EFFECTS OF LOW-COST PROTEIN BARS RICH IN POLYPHENOLS ON DIET QUALITY AND ANTHROPOMETRIC, BIOCHEMICAL, AND OXIDATIVE STRESS PARAMETERS IN SUBJECTS WITH OBESITY

Previous studies have supported the association between intake of phenolic compounds and improvement of obesity parameters. However, most of them are in vitro studies and/or with isolated compounds. This study aimed to examine the feasibility of an approach using enriched phenolic compounds low-cost protein bars on anthropometric, biochemical, and oxidative stress parameters of subjects with obesity. This was a controlled intervention study with a parallel, placebo-controlled, double-blind design. Participants were allocated into two groups, control (n = 9) and treatment (n = 12). Outcomes were assessed at baseline and after the 30-day intervention. No significant changes in the outcomes evaluated were noted between groups. The trial showed acceptable retention rates and adherence to protocol. These results may be useful in the design and implementation of long-term, large-scale studies, contributing to the existing evidence on the beneficial impact of diets with food sources of bioactive compounds on health outcomes.
