The purpose of this study was to examine the effects of plant- versus animal-based food intake before exercise on arterial function and subsequent aerobic exercise capacity. Eleven healthy adult males (mean age, 22.6 ± 1.8 years) participated in this study. A plant- or animal-based randomized meal type crossover comparison was conducted on separate days with a uniform protein, fat, and carbohydrate balance. Both carotid–femoral pulse wave velocity (cfPWV), femoral–ankle pulse wave velocity (faPWV), and brachial artery flow-mediated dilatation (FMD) were measured as indexes of aortic and peripheral arterial stiffness and vascular endothelial function, respectively, before and at 120 min after the meal. After these measurements, maximal oxygen uptake was assessed using a graded power test on an electronically braked cycle ergometer. The results revealed that cfPWV was significantly lower, whereas FMD was significantly higher, at 120 min after compared with before the plant-based meal (p = 0.01 and 0.02, respectively). By contrast, cfPWV and FMD did not change at 120 min after compared with before the animal-based meal. In addition, faPWV did not change at 120 min after compared with before the meal for either meal type. Maximal oxygen uptake was higher in the plant- than in the animal-based meal type (p = 0.02). These results suggest that pre-exercise plant-based food intake may improve central arterial stiffness and vascular endothelial function, which may have favorable implications for aerobic exercise capacity.

Simple Summary: Optimal human health requires the adequate provision of all nutrients in the correct proportions, ensuring the provision of energy and essential small molecules. All primates, including humans, are omnivorous but the most striking difference from other primates is the remarkable diversity of the diets we consume. Animal-sourced foods are important for human nutrition and health, but they can have a negative impact on the environment. The aim here is to examine these impacts that can result in land use tensions associated with population growth and the loss of native forests and wetlands during agricultural expansion, increased greenhouse gas emissions, and high water use with poor water quality outcomes. However, several technologies and practices can be used to mitigate against these impacts. These include grazing when feed quality is high, the use of dietary additives, breeding of animals with higher growth rates and increased fecundity, rumen microbial manipulations using vaccines and other additives, soil management to reduce nitrous oxide emission, management systems to improve carbon sequestration, improved nutrient use efficacy, use of cover crops, low-emission composting barns, covered manure storages, and direct injection of animal slurry into soil. Other technologies and systems to provide further solutions continue to be researched. Animal-sourced foods are important for human nutrition and health, but they can have a negative impact on the environment. These impacts can result in land use tensions associated with population growth and the loss of native forests and wetlands during agricultural expansion. Increased greenhouse gas emissions, and high water use but poor water quality outcomes can also be associated. Life cycle analysis from cradle-to-distribution has shown that novel plant-based meat alternatives can have an environmental footprint lower than that of beef finished in feedlots, but higher than for beef raised on well-managed grazed pastures. However, several technologies and practices can be used to mitigate impacts. These include ensuring that grazing occurs when feed quality is high, the use of dietary additives, breeding of animals with higher growth rates and increased fecundity, rumen microbial manipulations through the use of vaccines, soil management to reduce nitrous oxide emission, management systems to improve carbon sequestration, improved nutrient use efficacy throughout the food chain, incorporating maize silage along with grasslands, use of cover crops, low-emission composting barns, covered manure storages, and direct injection of animal slurry into soil. The technologies and systems that help mitigate or actually provide solutions to the environmental impact are under constant refinement to enable ever-more efficient production systems to allow for the provision of animal-sourced foods to an ever-increasing population.

Simple Summary: Optimal human health requires the adequate provision of all nutrients in the correct proportions, ensuring the provision of energy and essential small molecules. All primates, including humans, are omnivorous, but our most striking difference from other primates is the remarkable diversity of diet we consume. The aim here is to examine the benefits and possible unintended consequences of using herbivore-based foods on human and animal health and welfare. The advantages of using grazed pasture for ruminant meat and milk production include (1) animal-sourced foods contain essential amino acids and micronutrients, and almost always have a higher digestibility than plant proteins, (2) greater use of pasture to feed animals could result in less use of food that could be used for human consumption, e.g., maize, soybean, and cereal crops, (3) ruminants can provide food from land otherwise unable to be used for cropping, consume feed that cannot be eaten directly by humans, and provide more than just food—they also provide leather and fibre. Animal-sourced foods are an important part of the human diet, and while some unintended consequences associated with animal health and herd management have occurred, technologies and systems to provide solutions to these are available and under refinement. Human health and diet are closely linked. The diversity of diets consumed by humans is remarkable, and most often incorporates both animal and plant-based foods. However, there has been a recent call for a reduced intake of animal-based foods due to concerns associated with human health in developed countries and perceived impacts on the environment. Yet, evidence for the superior nutritional quality of animal-sourced food such as meat, milk, and eggs, compared with plant-based foods, indicates that consumption of animal-sourced food should and will continue. This being the case, the aim here is to examine issues associated with animal-sourced foods in terms of both the quantification and mitigation of unintended consequences associated with environment, animal health, and herd management. Therefore, we examined the role of animal proteins in human societies with reference to the UN-FAO issues associated with animal-sourced foods. The emphasis is on dominant grazed pastoral-based systems, as used in New Zealand and Ireland, both with temperate moist climates and a similar reliance on global markets for generating net wealth from pastoral agricultural products. In conclusion, animal-sourced foods are shown to be an important part of the human diet. Production systems can result in unintended consequences associated with environment, animal health, and herd management, and there are technologies and systems to provide solutions to these that are available or under refinement.

Abstract Background It remains unclear whether plant-based or animal-based dietary patterns are more beneficial for older adults more in maintaining muscle mass. Using a prospective cohort with nationwide sample of China older adults in this study, we aimed to examine the relationship between adhering to plant-based diet patterns or animal-based diet patterns and muscle loss. Methods We included 2771 older adults (≥ 65 years) from the Chinese Longitudinal Health Longevity Survey (CLHLS) with normal muscle mass at baseline (2011 and 2014 waves), which followed up into 2018. Plant-based dietary pattern scores and preference subgroups were constructed using 16 common animal-based and plant-based food frequencies. We used the corrected appendicular skeletal muscle mass (ASM) prediction formula to assess muscle mass. We applied the Cox proportional hazard risk regression to explore associations between dietary patterns and low muscle mass (LMM). Results During a mean of 4.1 years follow-up, 234 (8.4%) participants with normal muscle mass at baseline showed LMM. The plant-based dietary pattern reduced the risk of LMM by 5% (Hazard Ratios [HR]: 0.95, 95% confidence intervals [95%CI]: 0.92–0.97). In addition, a high plant-based food company with a high animal-based food intake pattern reduced the risk of LMM by 60% (HR: 0.40, 95% CI: 0.240–0.661) and 73% (HR: 0.27, 95% CI: 0.11–0.61) in the BADL disability and IADL disability population compared with a low plant-based food and high animal-based food intake, whereas a high plant-based food and low animal-based food intake was more beneficial in reducing the risk of LMM in the normal BADL functioning (HR: 0.57, 95% CI: 0.35–0.90) and IADL functioning (HR: 0.51, 95% CI: 0.28–0.91) population. Conclusions When it comes to maintaining muscle mass in older Chinese people with functional independence, a plant-based diet pattern is more beneficial and effective than the animal-based one. People with functional dependence may profit from a combination of plant-based and animal-based diets to minimize muscle loss.

Background: There is growing evidence that substituting animal-based with plant-based foods is associated with a lower risk of cardiovascular diseases (CVD), type 2 diabetes (T2D), and all-cause mortality. Our aim was to summarize and evaluate the evidence for the substitution of any animal-based foods with plant-based foods on cardiometabolic health and all-cause mortality in a systematic review and meta-analysis. Methods: We systematically searched MEDLINE, Embase, and Web of Science to March 2023 for prospective studies investigating the substitution of animal-based with plant-based foods on CVD, T2D, and all-cause mortality. We calculated summary hazard ratios (SHRs) and 95% confidence intervals (95% CI) using random-effects meta-analyses. We assessed the certainty of evidence (CoE) using the GRADE approach. Results: In total, 37 publications based on 24 cohorts were included. There was moderate CoE for a lower risk of CVD when substituting processed meat with nuts [SHR (95% CI): 0.73 (0.59, 0.91), n = 8 cohorts], legumes [0.77 (0.68, 0.87), n = 8], and whole grains [0.64 (0.54, 0.75), n = 7], as well as eggs with nuts [0.83 (0.78, 0.89), n = 8] and butter with olive oil [0.96 (0.95, 0.98), n = 3]. Furthermore, we found moderate CoE for an inverse association with T2D incidence when substituting red meat with whole grains/cereals [0.90 (0.84, 0.96), n = 6] and red meat or processed meat with nuts [0.92 (0.90, 0.94), n = 6 or 0.78 (0.69, 0.88), n = 6], as well as for replacing poultry with whole grains [0.87 (0.83, 0.90), n = 2] and eggs with nuts or whole grains [0.82 (0.79, 0.86), n = 2 or 0.79 (0.76, 0.83), n = 2]. Moreover, replacing red meat for nuts [0.93 (0.91, 0.95), n = 9] and whole grains [0.96 (0.95, 0.98), n = 3], processed meat with nuts [0.79 (0.71, 0.88), n = 9] and legumes [0.91 (0.85, 0.98), n = 9], dairy with nuts [0.94 (0.91, 0.97), n = 3], and eggs with nuts [0.85 (0.82, 0.89), n = 8] and legumes [0.90 (0.89, 0.91), n = 7] was associated with a reduced risk of all-cause mortality. Conclusions: Our findings indicate that a shift from animal-based (e.g., red and processed meat, eggs, dairy, poultry, butter) to plant-based (e.g., nuts, legumes, whole grains, olive oil) foods is beneficially associated with cardiometabolic health and all-cause mortality.

Animal based-food products represent an essential source of protein supply in overall diets, and livestock provide 25% of the total protein content consumed by humans as food. Concurrently, livestock significantly impacts the environment, being responsible for 10–12% of total anthropogenic CO2 emissions. Among livestock, pork is considered one that accounts for the greatest impact in terms of emissions, about 4.62 kg CO2 eq/kg. Furthermore, the growing global demand for protein sources has led to a widespread need to find agri-food solutions that meet the demand for food through sustainable production systems. The high nutritional quality of edible insects, in terms of amino acids, fats, minerals, and vitamins, is comparable with meat products. This study aims to compare protein production from pork and mealworm, assessing the degree of substitution and environmental impacts of the two production systems. To assess the impacts of protein production from mealworms and pork on the ecosystem, resources, and human health, an LCA was conducted using the ReCiPe 2016 Endpoint method, with a 100-year hierarchical perspective (H) V1.05. It emerged that pork production is characterized by high impacts on the ecosystem, land use, climate-altering emissions, and fossil resources, in contrast with mealworm protein production. The low impact of insect protein production and the high nutritional values make edible insects a sustainable solution to growing food demand and economic benefits render edible insects globally a major potential future food.

Vegetarian foods are plant-based (PB) foods, often perceived as healthier foods than animal-based (AB) foods. The objective of this study was to analyze the nutritional quality of a set of PB foods (meat, milk and dairy products) marketed in Spain, and to compare their nutrient profiles with respect to some AB counterparts. Nutritional information per 100 g or mL, ingredients, and nutritional declarations, as well as the Nutri-Score, NOVA, and Eco-Score of each food were collected from Open Food Facts. Differences in the nutrient compositions between PB foods and their counterparts, and between the different groups of PB foods, were assessed at a 5% significance level. A total of 544 PB foods and 373 AB foods were identified. Overall, PB foods had a higher median content of fiber and carbohydrates, but a lower amount of proteins (except PB "meat" analogues: 14 g) and saturated fats (except PB "cheese alternatives": 12.5 g), than the AB counterparts (p < 0.05). PB "milk alternatives", particularly oat "milk", showed a higher median content of total carbohydrates (8 g) and sugars (5.5 g) compared to cow milks (4.7 g carbohydrates/sugars, on average; p < 0.001). PB "meat alternatives" also had a significantly higher value of carbohydrates (9 g) than AB meats (2 g, on average; p < 0.001). PB foods were mostly classified as Nutri-Score A and B (86%). However, more than half of them were of NOVA groups 3 and 4. Thus, there is a great diversity of PB meat and milk/dairy product alternatives on the Spanish market. Despite being products of good nutritional quality compared to AB foods, they also carry drawbacks that could have an impact on nutritional health. [ABSTRACT FROM AUTHOR]

This study reports a novel surface modification of polyurethane sponge (PUS) with acylated graphene oxide (AGO), yielding a versatile sorbent material (AGO@PUS) for the efficient extraction of sulfonamide residues from milk samples. The AGO@PUS combines the extractive properties of AGO with the advantages of PUS, enabling easy, fast, cost-effective, and efficient sample preparation. The material was characterized using FTIR, SEM, XRD and the extraction protocol was optimized for the determination of three sulfonamides (SGD, SDS, and SDZ) by HPLC-UV. The proposed method exhibited excellent linearity (0.01–1000 µg mL−1), low limits of detection (0.04–0.06 µg mL−1) and quantification (0.13–0.21 µg mL−1), and high coefficients of determination (R2 = 0.993–0.997). The maximum recovery rate reached 99.63 %, demonstrating the exceptional sorption capacity of AGO@PUS. Notably, the clear extracts obtained with this material highlight its potential for efficient sample preparation and analysis. • Functionalization of polyurethane sponges with acylated graphene oxide • A superhydrophobic sorbent for the extraction of sulfonamides • Development of SPE method • Determination and quantification of sulfonamides using HPLC [ABSTRACT FROM AUTHOR]

Based on the provincial panel data from 2008 to 2019, this paper constructs a mediating effect model to analyze the impact of China's agricultural insurance development on the nutritional status of rural residents theoretically and empirically. This study found that agricultural insurance significantly affects the nutritional status of rural residents through two mediators: increased income level and the regional crop diversity. Meanwhile, regional heterogeneity exists in the impact of agricultural insurance on the nutritional status of rural residents. Overall, this paper argues that agricultural insurance should be one of the tools to improve the nutritional status of rural residents in China. Specifically, the design and implementation process of policy-based agricultural insurance should put the nutritional health of rural residents and their complex impact into consideration. Therefore, this paper suggests that even though agricultural insurance can facilitate rural residents' income stability and generation, relevant stakeholders also need to draw awareness, popularize the importance of nutrition and health, and optimize the supply structure of agricultural products.

Purpose: While intensive modern food systems have significant unfavourable impacts on health and the environment, new sustainable food consumption trends have been emerging in recent years. This study identified recent dietary trends over a 4-year period in terms of overall dietary patterns and organic foods consumption and associated socio-demographic determinants. Methods: Food intakes were assessed among 18,108 participants of the NutriNet-Santé cohort in 2014 and 2018. A food frequency questionnaire was used to estimate organic and conventional food consumption. Change in food consumption, quality of the diet (assessed by the adherence to the French national guidelines), plant-based diet using published scores, organic food intake were evaluated in regard with various socio-demographic factors. The paired student t test to compare dietary intake and the Kruskal–Walllis test to consider socio-demographic characteristics were used. Results: Consumption of meat and processed meat decreased respectively by 5.09 g/day (SD 51.15) and 1.12 g/day (SD 26.05). The average total consumption of organic products increased by 12% (+ 93 g/day) while consumption of organic fish and seafood (− 1.4 g/day), poultry (− 1 g/day), processed meat (− 0.3 g/day) and meat (− 3.3 g/day) decreased. The dietary towards healthier diets was more pronounced in certain population subgroups. For example, females, young individuals and postgraduate participants were more likely to increase their consumption of healthful plant and animal-based foods, organic foods and to improve the overall nutritional quality of their diets during the follow-up period than their counterparts. Conclusion: Our results indicate a slight inflexion towards healthier and plant-based diets over a 4-year period at least in some segments of the population. A decrease in the consumption of animal products and an increase in the consumption of healthful plant-based foods and organic foods suggests a potential trend towards more sustainable diets among certain subgroups. The environmental impacts of these changes need to be assessed in further works as well as the way to sustain and improve them, in particular those who do not initiate sustainable transition.

Herein, we developed a novel integrated apparatus to perform phase separation based on magnetic-stirring, salt-induced, liquid-liquid microextraction for determination of five fluoroquinolones in animal-based foods by HPLC analysis. The novel integrated apparatus consisted of three simple HDPE (high density polyethylene) parts that were used to separate the solvent from the aqueous solution prior to retrieving the extractant. The extraction parameters were optimized using the response surface method based on central composite design: 791 μL of acetone solvent, 2.5 g of Na2SO4, pH 1.7, 3.0 min of stir time, and 5.5 min centrifugation. The limits of detection were 0.07-0.53 μg kg(-1) and recoveries were 91.6-105.0% for the five fluoroquinolones from milk, eggs and honey. This method is easily constructed from inexpensive materials, extraction efficiency is high, and the approach is compatible with HPLC analysis. Thus, it has excellent prospects for sample pre-treatment and analysis of fluoroquinolones in animal-based foods.

Objective: This study examines secular changes in diet-related greenhouse gas emissions (GHGE) in younger and older Swedish adults, since the turn of this century.Design: Two cross-sectional health examination surveys were conducted in 2001-2004 (T1) and 2014-2018 (T2). At both times, an eighty-six-item FFQ was embedded in the survey. From the food frequencies and age-standardised portion sizes, GHGE estimates (kg CO2e/year) were calculated. GHGE was modelled as a function of time period and covariates, for five distinct age groups.Setting: The municipality of Gothenburg, in western Sweden.Participants: Women and men aged 25-34, 35-44, 45-54, 55-64 and 65-75 years were randomly selected from the population registry and recruited for examinations. After exclusion of participants with incomplete dietary data, the analytic sample consisted of 2569 individuals at T1 and 2119 at T2.Results: Lower dietary GHGE scores were observed at T2 compared with T1, in each age group, adjusting for sex, BMI and education. The largest differences in GHGE were observed in the youngest age group (approximately 30 % reduction). Decreasing trends in GHGE from animal-based foods were observed at all ages and were accompanied by smaller increases from plant-based sources in younger groups only. At all ages, GHGE from discretionary foods decreased, and prevalence of overweight remained stable.Conclusions: Optimal dietary trends should support both human health and planetary health. Our results suggest that Swedish adults have moved in this direction, e.g. through less intake of red meat products and stable weight status. [ABSTRACT FROM AUTHOR]

Substitution models in epidemiologic studies specifying both substitute and substituted food in relation to disease risk may be useful to inform dietary guidelines. A systematic review of prospective observational studies was performed to quantify the risks of all-cause mortality, cardiovascular disease, and type 2 diabetes (T2D) associated with the substitution of dairy products with other foods and between different dairy products. We systematically searched MEDLINE, Embase, and Web of Science until 28th June, 2023. We calculated summary relative risks (SRRs) and 95% confidence intervals (95% CI) in random-effects meta-analyses. We assessed the risk of bias with the Risk Of Bias In Non-randomized Studies - of Exposure (ROBINS-E) tool and certainty of evidence (CoE) using the Grading of Recommendations Assessment, Development, and Evaluations (GRADE) approach. Fifteen studies (with 34 publications) were included. There was moderate CoE that the substitution of low-fat dairy with red meat was associated with a higher risk of mortality, coronary artery disease, and T2D [SRR (95% CI): 1.11 (1.06, 1.16), 1.13 (1.08, 1.18), and 1.20 (1.16, 1.25)]. A higher risk of mortality and T2D was also observed when substituting low-fat dairy with processed meat [SRR (95% CI): 1.19 (1.11, 1.28) and 1.41 (1.33, 1.49); moderate CoE]. A lower mortality risk was associated with the substitution of dairy and yogurt with whole grains [SRR (95% CI): 0.89 (0.84, 0.93) and 0.91 (0.85, 0.97)], and butter with olive oil [SRR (95% CI): 0.94 (0.92, 0.97); all moderate CoE]. Mainly no associations were observed when substituting dairy products against each other on disease and mortality risk. Our findings indicate associations between substituting dairy with red or processed meat and higher disease risk, whereas its substitution with whole grains was associated with a lower risk. However, there is little robust evidence that substituting whole-fat with low-fat dairy is associated with disease risk. (CRD42022303198)., (© 2024 The Author(s).)

• We collect a sample of more than 50,000 food demand elasticities from 444 studies. • The data covers 87 countries and 14 food groups, with 10 animal food products. • We estimate meta-regressions for expenditure, own-, and cross-price elasticities. • Predicted animal food elasticities reflect socio-economic and cultural variations. • Our estimates can help formulate food policy promoting sustainable food systems. Animal food products are featured prominently in current debates on dietary transitions. Food demand projections and policy evaluations often draw on expenditure and price elasticity estimates; thus, it is crucial that these elasticities are robust at an adequate product disaggregation, well-founded, and comparable both across products and countries. To the extent of our knowledge, there is no analysis providing meta-elasticities for all world regions, all food groups, and disaggregated animal foods. In this study, we cover this gap and collect a database with more than 50,000 demand elasticities from 444 studies and 87 countries. As 50% of our sample involves animal food products, we are able to provide food demand meta-elasticities for 14 food groups, of which ten are animal food. We present a set of estimated expenditure, own-price, and cross-price; unconditional and conditional; and uncompensated and compensated elasticities; and discuss their policy implications.

The modern-day Western consumers will need to accept purchasing their foodstuffs from the typically chain organised supermarkets relying on the main supply chains of food, which are produced within the mass production paradigm of contemporary agriculture. There will be some exceptions from this main rule, but for the contemporary Western citizen, these exceptions will not suffice to secure subsistence on a standalone basis. To an increasing number of Western consumers, animal welfare aspects connected to modern farming practices are concerning, and increasingly being viewed as systematic mistreatment of animals. For those adhering to a Christian morality, the question arises as to whether consuming animal-based food produced under the modern agricultural paradigm may be in violation of their scripturally based stewardship obligations under the covenant with God in creation. Further, if in violation of their moral obligations, the question becomes whether the acceptance of modern animal husbandry practices as in reality, the sole source of animal-based foodstuffs for physical subsistence will also be a violation of the consumers’ right to religious expression and observance as guaranteed under United Nations (UN)’s Universal Declaration of Human Rights. These questions are elaborated on in this article, and briefly contrasted against the observance of religiously oriented rules connected to foodstuffs under the Islamic and Judaic paradigms. A system for marking animal-based foodstuffs according to Christian-ethical norm alignment is suggested.

Agriculture supplies human with foods, and were considered as a crucial source of artificial greenhouse gas (GHG) emissions. Life-cycle carbon footprint (CF) could represent the comprehensive GHG emissions from foods, and attracted attentions from researchers. Previous studies had evaluated the CFs of quite a few foods including both plant- and animal-based products. However, the huge differences from system boundary definition, emission factors limited the comparability of the reported CF results. A few studies had tried to evaluate and compare the CFs of some plant products or animal products. However, the CF comparisons between plant- and animal-based foods were rarely reported. Here we used a consistent methodology, including unique life cycle definitions, identical data sources, and same byproducts allocation method to calculate CFs of 22 plant-based foods and 6 animal-based foods, as well as some processed foods. The results showed that the animal-based foods had greater CFs than the plant-based foods in general. Beef and mutton emitted more GHGs than the other foods, and the lowest CF was observed in the radish production. Manufacturing and field emissions were major parts of the CFs for the plant-based foods. The CF compositions varied in different animal-based foods. Daily dietary GHG emission of Chinese was 0.84 kg CO 2 /capita. China had emitted more than 427.64 Tg CO 2 from dietary in 2013. Through measuring the impact of different foods on global warming, and quantifying the CF differences of various foods, this study can help to improve the comparability of the CF between plant- and animal-based foods. The results offered an instruction for GHG mitigation through choosing foods with lower CFs. The methodology developed in this study can also be used as a reference for the CF comparisons among different products. [ABSTRACT FROM AUTHOR]

To assess the health risks due to food consumption, the human daily intake and uptake of organochlorine pesticides, polychlorinated biphenyls, polybrominated diphenyl ethers, polycyclic aromatic hydrocarbons, and toxic trace elements (mercury, chromium, cadmium, lead, and arsenic) were estimated based on the animal-based foods collected from markets in Shanghai, China. The estimated daily intake and uptake considering the contaminant bioaccessibility via single food consumption were 9.4-399 and 4.2-282 ng/kg body weight/day for adults, and 10.8-458 and 4.8-323 ng/kg body weight/day for children, respectively. These values were 0.2-104 and 0.05-58.1, and 0.2-119 and 0.06-66.6 ng/kg body weight/day via multiple food consumption for adults and children, respectively. According to the United States Environmental Protection Agency risk assessment method, the non-cancer and cancer health risks posed by the contaminants were estimated using the hazard quotient and the lifetime cancer risk method, respectively. The results showed that the combined hazard quotient values for multiple contaminants via single or multiple food consumption were below 1, suggesting that the residents in Shanghai would not experience a significant non-cancer health risk. Among the contaminants investigated, the potential non-cancer risk of methylmercury was highest. However, the combined cancer risk posed by multiple contaminants in most foods exceeded the accepted risk level of 10, and inorganic arsenic was the main contributor. The risks caused by polybrominated diphenyl ethers for cancer and non-cancer effects were negligible. The cancer risk of inorganic arsenic is a matter of concern in animal-based foods from Shanghai markets. [ABSTRACT FROM AUTHOR]

We performed an umbrella review of dose-response meta-analyses of prospective studies reporting the incidence of type 2 diabetes associated with the consumption of animal-based foods. A systematic search was conducted in PubMed, Web of Science, Scopus, and Embase according to PRISMA. Thirteen meta-analyses are included in the study providing 175 summary risk ratio estimates. The consumption of 100 g/day of total or red meat, or 50 g/day of processed meat, were associated with an increased risk; RR and 95 % CI were respectively 1.20, 1.13-1.27; 1.22, 1.14-1.30 and 1.30, 1.22-1.39. White meat (50 g/day) was associated with an increased risk, but of lesser magnitude (RR 1.04, 95 % CI 1.00-1.08). A risk reduction was reported for 200 g/day of total dairy (RR 0.95, 95 % CI 0.92-0.98) or low-fat dairy (RR 0.96, 95 % CI 0.92-1.00) or milk (RR 0.90, 95 % CI 0.83-0.98), or 100 g/day of yogurt (RR 0.94, 95 % CI 0.90-0.98). No association with diabetes risk was reported for fish or eggs. In conclusions animal-based foods have a different association with diabetes risk. To reduce diabetes risk the consumption of red and processed meat should be restricted; a moderate consumption of dairy foods, milk and yogurt, can be encouraged; moderate amounts of fish and eggs are allowed.

Abstract: The concentrations of four human essential trace elements [iron (Fe), manganese (Mn), zinc (Zn), chromium (Cr)] and non-essential elements [cadmium (Cd), lead (Pb), arsenic (As), and mercury (Hg)] in eighteen animal-based foods including meat, fish, and shellfish collected from markets in Shanghai, China, were analyzed, and the associated human daily intake and uptake considering bioaccessibility were estimated. The mean concentration ranges for eight trace elements measured in the foods were 3.98–131µgg−1 for Fe, 0.437–18.5µgg−1 for Mn, 5.47–53.8µgg−1 for Zn, none detected–0.101µgg−1 for Cr, 2.88×10−4–2.48×10−2 µgg−1 for Cd, 1.18×10−3–0.747µgg−1 for Pb, none detected–0.498µgg−1 for As, and 8.98×10−4–6.52×10−2 µgg−1 for Hg. The highest mean concentrations of four human essential elements were all found in shellfish. For all the trace elements, the observed mean concentrations are mostly in agreement with the reported values around the world. The total daily intake of trace elements via ingestion of animal-based food via an average Shanghai resident was estimated as 7371µgd−1 for the human essential elements and 13.0µgd−1 for the human non-essential elements, but the uptake decreased to 4826µgd−1 and 6.90µgd−1, respectively, after trace element bioaccessibility was considered. Livestock and fish for human essential and non-essential elements, respectively, were the main contributor, no matter whether the bioaccessibility was considered or not. Risk estimations showed that the intake and uptake of a signal trace element for an average Shanghai resident via ingestion animal-based foods from Shanghai markets do not exceed the recommended dietary allowance values; consequently, a health risk situation is not indicated.

Consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. Concurrently, older adults are recommended to consume an adequate amount of high-quality dietary protein for the prevention of age-related muscle loss. In the current Perspective article, we discuss why it may not be preferred to consume a vegan diet at an older age. Our perspective is based on the proposed lower bioavailability and functionality of proteins in a vegan diet due to the matrix of the whole-food protein sources, the lower essential amino acid (EAA) content, and specific EAA deficiencies in proteins derived from plant-based foods. We propose that a vegan diet increases the risk of an inadequate protein intake at an older age and that current strategies to improve the anabolic properties of plant-based foods are not feasible for many older adults. We provide recommendations for further research to substantiate the remaining knowledge gaps regarding the consequences of a vegan diet on skeletal muscle mass and strength at an older age., (© The Author(s) 2022.

Antimicrobial resistance has gradually become a serious problem threatening public health and food safety throughout the world. Biofilm is one of the important factors affecting the antimicrobial resistance of bacteria. Staphylococcus aureus usually has strong biofilm formation ability, and it is widely found in animal-based food. The purpose of this study is to determine the prevalence, antimicrobial resistance and biofilm formation of S. aureus in animal-based food. Total 959 samples representing eight types of animal-based foods were collected from randomly selected locations (21 supermarkets and 18 wet markets) throughout the Shanghai city. The overall isolation rate of S. aureus was 17.2% (165/959). For each food category, the isolation rate was 21.8% for chicken (45/206), 21.5% for pork (71/331), 15.2% for beef (16/105), 13.8% for duck (9/65), 12.1% for aquatic products (17/141), 8.6% for egg (5/58), and 7.1% for lamb (2/28), respectively. No isolate was found from pasteurized milk (n = 25). Antimicrobial susceptibility test showed that among all the S. aureus isolates, 90.3% were resistant to at least one antimicrobial, 39.4% were multi-drug resistant, and 23 isolates were methicillin-resistant S. aureus (MRSA). Comparing the resistance rates to different antimicrobials, S. aureus had the highest resistance rate to penicillin, up to 82.4% (136/165); followed by erythromycin (57.6%, 95/165) and tetracycline (27.9%, 46/165). All isolates were sensitive to vancomycin. With the microtiter plate and crystal violet staining assay, 64.8% of all the 165 isolates had strong biofilm formation ability and 20.0% were moderate producers. Remarkably, significant difference was found in biofilm formation ability between those isolates from supermarkets and wet markets (p < 0.01). According to WGS analysis of 19 multi-drug resistant isolates with strong biofilm formation ability, ST7 was the dominant sequence type. Combined analysis showed that S. aureus isolates with drug resistance phenotypes usually had stronger ability to form biofilm. • Contamination rate of Staphylococcus aureus in animal-based food was 17.2%. • Among the 165 isolates, 90.3% were resistant to at least one antimicrobial. • Among the 165 isolates, 64.8% had strong biofilm formation ability (BFA). • Among the 18 isolates with extremely strong BFA, 13 were from wet markets. • S. aureus isolates with drug resistance tend to be stronger biofilm producers.

Herein, we developed a novel integrated apparatus to perform phase separation based on magnetic-stirring, salt-induced, liquid-liquid microextraction for determination of five fluoroquinolones in animal-based foods by HPLC analysis. The novel integrated apparatus consisted of three simple HDPE (high density polyethylene) parts that were used to separate the solvent from the aqueous solution prior to retrieving the extractant. The extraction parameters were optimized using the response surface method based on central composite design: 791 μL of acetone solvent, 2.5 g of Na2SO4, pH 1.7, 3.0 min of stir time, and 5.5 min centrifugation. The limits of detection were 0.07-0.53 μg kg(-1) and recoveries were 91.6-105.0% for the five fluoroquinolones from milk, eggs and honey. This method is easily constructed from inexpensive materials, extraction efficiency is high, and the approach is compatible with HPLC analysis. Thus, it has excellent prospects for sample pre-treatment and analysis of fluoroquinolones in animal-based foods., (Copyright © 2014 Elsevier Ltd. All rights reserved.)
