"Limited ingredient" refers to products, often in the context of food or pet food, that contain a small number of ingredients. This approach is designed to simplify the ingredient list, making it easier for consumers to identify what they are consuming. It is particularly popular among those with dietary restrictions or allergies, as fewer ingredients can reduce the risk of adverse reactions. In the pet food industry, limited ingredient diets are formulated to help pets with sensitivities or allergies. These diets typically focus on a single protein source and a few select carbohydrates, allowing pet owners to monitor their pet's reactions more effectively.
