Therapeutic diets are meal plans designed to control specific food or nutrient intake for medical treatment, tailored to individual nutrition needs. These diets are often prescribed by physicians and may include modifications for common issues like food allergies, intolerances, and nutritional deficiencies. Common types include nutrient modification diets (e.g., low sodium, high fiber), texture modification diets (e.g., pureed diets), and tube feedings for those unable to eat orally.
