Industry.)

The basis for gluten-free diet is often gluten-free bread, which is usually characterized by a low-nutritional value, and lacks any pro-health properties. Only after an introduction of gluten-free raw materials, containing high level of bioactive compounds it would be possible to obtain the product with a pro-health potential. The aim of the study was to analyze the content of bioactive compounds (total phenolic content, phenolic acids, flavonoids, flavonols, anthocyanins and carotenoids) in gluten-free bread prepared with 5% addition of freeze-dried red and purple potatoes as well as to assess their antioxidant potential. Summarizing, among the analyzed gluten-free breads with an addition of freeze-dried red and purple potatoes, the best results could be obtained by using variety Magenta Love (red potato), which provided the highest levels of phenolic compounds and carotenoids and also antioxidant and antiradical activity.

Health claims potentially represent an opportunity for firms to engage in product differentiation and thereby induce investment into R&D and innovation in the food sector. The Nutrition and Health Claims Regulation (EC) No. 1924/2006 (NHCR) aims at protecting and promoting innovation as one of its objectives. However, existing studies indicate that this regulation may create several challenges for innovation in the food sector. To this end, we review the challenges related to the NHCR (Article 13.1) and its impact on innovation. Extant literature suggests that companies face challenges related to changing list of ingredients, missing transparency, wording of claims, limited financial resources, limited R&D resources, switching product categories and abandoning the functional foods sector. Moreover, current studies imply that so far the NHCR (in specific Article 13.1) does not seem to encourage innovation in the EU food sector.

Literature suggests that despite its positive aim of promoting innovation, the Nutrition and Health Claims Regulation (EC) No. 1924/2006 (NHCR) may bring along several compliance challenges, which might affect innovation in the EU food sector. This study investigates the challenges faced by companies to comply with the NHCR (specifically Article 13.1) and their impact on innovation. To this end, we conducted an online survey with 105 companies involved in the EU food sector. Results indicate that companies perceive wording of claims, missing transparency and limited financial resources as major challenges to comply with the NHCR (Article 13.1). Companies reported not to have increased their R&D expenditure or innovation activities after the NHCR (Article 13.1) was implemented. Thus, this study highlights specific compliance challenges related to the NHCR (Article 13.1) and indicates that currently, the regulation does not seem to have fostered innovation in the EU food sector.

Citrus juices such as 100% orange (OJ) and grapefruit juice (GJ) are commonly consumed throughout the world. This review examines the contributions of OJ and GJ to nutrient intake, diet quality, and fruit intake, and supports citrus juices as nutrient-dense beverages. This review also explores the research examining associations between OJ and GJ intake and anthropometric measures. Citrus juices are excellent sources of vitamin C and contribute other key nutrients such as potassium, folate, magnesium, and vitamin A. OJ intake has been associated with better diet quality in children and adults. OJ intake has not been associated with adverse effects on weight or other body measures in observational studies in children and adults. In adults, some observational studies report more favorable body mass index or body measure parameters in OJ consumers compared to nonconsumers. Intervention studies in adults report no negative impacts of OJ or GJ consumption on anthropometric measures, although these measures were typically not the primary outcomes examined in the studies. Moderate consumption of citrus juices may provide meaningful nutritional and dietary benefits and do not appear to negatively impact body weight, body composition, or other anthropometric measures in children and adults.

One hundred percent fruit juice (FJ) contains bioactive compounds with antioxidant activity. As such, this fruit form has the potential to improve antioxidant status and mediate outcomes influenced by redox status. A systematic review of the literature published between 1995 and 2013 was conducted using PubMed database to evaluate associations between intake of 100% FJ and markers of antioxidant/oxidant status and blood lipid levels in healthy, free-living adults ≥18 years. Data extraction and analysis was conducted according to the Academy of Nutrition and Dietetics Evidence Analysis Process. Limited evidence from ten clinical trials meeting inclusion/exclusion criteria suggests potential improvements in a variety of antioxidant or oxidants biomarkers postconsumption of 100% FJ. Weak evidence from five studies suggests that one or more blood lipid measures may be positively influenced by consumption of 100% FJ. Heterogeneity in study methodology including biomarkers, 100% FJ type, dosage, and intervention duration precludes the ability to make evidence-based recommendations regarding a specific dose-duration-juice effect. Key characteristics in study designs were identified which must either be controlled or statistically adjusted for in future investigations in order to obtain a more accurate understanding of the complex relationship between metabolic outcomes and consumption of 100% FJ in context of a healthy dietary pattern.

Adverse events associated with health food use appear to be quite common. Nevertheless, even though severe adverse events should be reported to the Japanese government via public health centers, the number of cases reported is relatively small. To clarify this discrepancy and to understand how consumers and physicians act when they or their patients develop adverse events due to health food use, we conducted an internet questionnaire with consumers (preliminary survey: n=44,649; full survey: n=3,000), physicians (n=500), and pharmacists (n=500). During 2016, 17% of consumers who used health foods developed adverse events. However, only 11% of them reported their adverse events to public health centers. Most physicians and pharmacists did not report these cases to public health centers because they were unable to establish a clear cause-and-effect relationship. It is important to encourage not only consumers, but also physicians and pharmacists to report adverse events to public health centers.

"Food with Function Claims" was established on April 1 st 2015. In the present study, we conducted internet surveillance to examine recognition of "Food with Function Claims" among consumers (n=2,060), physicians (n=515), and pharmacists (n=515). The ratio of recognition of "Food with Function Claims" was 81% among consumers, 93% among physicians, and 98% among pharmacists. However, only 16% of consumers, 23% of physicians, and 44% of pharmacists correctly understood the characteristics of "Food with Function Claims". Only 12% of consumers were using or have used "Food with Function Claims". Among "Food with Function Claims" users, 26% checked the information about "Food with Function Claims" on the website of the Consumer Affairs Agency, Government of Japan. Some of them used "Food with Function Claims" for treatment their diseases. In addition, some of them used "Food with Function Claims" and medicines concomitantly without consulting their physicians or pharmacists. Consequently, only 8% of physicians and pharmacists were asked about dietary supplement use by their patients, and 2% of physicians and pharmacists had consultations with their patients on adverse events associated with using "Food with Function Claims".

Se and green tea have been shown in epidemiological, observational and preclinical studies to be inversely related to the risk of developing colorectal cancer (CRC). However, there are limited studies to evaluate their regulatory effects on genes/proteins that relate to CRC oncogenesis in human subjects, such as selenoproteins, WNT signalling pathway, inflammation and methylation. This study examined the effects of supplementation of Se using Brazil nuts and green tea extract (GTE) capsules, alone and in combination, on targeted biomarkers. In total, thirty-two volunteers (>50 years of age) with plasma Se≤1·36 µmol/l were randomised to one of three treatment groups: nine to Se (approximately 48 µg/d) as six Brazil nuts, eleven to four GTE capsules (800 mg (-)-epigallocatechin-3-gallate) and twelve to a combination of Brazil nuts and GTE. Blood and rectal biopsies were obtained before and after each intervention. Plasma Se levels, rectal selenoprotein P (SePP) and β-catenin mRNA increased significantly in subjects consuming Brazil nuts alone or in combination, whereas rectal DNA methyltransferase (DNMT1) and NF-κB mRNA were reduced significantly in subjects consuming GTE alone or in combination. None of the interventions significantly affected rectal acetylated histone H3 or Ki-67 expression at the protein level or plasma C-reactive protein. Effects of the combination of Brazil nuts and GTE did not differ from what would be expected from either agent alone. In conclusion, supplementation of Brazil nuts and/or GTE regulates targeted biomarkers related to CRC oncogenesis, specifically genes associated with selenoproteins (SePP), WNT signalling (β-catenin), inflammation (NF-κB) and methylation (DNMT1). Their combination does not appear to provide additional effects compared with either agent alone.

Background: The consumption of sweet beverages has been associated with greater risk of type 2 diabetes and obesity, which may be involved in the development of pancreatic cancer. Therefore, it has been hypothesized that sweet beverages may increase pancreatic cancer risk as well., Objective: We examined the association between sweet-beverage consumption (including total, sugar-sweetened, and artificially sweetened soft drink and juice and nectar consumption) and pancreatic cancer risk., Design: The study was conducted within the European Prospective Investigation into Cancer and Nutrition cohort. A total of 477,199 participants (70.2% women) with a mean age of 51 y at baseline were included, and 865 exocrine pancreatic cancers were diagnosed after a median follow-up of 11.60 y (IQR: 10.10-12.60 y). Sweet-beverage consumption was assessed with the use of validated dietary questionnaires at baseline. HRs and 95% CIs were obtained with the use of multivariable Cox regression models that were stratified by age, sex, and center and adjusted for educational level, physical activity, smoking status, and alcohol consumption. Associations with total soft-drink consumption were adjusted for juice and nectar consumption and vice versa., Results: Total soft-drink consumption (HR per 100 g/d: 1.03; 95% CI: 0.99, 1.07), sugar-sweetened soft-drink consumption (HR per 100 g/d: 1.02; 95% CI: 0.97, 1.08), and artificially sweetened soft-drink consumption (HR per 100 g/d: 1.04; 95% CI: 0.98, 1.10) were not associated with pancreatic cancer risk. Juice and nectar consumption was inversely associated with pancreatic cancer risk (HR per 100 g/d: 0.91; 95% CI: 0.84, 0.99); this association remained statistically significant after adjustment for body size, type 2 diabetes, and energy intake., Conclusions: Soft-drink consumption does not seem to be associated with pancreatic cancer risk. Juice and nectar consumption might be associated with a modest decreased pancreatic cancer risk. Additional studies with specific information on juice and nectar subtypes are warranted to clarify these results., (© 2016 American Society for Nutrition.)

There is rising evidence of patients' use of alternative and complementary medicine. The percentage of the U.S. population who used at least one dietary supplement increased from 42% in 1988-1994 to 53% in 2003-2006. We present a case of an Asian female in her 40s, with no previous psychiatric illness, who presented to the emergency room following a brief psychotic episode, during which she self-amputated the tips of her fingers, after using multivitamins and herbal supplements including ginseng, gui yuan rou (Chinese herb), astaxanthin, goji (Chinese fruit), selenium, saw palmetto, grape seed extract, citrus bioflavanoid, lutein (zeaxantin), resvexatrol, sun chlorella, spirulina powder, phytoceramides, phytoestrogen, glucosatrin, bromelain plus, and American bee pollen. Comprehensive laboratory workup, drug screening, and diagnostic imaging were negative. Vital signs were stable. Other than the amputated finger tips, the remainder of her physical examination was unremarkable. Her mental status improved significantly after treatment with risperidone 1 mg twice daily, during a five-day psychiatric hospitalization. This case draws attention to the fact that supplements have the potential of producing frank psychosis and require close monitoring and study by physicians.

One of the most recent food trends is the quest for products that provide 'sustained energy'; a term that is garnering considerable attention within the marketplace. Often, 'sustained energy' health claims are based on a food's post-prandial glycaemic response. However, are generalised health claims regarding 'sustained energy' valid when only supported by glycaemic response data? Without context, the short answer is: probably not. Health claims that link sustained energy to a glycaemic response, or any other attribute of a food or diet, require context to ensure that the public correctly interprets and experiences the claimed effect and is not misled in their quest for healthy foods that impose the desired physiological benefit., (© 2016 The British Dietetic Association Ltd.)

Yacon (Smallanthus sonchifolius), a perennial plant of the family Asteraceae native to the Andean regions of South America, is an abundant source of fructooligosaccharides (FOS). This comprehensive review of the literature addressed the role of yacon supplementation in promoting health and reducing the risk of chronic diseases. According to several preclinical and clinical trials, FOS intake favors the growth of health-promoting bacteria while reducing pathogenic bacteria populations. Moreover, the endproducts of FOS fermentation by the intestinal microbiota, short chain fatty acids (SCFA), act as substrates or signaling molecules in the regulation of the immune response, glucose homeostasis and lipid metabolism. As a result, glycemic levels, body weight and colon cancer risk can be reduced. Based on these findings, most studies reviewed concluded that due to their functional properties, yacon roots may be effectively used as a dietary supplement to prevent and treat chronic diseases.

Red yeast rice (RYR), the fermentation product of mold Monascus purpureus has been an integral part of Oriental food and traditional Chinese medicine, long before the discovery of their medicinal roles. With the identification of bioactive components as polyketide pigments (statins), and unsaturated fatty acids, RYR has gained a nutraceutical status. Hypercholesterolemic effect of this fermented compound has been validated and monacolin K has been recognized as the pivotal component in cholesterol alleviation. Functional similarity with commercial drug lovastatin sans the side effects has catapulted its popularity in other parts of the world as well. Apart from the hypotensive role, ameliorative benefits of RYR as anti-inflammatory, antidiabetic, anticancer and osteogenic agent have emerged, fueling intense research on it. Mechanistic studies have revealed their interaction with functional agents like coenzyme Q10, astaxanthin, vitamin D, folic acid, policosanol, and berberine. On the other hand, concurrence of mycotoxin citrinin and variable content of statin has marred its integration in mainstream medication. In this disputable scenario, evaluation of the scopes and lacunae to overcome seems to contribute to an eminent area of healthcare. Red yeast rice (RYR), the rice-based fermentation product of mold Monascus purpureus is a functional food. Its bioactive component monacolin K acts like synthetic drug lovastatin, without the severe side effects of the latter. RYR has been validated to lower cholesterol, control high blood pressure; confer anti-flammation, hypoglycaemic, anticancer and osteogenic properties. However, dose inconsistency and co-occurrence of toxin citrinin hampers its dietary supplementation prospect. Further research might facilitate development of RYR as a nutraceutical.

The consumption of alcohol is often accompanied by other foods, such as fruits and vegetables. This study is aimed to investigate the effects of 20 selected fruits on ethanol metabolism to find out their potential health benefits and harmful impacts. The effects of the fruits on ethanol metabolism were characterized by the concentrations of ethanol and acetaldehyde in blood, as well as activities of alcohol dehydrogenase and acetaldehyde dehydrogenase in liver of mice. Furthermore, potential health benefits and harmful impacts of the fruits were evaluated by biochemical parameters including aspartate transaminase (AST), alanine transferase (ALT), malondialdehyde, and superoxide dismutase. Generally, effects of these fruits on ethanol metabolism were very different. Some fruits (such as Citrus limon (yellow), Averrhoa carambola, Pyrus spp., and Syzygium samarangense) could decrease the concentration of ethanol in blood. In addition, several fruits (such as Cucumis melo) showed hepatoprotective effects by significantly decreasing AST or ALT level in blood, while some fruits (such as Averrhoa carambola) showed adverse effects. The results suggested that the consumption of alcohol should not be accompanied by some fruits, and several fruits could be developed as functional foods for the prevention and treatment of hangover and alcohol use disorder.

Ferritin-iron is currently considered as one of the most promising iron forms to prevent iron deficiency anaemia. We found that the cultivation of soybean seeds in a solution of ferrous sulfate results in material with extremely high iron content - 560.6 mg Fe/100 g of dry matter, while ferritin iron content was 420.5 mg/100 g dry matter. To assess the potential adverse effects of a preparation containing such a high concentration of iron, male and female Wistar rats were exposed via diet to 10, 30, 60 g soybean sprouts powder/kg feed for 90 days. There were no differences in final body weight and mean food consumption between controls and rats administered sprouts. No statistically significant differences in haematology and clinical chemistry parameters were found between controls and treated rats. Microscopic examination of 22 tissues did not reveal any pathology due to soybean sprouts intake. Long term administration of the test material did not cause oxidative damage to DNA and protein in the liver as evidenced by the unchanged basal levels of DNA damage as well as carbonyl groups content. Lipid peroxidation was slightly increased only in females. The activity of several antioxidant enzymes: superoxide dismutase, glutathione peroxidase and glutathione S-transferase was increased, which substantially enhanced the antioxidant status in the liver from the rats treated with soybean sprouts. Hence, the material tested can be recommended as a component of food supplements for individuals with iron deficiency anaemia and inflammatory bowel diseases.

Functional foods have become increasingly popular with consumers anxious to mitigate the effects of an unhealthy lifestyle or aging. In spite of attractive health claims, these products do not have legal or regulatory status in most countries and are regulated through their health claims. Regulation of functional foods by health claims does not address health risks and adverse effects of these products. In this essay regulatory aspects of functional foods are reviewed along with adverse effects published in the peer-reviewed literature. We detail why the lack of an internationally accepted definition of functional foods places consumers at risk of adverse outcomes. Our review will assist regulatory agencies, manufacturers and consumer groups to assess the benefits and reduce the risks associated with these products.

Background: More than one-half of coronary artery disease (CAD) patients have low HDL cholesterol despite having well-managed LDL cholesterol. Almond supplementation has not been shown to elevate circulating HDL cholesterol concentrations in clinical trials, perhaps because the baseline HDL cholesterol of trial subjects was not low., Objective: This clinical trial was designed to test the effect of almond supplementation on low HDL cholesterol in CAD patients., Methods: A total of 150 CAD patients (50 per group), with serum LDL cholesterol ≤100 mg/dL and HDL cholesterol ≤40 mg/dL in men and ≤50 mg/dL in women, were recruited from the Aga Khan University Hospital. After recording vital signs and completing a dietary and physical activity questionnaire, patients were randomly assigned to 1 of the following 3 groups: the no-intervention group (NI), the Pakistani almonds group (PA), and the American almonds group (AA). The respective almond varieties (10 g/d) were given to patients with instructions to soak them overnight, remove the skin, and eat them before breakfast. Blood samples for lipid profiling, body weight, and blood pressure were collected, and assessment of dietary patterns was done at baseline, week 6, and week 12., Results: Almonds significantly increased HDL cholesterol. At weeks 6 and 12, HDL cholesterol was 12-14% and 14-16% higher, respectively, in the PA and AA than their respective baselines. In line with previous reports, serum concentrations of total cholesterol, triglycerides, LDL cholesterol, and VLDL cholesterol; total-to-HDL and LDL-to-HDL cholesterol ratios, and the atherogenic index were reduced in both the PA and AA at weeks 6 and 12 compared with baseline (P < 0.05). Effects on serum lipids did not differ between the 2 almond groups. Dietary patterns, body weight, and blood pressure did not change in any of the 3 groups during the trial., Conclusion: A low dose of almonds (10 g/d) consumed before breakfast can increase HDL cholesterol, in addition to improving other markers of abnormal lipid metabolism in CAD patients with low initial HDL cholesterol. This trial was registered at the Australian New Zealand Clinical Trial Registry as ACTRN12614000036617., (© 2015 American Society for Nutrition.)

Inflammation is a normal acute response of the immune system to pathogens and tissue injury. However, chronic inflammation is known to play a significant role in the pathophysiology of numerous chronic diseases, such as cardiovascular disease, type 2 diabetes mellitus, and cancer. Thus, the impact of dietary factors on inflammation may provide key insight into mitigating chronic disease risk. Eggs are recognized as a functional food that contain a variety of bioactive compounds that can influence pro- and anti-inflammatory pathways. Interestingly, the effects of egg consumption on inflammation varies across different populations, including those that are classified as healthy, overweight, metabolic syndrome, and type 2 diabetic. The following review will discuss the pro- and anti-inflammatory properties of egg components, with a focus on egg phospholipids, cholesterol, the carotenoids lutein and zeaxanthin, and bioactive proteins. The effects of egg consumption of inflammation across human populations will additionally be presented. Together, these findings have implications for population-specific dietary recommendations and chronic disease risk.

The growing presence of products on the market with added value in terms of health makes essential their regulation and harmonization in critical aspects such as safety. The toxicology applied to the bioactive compounds should demonstrate the absence of toxic effects at doses advised for consumption, as well as evaluate the potential toxic effects in the assumption that the products are used in quantities superior to those recommended. The specific strategy should be defined case by case; therefore, prior to any toxicological development, it is essential to study all the information regarding the bioactive compounds (BACs) characterization, nutridynamics and nutrikinetics, that is available. In this guideline, a general strategy to be applied in the development of BACs is proposed. It includes a first in vitro phase to discard genotoxicity and endocrine effects and a second in vivo phase with different possibilities regarding the duration and the extension of the studies.

Objective: We aimed to use the meta-analysis method to assess the relationship between coffee drinking and all-cause mortality., Design: Categorical and dose-response meta-analyses were conducted using random-effects models., Setting: We systematically searched and identified eligible literature in the PubMed and Scopus databases., Subjects: Seventeen studies including 1 054 571 participants and 131 212 death events from all causes were included in the present study., Results: Seventeen studies were included and evaluated in the meta-analysis. A U-shaped dose-response relationship was found between coffee consumption and all-cause mortality (P for non-linearity <0.001). Compared with non/occasional coffee drinkers, the relative risks for all-cause mortality were 0.89 (95 % CI 0.85, 0.93) for 1-<3 cups/d, 0.87 (95 % CI 0.83, 0.91) for 3-<5 cups/d and 0.90 (95 % CI 0.87, 0.94) for ≥5 cups/d, and the relationship was more marked in females than in males., Conclusions: The present meta-analysis of prospective cohort studies indicated that light to moderate coffee intake is associated with a reduced risk of death from all causes, particularly in women.

Developments in food science and technology have accelerated the production and availability of health foods. Although consumers may acquire health benefits from some products, they may also suffer adverse health effects and economic losses. Unlike medicine, which is administered by health professionals, foods are chosen directly by the consumer and can be used at their own discretion. Food labeling plays a major role in providing consumers with proper information when choosing the desired products; however, the food labeling system is complex and inadequately understood by consumers. Moreover, there are some products that do not follow food labeling laws and contain ingredients that have not undergone proper effectiveness and safety evaluations. With the increasing popularity of health foods, it is becoming more important to ensure that they are effective and safely used. The biggest concern is that some consumers may mistake health foods for medicines that can cure or prevent diseases. The main reason that consumers are confused and misled is due to the vast amount of information that is available. This paper provides an overview of the following four approaches that we have taken in order to develop countermeasures against health foods being used improperly by consumers: (1) conducting a survey of actual health food use; (2) collecting data on adverse events suspected to be caused by health foods, and evaluating the causal relationship with methods suited to investigating health foods; (3) examining the safety of natural ingredients used in health foods; and (4) constructing an online database that compiles information on the safety and effectiveness of health foods and/or ingredients, and sharing such information with consumers and health professionals.

In the recent years, a growing interest for nutraceutical algae (tablets, capsules, drops) has been developed, due to their effective health benefits, as a potential alternative to the classic drugs. This review explores the use of cyanobacterium Spirulina, the microalgae Chlorella, Dunaliella, Haematococcus, and the macroalgae Klamath, Ascophyllum, Lithothamnion, Chondrus, Hundaria, Glacilaria, Laminaria, Asparagopsis, Eisenia, Sargassum as nutraceuticals and dietary supplements, in terms of production, nutritional components and evidence-based health benefits. Thus, our specific goals are: 1) Overview of the algae species currently used in nutraceuticals; 2) Description of their characteristics, action mechanisms, and possible side effects; 3) Perspective of specific algae clinical investigations development.

Purpose: Consumption of pulses is recommended to improve diet quality and decrease the risk of chronic disease. However, their constituent α-galactosides, including raffinose, are commonly thought to contribute to unpleasant gastrointestinal symptoms., Methods: Using a random crossover design, healthy adults (n = 12) received control foods, control foods with 5 g raffinose, and foods with 200 g of canned chickpea (11 g fibre per day), each for three weeks following a 3-day diet rotation. Gastrointestinal symptoms (rating 0 = none to 3 = severe), compliance, and stool frequency were recorded daily., Results: No change in daily stool frequency (mean ± SD) was found with chickpea (1.7 ± 0.3) or raffinose (1.7 ± 0.4) compared with control (1.5 ± 0.3). Reported flatulence (mean ± SD) was rated higher with chickpea (1.0 ± 0.2, P < 0.001) and raffinose (0.7 ± 0.2, P < 0.001) compared with control (0.4 ± 0.1). Although bloating was infrequent, ratings were higher with chickpea (0.2 ± 0.1, P < 0.001) and raffinose (0.3 ± 0.1, P < 0.001) compared with control (0.0). No differences were found for diarrhea or abdominal pain., Conclusions: As gastrointestinal symptoms were mild for most participants, canned chickpea may be a feasible way of increasing pulse intake and improving overall diet quality.
