A dietary group refers to a category or classification of foods that share similar nutritional characteristics, such as being high in protein, low in fat, or containing specific vitamins and minerals. These groups are often used by healthcare professionals, nutritionists, and dietitians to help individuals make informed choices about their eating habits based on their unique needs and goals. For example, a person following a vegetarian or vegan diet may belong to the "dietary group" of plant-based eaters, while someone with high blood pressure might be advised to follow a diet that is low in sodium, which would place them in the "low-sodium dietary group."
