Metabolic syndrome is a cluster of conditions including hypertension, central obesity, dyslipidemia, and insulin resistance that increase the risk of cardiovascular disease and type 2 diabetes mellitus. Dietary patterns have emerged as modifiable risk factors, with plant-based diets gaining attention for their potential protective effects. Plant-based diets, when composed of minimally processed and nutrient dense foods, may offer a protective role against metabolic syndrome. In addition to nutrition science, religion and cultural practices play a significant role in shaping dietary behaviors. Specifically, many religious and cultural traditions promote plant-based eating, fasting, or the avoidance of certain animal products, which may aid metabolic health. Understanding this influence is essential for developing culturally sensitive dietary recommendations and for recognizing the broader social and spiritual dimensions of food choices. The intent of this paper is to examine the health impacts of plant-based dietary patterns, as related to both religious or cultural practices and norms.
