The Influence of Plant-Based Diets on Metabolic Syndrome

Abstract

The magnification of Western eating habits has contributed to a large increase in the development of several diseases and conditions, namely cardiovascular disease, obesity, dyslipidemia, and hyperglycemia. These are part of a cluster of metabolic factors involved in metabolic syndrome. However, there are new dietary patterns more focused on the consumption of plant-based foods. Thus, the aim of this review was to investigate the impact of plant-based diets on metabolic syndrome and to achieve the inflammatory mediators and the antioxidant effects involved in this potential health benefits effect. Advanced research was performed for articles published in the last 10 years, which were analyzed and selected according to the defined inclusion and exclusion criteria. Of the articles analyzed, the majority supported the positive impact of plant-based diets on metabolic syndrome. Furthermore, several studies also showed that these diets appear to have an anti-inflammatory and antioxidant role. Thus, plant-based diets appear to have health benefits, contributing to the prevention of metabolic syndrome, and improving the cardiovascular and metabolic markers’ profile, mainly when including healthy foods. The total exclusion of animal source foods (especially meat and fish) from the diet, as well as the consumption of processed and additive plant-based foods, may contribute to an increased prevalence of metabolic syndrome.
