%X Yerba mate has been reported to have antihypertensive, hypocholesterolemic, antidiabetic, or antiobesity properties. Most evidences from human trials involved intakes of high amounts of mate by habitual consumers. Considering its increasing popularity, this study aimed at assessing the potential cardiometabolic effects of moderate intake of yerba mate by nonhabitual consumers. A randomized, crossover, controlled study was carried out in healthy and hypercholesterolemic subjects. Anthropometric parameters, blood pressure, blood lipids, glucose metabolism, inflammatory cytokines, chemokines, and different markers of endothelial function, as well as incretins, adipocytokines, and different hormones were measured at baseline and after 8 weeks consuming yerba mate or a decaffeinated isotonic drink (control). After daily consumption of three servings of mate tea, blood pressure, inflammatory cytokines, chemokines, and colony-stimulating factors decreased in all participants. LDL-C decreased in normocholesterolemic individuals, while the mate and control interventions elicited similar hypolipidemic action in the hypercholesterolemic group. Ghrelin and glucose-dependent insulinotropic polypeptide (GIP) significantly decreased after mate intake, while glucagon-like peptide 1 (GLP-1) and adipocytokines remained unchanged. Body fat percentage and tricipital skinfold decreased only in healthy subjects, with no effects on total body weight. In conclusion, yerba mate could exert cardiometabolic protective effects in healthy consumers and in subjects at moderate cardiovascular risk.
