RESUMEN
BACKGROUND: Obesity is an epidemic, multifactorial and difficult-to-control disease, besides being a risk factor for cardiovascular diseases. Among the multiple intervention proposals, the addition of chia in meals has been considered due to its composition and possible effects on weight loss and cardiovascular parameters. OBJECTIVE: We evaluate the influence of chia flour (Salvia hispanica L.) intake on body weight, body composition, energy expenditure (EE) and cardiovascular risk in obese women. METHODS: This study is a clinical trial performed with 20 adult women with obesity randomized into experimental (chia flour) and control (placebo) groups. We assessed anthropometric and biochemical measurements, as well as clinical, dietary and EE variables before intervention and 90 days later. RESULTS: There were no differences in anthropometric indicators, body composition or EE between groups, but a decrease in HDL-c (p = 0.049) and a trend towards the reduction of systolic blood pressure (SBP) (p = 0.062) was observed in the experimental group. CONCLUSION: Chia flour had a possible positive effect on SBP control, but negatively affected the lipid profile and did not seem to influence obesity control.
