Therapeutic diets are meal plans prescribed to treat medical conditions. They modify nutrients, textures, or exclude foods due to allergies or intolerances. Common therapeutic diets include diabetic, low-sodium, low-fat, high-fiber, renal, mechanically soft, pureed, and allergen-free diets. Therapeutic diets aim to maintain, restore, or correct nutritional status and are prescribed individually based on a person's medical needs and condition.
