The aim of this study was to examine the relationship between sodium and potassium intakes and blood pressure (BP) in a clinical sample. ⋯ In the present study, a high dietary sodium intake and high sodium-to-potassium ratio predicted high SBP. This suggests a need to focus dietary advice on reduction of sources of sodium and increasing sources of potassium in weight loss interventions to improve BP control.

Alcohol addiction elicits oxidative imbalance and it is well known that polyphenols possess antioxidant properties. We investigated whether or not polyphenols could confer a protective potential against alcohol-induced oxidative stress. ⋯ A better understanding of the antioxidant protection provided by polyphenols might be of primary interest for drug discovery and dietary-based prevention of the damage associated with chronic alcohol abuse.

Randomized Controlled Trial Comparative Study Clinical Trial
Inflammatory and metabolic responses to dietary intervention differ among individuals at distinct cardiometabolic risk levels.
The aim of this study was to investigate the effects of two interventions in breakfast with different fatty acid content on metabolic and inflammatory biomarkers in individuals at different cardiovascular risk levels. ⋯ Dietary intervention of small magnitude, for a short period, was able to improve traditional risk factors for cardiovascular disease and inflammatory markers, as well as the frequency of MetS. Responses to dietary interventions of individuals at different levels of cardiovascular risk should be examined through different biomarkers.

The aim of this study was to assess the association between protein and arginine from meat intake and oxidative stress in a general population. ⋯ High protein and arginine from meat intake were associated with oxidative stress independently of genetic, lifestyle, and biochemical confounders in a population-based study. Our results suggested a novel link between high protein/arginine intake and oxidative stress, which is a major cause of age-related diseases.

Multicenter Study Comparative Study
Effect of routine prenatal supplementation on vitamin concentrations in maternal serum and breast milk.
The aim of the present study was to assess the effect of multivitamin supplements and their different vitamin A sources on retinol concentrations in serum and colostrum milk of postpartum women. ⋯ The use of multivitamin supplements containing vitamin A during pregnancy prevents vitamin A deficiency regardless of the source administered. In breast milk, supplementation with β-carotene provided a lower concentration of vitamin A compared with retinol.
