What is the difference between hypoallergenic food and a health food?

A characteristic of hypoallergenic diets is that these consist out of one carbohydrate source and one protein source. Hypoallergenic diets are often formulated with more exclusive and unique ingredients. For example: Hypoallergenic (Rabbit) contains the protein source rabbit and carbohydrate source rice. A maintenance food such as Adult or Sterilised is not suited as hypoallergenic diet. Healthy pets can always be fed a hypoallergenic food, but a patient with food allergy cannot always safely be fed a ‘regular’ food.
