Objectives: The objective of this study was to assess the influence of the European Youth Tackling Obesity-Kids (EYTO-Kids) 10-month intervention, based on social marketing and peer-led methodologies, at 16 month of its ending., Study Design: Children (aged 9 at baseline and 11 at the follow-up) from disadvantaged neighbourhoods who participated in the 10-month EYTO-Kids parallel-cluster randomised controlled intervention study in Reus (Spain) were included. The number of participants was 252 (retention rate: 67.2%) in the intervention group (7 schools) and 226 (retention rate: 69.1%) in the control one (8 schools). Primary (physical activity and fruit consumption) and secondary (screen time; and vegetables, fast food, and sugary drink consumption) outcomes were assessed., Results: At follow-up, consumption of ≥1 fruit per day increased in girls (odds ratio [OR] (95% confidence interval [CI]) = 2.28 (1.2; 4.2), P = 0.012) and all children (OR (95%CI) = 2.28 (1.0; 2.6), P = 0.044) in the intervention group vs. the control one. Physical activity ≥6 h/week similarly increased in both groups., Conclusion: At long-term effectiveness of a 10-month intervention on improving fruit consumption in children was observed. Therefore, peer-led and social marketing methodologies enhance healthy lifestyles by conveying children towards healthy choices., (Copyright © 2024 The Author(s). Published by Elsevier Ltd..

Background: Personalized nutrition (PN) has been proposed as a strategy to increase the effectiveness of dietary recommendations and ultimately improve health status., Objectives: We aimed to assess whether including omics-based PN in an e-commerce tool improves dietary behavior and metabolic profile in general population., Methods: A 21-wk parallel, single-blinded, randomized intervention involved 193 adults assigned to a control group following Mediterranean diet recommendations (n = 57, completers = 36), PN (n = 70, completers = 45), or personalized plan (PP, n = 68, completers = 53) integrating a behavioral change program with PN recommendations. The intervention used metabolomics, proteomics, and genetic data to assist participants in creating personalized shopping lists in a simulated e-commerce retailer portal. The primary outcome was the Mediterranean diet adherence screener (MEDAS) score; secondary outcomes included biometric and metabolic markers and dietary habits., Results: Volunteers were categorized with a scoring system based on biomarkers of lipid, carbohydrate metabolism, inflammation, oxidative stress, and microbiota, and dietary recommendations delivered accordingly in the PN and PP groups. The intervention significantly increased MEDAS scores in all volunteers (control-3 points; 95% confidence interval [CI]: 2.2, 3.8; PN-2.7 points; 95% CI: 2.0, 3.3; and PP-2.8 points; 95% CI: 2.1, 3.4; q < 0.001). No significant differences were observed in dietary habits or health parameters between PN and control groups after adjustment for multiple comparisons. Nevertheless, personalized recommendations significantly (false discovery rate < 0.05) and selectively enhanced the scores calculated with biomarkers of carbohydrate metabolism (β: -0.37; 95% CI: -0.56, -0.18), oxidative stress (β: -0.37; 95% CI: -0.60, -0.15), microbiota (β: -0.38; 95% CI: -0.63, -0.15), and inflammation (β: -0.78; 95% CI: -1.24, -0.31) compared with control diet., Conclusions: Integration of personalized strategies within an e-commerce-like tool did not enhance adherence to Mediterranean diet or improved health markers compared with general recommendations. The metabotyping approach showed promising results and more research is guaranteed to further promote its application in PN.

Background & Aims: Sarcopenia is a disabling muscular multifactorial disease involving the oxidation process in old-young adults. We aimed to evaluate the relationship between antioxidant-rich foods (A-RF) and sarcopenia (muscle mass, strength, and function) based on observational studies (OS), and to assess the effectiveness of antioxidant interventions in ≥55-year-old adults via randomized controlled trials (RCTs). Moreover, to confirm if the OS results were in accordance with the RCTs results., Methods: We searched in the MEDLINE®/PubMed, Cochrane Library, and CINAHL databases from 2000 to 2020 about sarcopenia and specific nutrients/foods. The risk of bias was assessed and meta-analyses were performed using the Review Manager program., Results: The systematic review included 28 studies (19 OS, 9 RCTs), whereas the meta-analysis included 4 RCTs. Results of the systematic review of OS revealed that higher A-RF consumption was associated with better sarcopenia outcomes. Results of the RCTs meta-analysis indicated that higher fruit/vegetable consumption, supplementation with magnesium, and vitamin E plus vitamin D and protein significantly reduced the time to complete 5 stands (mean difference; 95% CI; -1.11 s; 1.70, -0.51; p < 0.01). Additionally, including tea catechin supplementation significantly increased handgrip strength (1.02 kg; 0.60, 1.44; p < 0.01)., Conclusions: In sum, A-RF or antioxidant supplementation could be effective tools for sarcopenia, especially improving muscle strength and function. The best interventions according to the meta-analysis of the RCTs were supplementation of vitamin E in combination with vitamin D and protein, magnesium, tea catechins, and increasing fruit and vegetable consumption., Registration Number: PROSPERO (CRD42020183045)., Competing Interests: Declaration of competing interest No potential conflict of interest is reported by the authors., (Copyright © 2022 The Author(s).

Background & Aims: Whether bioactive lysophospholipids (lyso-PLs) and trimethylamine-N-oxide (TMAO) serve as non-invasive biomarkers in early human hypercholesterolemia (HC) is unknown. This study aimed to assess whether serum lyso-PLs and plasma TMAO may be suitable susceptibility/risk biomarkers of HC in humans. Secondarily, we aimed to evaluate the relationships between targeted metabolites, diet composition and circulating liver transaminases, and verify these results in hamsters., Methods: A targeted metabolomics and lipidomics approach determined plasma TMAO and serum lysophosphatidylcholines (lyso-PCs) and lysophosphatidylethanolamines (lyso-PEs) in low (L-LDL-c) and moderate to high (MH-LDL-c) LDL-cholesterol subjects. Additionally, the relationships between targeted metabolites, liver transaminases and diet, particularly fatty acid intake, were tested. In parallel, plasma and liver lyso-PL profiles were studied in 16 hamsters fed a moderate high-fat (HFD) or low-fat (LFD) diet for 30 days., Results: Predictive models identified lyso-PC15:0 and lyso-PE18:2 as the most discriminant lyso-PLs among groups. In MH-LDL-c (n = 48), LDL-cholesterol and saturated FAs were positively associated with lyso-PC15:0, whereas in L-LDL-c (n = 70), LDL-cholesterol and polyunsaturated fatty acids (PUFAs) were negatively and positively related to lyso-PE18:2, respectively. Interestingly, in MH-LDL-c, the lower lyso-PE 18:2 concentrations were indicative of higher LDL-cholesterol levels. Intrahepatic accumulation of lyso-PLs-containing essential n-6 PUFAs, including lyso-PE18:2, were higher in HFD-fed hamsters than LFD-fed hamsters., Conclusions: Overall, results revealed a possible hepatic adaptive mechanism to counteract diet-induced steatosis in animal and hypercholesterolemia progression in humans. In particular, low serum lyso-PE18:2 suggests a suitable susceptibility/risk biomarker of HC in humans., Competing Interests: Conflict of Interest The authors declare no conflicts of interest., (Copyright © 2021 The Authors.

Scope: Hesperidin exerts cardiovascular beneficial effects, but its mechanisms of action remain undefined. In a previous study we demonstrated that a single dose and a 12-week treatment of hesperidin decreased systolic blood pressure. The aim of this study was to ascertain the action mechanisms of hesperidin consumption in subjects with elevated blood pressure or with stage 1 hypertension, by determining their transcriptomic profile after a single dose or a 12-week treatment., Methods and Results: For transcriptomic analysis, peripheral blood mononuclear cells were obtained from 37 subjects with elevated blood pressure and stage 1 hypertension from CITRUS study who were randomized to receive for 12 weeks: control drink (CD; n = 11), OJ (containing 345 mg of hesperidin; n = 15) or EOJ (containing 600 mg of hesperidin; n = 11). Before starting the 12-weeks treatment, a single dose study with a 6 h of follow-up in each group was performed. After the single dose consumption, EOJ versus OJ, downregulated DHRS9 gene which is related with insulin resistance. Compared to CD, 12-week treatment of EOJ downregulated 6 proinflammatory genes while after OJ consumption only 1 proinflammatory gene was downregulated. Moreover, 12-week treatment of EOJ versus OJ, downregulated acute coronary syndrome gene related (SELENBP1)., Conclusion: A single dose consumption of EOJ could protect from insulin resistance. Moreover, EOJ decrease the expression of proinflammatory genes after 12-week treatment providing a possible mechanism of action on inflammation pathway., Competing Interests: Conflict of interest The authors declare that they have not conflicts of interest with the content of this article., (Copyright © 2021.

Background & Aims: The integrity of the intestinal barrier in the diseased is key to prevent further complications and disease such as sepsis and death, whereas, the role of food bioactive molecules (i. e. phenolic compounds (PCs) on the intestinal barrier, is still unknown. The current aim was to explore the benefits of the oral PC administration on the intestinal barrier integrity in animals., Methods: The effects of PCs on the intestinal barrier integrity in in vivo animal models of intestinal inflammation were assessed up-to August 2020 from the PubMed, SCOPUS, and Cochrane Library databases under the PRISMA methodology. The risk of bias was assessed from ARRAY and SCYRCLE tools., Results: From 1241 articles, 14 studies were included. In animals, oral resveratrol (n = 6) improves the intestinal barrier integrity and reduces intestinal damage. Additionally, grape seed extract (n = 2), curcumin (n = 1), genistein (n = 1), chlorogenic acid (n = 1), grape pomace (n = 1), olive leaf (n = 1) or cranberry extract (n = 1) improve the intestinal barrier integrity downregulating various inflammatory molecules (TNF-α, and other interleukins), and increasing the antioxidant enzymes in animals. Furthermore, resveratrol, quercetin, epigallocatechin, and other PCs improve the epithelial barrier integrity and pro-inflammatory molecule expression in the intestinal epithelia., Conclusions: The oral PC administration in animals improves the intestinal barrier integrity and function from three main mechanisms: 1) The reduction of pro-inflammatory molecules, 2) the improvement in tight-junction protein expression, and 3) the improvement of the antioxidant intracellular activity suggesting the potential use of PCs in the management of intestinal injury in humans, particularly for resveratrol, the most studied PC., Competing Interests: Conflict of interest The authors have declared no conflicts of interest.

Fermented dairy foods (FDFs) and probiotics are promising tools for the prevention and management of cardiometabolic diseases (CMDs), respectively. The relation between the regular consumption of FDFs and CMD risk factors was assessed by prospective cohort studies (PCSs), and the effect of probiotic supplementation added into a dairy matrix on CMD parameters was evaluated by randomized controlled trials (RCTs). Moreover, the effects of probiotic supplementation added into a dairy matrix were compared with those administered in capsule/powder form. Twenty PCSs and 52 RCTs met the inclusion criteria for the systematic review and meta-analysis. In PCSs, fermented milk was associated with a 4% reduction in risk of stroke, ischemic heart disease, and cardiovascular mortality [RR (95% CI); 0.96 (0.94, 0.98)]; yogurt intake was associated with a risk reduction of 27% [RR (95% CI); 0.73 (0.70, 0.76)] for type 2 diabetes (T2D) and 20% [RR (95% CI); 0.80 (0.74, 0.87)] for metabolic syndrome development. In RCTs, probiotic supplementation added into dairy matrices produced a greater reduction in lipid biomarkers than when added into capsules/powder in hypercholesterolemic subjects, and probiotic supplementation by capsules/powder produced a greater reduction in T2D biomarkers than when added into dairy matrices in diabetic subjects. Both treatments (dairy matrix and capsules/powder) resulted in a significant reduction in anthropometric parameters in obese subjects. In summary, fermented milk consumption is associated with reduced cardiovascular risk, while yogurt intake is associated with a reduced risk of T2D and metabolic syndrome development in the general population. Furthermore, probiotic supplementation added into dairy matrices could be considered beneficial for lowering lipid concentrations and reducing anthropometric parameters. Additionally, probiotic capsule/powder supplementation could contribute to T2D management and reduce anthropometric parameters. However, these results should be interpreted with caution due to the heterogeneity of the studies and the different probiotic strains used in the studies. This trial is registered with PROSPERO (CRD42018091791) and the protocol can be accessed at http://www.crd.york.ac.uk/PROSPERO/display&#95;record.php?ID=CRD42018091791., (Copyright © The Author(s) 2020.)

The association between the consumption of seafood and its benefits on cardiovascular (CVD) risk can be challenged by its heavy metal (HM) content. This study aimed to explore the association of seafood consumption and its estimated HM contents with the lipid profile and lipid oxidation biomarkers in adults from a Spanish Mediterranean area who do not present risk factors for CVD. In this cross-sectional study, the clinical history, three-day dietary record, lipid profile (LDLc, HDLc, APOB/A, and triglyceride levels), plasma oxidised LDL (oxLDL) and 8-isoprostane levels of 81 adults without risk factors for CVD [43% men, with a mean age of 43.6 years (95%CI: 40.1-47.1)] were assessed. The HM [arsenic (As), cadmium (Cd), mercury (Hg), and lead (Pb)] contents of seafood were estimated according to data from analyses of marine species in the same Mediterranean area. Moderate adherence to the Mediterranean diet (score: 4.6 of 9) with a mean seafood consumption of 74.9g/day (95%CI: 59.9-89.9), including 22.7g of shellfish per day (95%CI: 13.5-31.9), was observed. The estimated HM contents were lower than the provisional tolerable weekly intakes (PTWIs): 21.12µg/kg/week As, 0.57µg/kg/week InAs, 0.15µg/kg/week Cd, 1.11µg/kg/week Hg and 0.28µg/kg/week Pb. After adjusting by confounder variables, an increase in shellfish consumption was associated with increases in the levels of LDLc (P=0.013), non-HDLc (P=0.015), APOB/A (P=0.02) and plasma oxLDL (P=0.002). Moreover, an increase in the estimated As and Hg levels in shellfish was associated with an increase in LDLc (P=0.015 and P=0.018, respectively), non-HDLc (P<0.008 and P<0.008, respectively), APOB/A ratio (P=0.008 and P=0.009, respectively), and oxLDL (P≤0.001 and P≤0.001, respectively) levels. In conclusion, in adults without risk factors for CVD, increasing shellfish consumption, even by a moderate amount, could favour a pro-atherogenic lipid profile and a higher level of oxidised LDL. These associations are likely influenced by the estimated exposure to As and Hg from shellfish despite these values are lower than the PTWIs., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Unlabelled: The objective was to evaluate whether the soluble fibre Plantago ovata (Po)-husk improves cardiovascular disease (CVD) risk biomarkers including low-density lipoprotein cholesterol (LDL-C)., Methods: In a multi-centred, double-blind, placebo-controlled, parallel, randomised trial conducted in primary care-clinics in Spain, France and Holland, mild-moderate hypercholesterolaemic patients (age range: 43-67 years) received 14 g/d of Po-husk (n=126) or placebo (microcrystalline-cellulose 14 g/d; n=128) in a low saturated fat diet for 8 weeks. Subsequently, if LDL-C remained > or = 3.35 mmol/L [130 mg/dL], participants proceeded with the fibre plus simvastatin (20mg/d) for further 8 weeks. Lipid profile, blood pressure (BP), insulin, oxidised LDL and some gene polymorphisms involved in CVD risk were measured., Results: Relative to placebo, Po-husk reduced plasma LDL-C by -6% (P<0.0002), total cholesterol (TC) by -6%, triglycerides (TG) by -21.6%, apolipoprotein (Apo) B-100 by -6.7%, oxidised LDL by a mean of -6.82 U/L (95%CI: 3.15-10.48), insulin by -4.68 pmol/L (95%CI: 0.68-8.67) and systolic BP by -4.0mm Hg (95%CI; 1.2-6.7) (P<0.05). The TG-lowering effect in the Po-husk group was magnified by variants in plasminogen-activator-inhibitor (PAI-1; rs1799768) and fatty acid-binding protein (FABP-2; rs1799883) genes. At 16 weeks, the intra-group action of simvastatin (20mg/d) added to Po-husk or placebo was a similar LDL-C reduction., Conclusions: Po-husk, apart from lowering LDL-C, also reduced TG, TG related to certain gene variants, TC, Apo B-100, oxLDL, insulin-resistance and systolic BP in mild-moderate hypercholesterolaemic individuals. Thus, the target patients to receive Po-husk would be those who present a cluster of various CVD risk factors, such as metabolic syndrome., (Copyright 2010 Elsevier Ireland Ltd.

Two methods based on solid-phase extraction (SPE) using traditional cartridges and microelution SPE plates (muSPE) as the sample pre-treatment, and an improved liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) were developed and compared to determine the phenolic compounds in virgin oil olive from plasma samples. The phenolic compounds studied were hydroxytyrosol, tyrosol, homovanillic acid, p-coumaric acid, 3,4-DHPEA-EDA, p-HPEA-EDA, luteolin, apigenin, pinoresinol and acetoxypinoresinol. Good recoveries were obtained in both methods, and the LOQs and LODs were similar, in the range of low muM. The advantage of muSPE, in comparison with SPE cartridges, was the lack of the evaporation step to pre-concentrate the analytes. The muSPE-UPLC-ESI-MS/MS method developed was then applied to determine the phenolic compounds and their metabolites, in glucuronide, sulphate and methylated forms, in human plasma after the ingestion of virgin olive oil.
