A limited ingredient diet is a type of eating plan that focuses on a small number of ingredients. This approach is often used to help identify food sensitivities or allergies, as it reduces the variety of foods consumed. By limiting ingredients, individuals can more easily track their reactions to specific foods. These diets are commonly used for pets, particularly dogs and cats, to manage food allergies or intolerances. Many pet food brands offer limited ingredient diets that contain a single protein source and a few select carbohydrates, making it easier for pet owners to monitor their pets' health and well-being.
