Relationship between cardiometabolic profile, vitamin D status and BsmI polymorphism of the VDR gene in non-institutionalized elderly subjects: Cardiometabolic profile, vitamin D status and BsmI polymorphism of the VDR gene in non-institutionalized elderly subjects.

This study aimed to evaluate the relationship between the cardiometabolic profile, vitamin D status and BsmI polymorphism of the VDR gene in non-institutionalized elderly subjects. A cross-sectional study was conducted with a random and representative sample of 142 elderly subjects selected by cluster and recruited from a municipal assistance program. Clinical, nutritional, biochemical and inflammatory profiles, oxidative stress and genotyping for the BsmI polymorphism were evaluated.

Watermelon extract reduces blood pressure but does not change sympathovagal balance in prehypertensive and hypertensive subjects.

Previous studies have shown that watermelon extract reduces blood pressure through vasodilation. However, those studies have not verified whether sympathetic nervous activity is influenced by watermelon extract. This study aimed to evaluate the effect of supplementation with watermelon extract for 6 weeks on blood pressure and sympathovagal balance of prehypertensive and hypertensive individuals.

Potential ergogenic activity of grape juice in runners.

Recent studies have indicated that certain food products have ergogenic potential similar to that of sports supplements. The present study aimed to investigate the potential ergogenic effect of integral purple grape juice on the performance of recreational runners. Twenty-eight volunteers of both sexes (age, 39.

Chia flour supplementation reduces blood pressure in hypertensive subjects.

The aim of this study was to investigate the effect of chia supplementation (Salvia hispanica L.) on blood pressure (BP) and its associated cardiometabolic factors in treated and untreated hypertensive individuals. The subjects were randomly assigned to one of the following groups: the hypertensive-drug treated (CHIA-MD, n = 10), hypertensive untreated (CHIA-NM, n = 9) and placebo (PLA-MD, n = 7) groups.

Supplementation prevalence and adverse effects in physical exercise practitioners.

Introduction: The use of nutritional supplements is prevalent among physical exercise practitioners and some adverse effects have been reported, however not sufficiently substantial, because they originate from isolated cases.

Objectives: Investigate nutritional supplements consumption prevalence and adverse effects of the use of such products.

Methods: An epidemiological, representative and transversal study, with 180 physical exercise practitioners in gyms, who answered questionnaires about sports supplementation, associated factors and self-perceived adverse effects.

Chia induces clinically discrete weight loss and improves lipid profile only in altered previous values.

Introduction: chia (Salvia hispanica L.) has an elevated concentration of dietary fiber, it has been used to weight loss and enhance blood glucose and lipid profile. However, data in human are still scarce or do not exist, according to the analyzed variable.
