Abstract

Soy protein contains beneficial components like complex carbohydrates, unsaturated fatty acids, vegetable protein, soluble fiber, oligosaccharides, vitamins, minerals, inositol-derived substances and phytoestrogens, particularly the isoflavones genistein, diadzein, and glycitein, which might affect different cardio-metabolic abnormalities. Soy consumption has been reported to beneficially affect features of the metabolic syndrome in animal models and also in humans to some extent. There are inconsistent reports regarding the hypothesis of the effectiveness of soy protein on obesity. While some studies have shown that soy consumption can improve the features of the metabolic syndrome without affecting body weight, others showed that soy consumption has beneficial role in weight management and might improve the metabolic syndrome by affecting body weight control. Several studies have consistently reported the effects of soy on cardiovascular risks. Beneficial role of soy intake on diabetes is another aspect of soy inclusion in the diet. The present study discusses the effects of soy consumption on different cardio-metabolic abnormalities and provides information regarding the possible mechanisms by which soy protein might exert its beneficial roles.
