Effect of ingestion of mate tea and chocolate in the endothelium of individuals with HIV / AIDS

INTERVENTION: Individuals are supplemented with 65g chocolate bars containing cocoa 36g and 300 mL of mate tea. As placebo tablets were formulated without cocoa and 300 mL of prepared liquid with similar appearance and aroma to the mate tea. The whole intervention period is 105 days divided into four phases, each of which lasts 15 days, followed by a washout in the same time. In phase I, 180 subjects were randomized to ensure the receipt of one of four possible supplementation in phase II will be held in rotation supplementation, the same occurring in stages III and IV, thus ensuring that all volunteers participate in the four treatments. Supplementation is daily and membership is confirmed by personal contact or telephone. CONDITION: ; AIDS, HIV‐positive patients, HAART, Cocoa, Endothelial function, Tea ; ; PRIMARY OUTCOME: Assessing the impact of eating chocolate and mate tea on endothelial function and vascular elasticity of patients with HIV / AIDS. SECONDARY OUTCOME: 1. Assessing the impact of supplementation with cocoa and mate tea in inflammatory parameters; ; ; 2. Assessing the impact of supplementation with cocoa and mate tea in the biochemical parameters including lipid profile; ; ; 3. To evaluate anthropometric measurements before and after intervention. INCLUSION CRITERIA: Individuals of both sexes aged 19 to 59 years with HIV / AIDS and who were on regular treatment with HAART for at least six months.
