Eating a variety of foods supports health by ensuring that the body receives the necessary vitamins, minerals, and nutrients it needs to function optimally. A diverse diet can help prevent nutrient deficiencies, ultimately contributing to better immune function and reduced risk of chronic diseases. Additionally, different foods offer varying benefits, such as antioxidants from fruits and vegetables, healthy fats from nuts and seeds, and protein from lean meats and legumes. This balance promotes overall health and supports a well-rounded diet.
