Abstract

The increasing incidence of metabolic diseases, which include obesity, insulin resistance, and type 2 diabetes, has led to an increasing need for complementary therapies to address these health issues.Functional foods, which contain bioactive compounds such as polyphenols and omega-3 fatty acids, have been shown to have beneficial effects on metabolic health, including the treatment of obesity and diabetes.This introduction explores the potential of functional foods to prevent or treat metabolic diseases by examining the impacts of certain bioactive chemicals on important metabolic health pathways present in these foods along with some recent approaches like nutrigenomic and the interaction of bioactive compounds of functional foods to treat metabolic disorders by altering gene expression.Through an examination of the scientific literature authored by a range of writers, we are able to identify the many viewpoints and continuing investigations that highlight the importance of functional food within the current nutritional context.
