Diet research focuses on the impact of different types of diets on human health and well-being. This includes studying the effects of specific nutrients, food groups, and eating patterns on factors such as weight management, chronic disease prevention, and overall quality of life. Researchers may investigate the benefits of diets such as the Mediterranean diet, plant-based diets, low-carb diets, or intermittent fasting, among others. The goal of diet research is to provide evidence-based recommendations for individuals looking to improve their health through dietary changes.
