For a cat health food is food that is high in protein and low in carbohydrates because a cat in the wild would eat no carbs. Unfortuntaly most cat foods are very high in carbs and also contain high amounts of preservatives and "waste" from meat plants. It is commonly thought among experts in the field that the poor quality of most cat food is the biggest cause of illnesses and early death among cats. Cat's bodies are not made to digest the type of material that is found in most cat foods that's why it's worth the extra money to buy high quality cat food. The extra money you spend on high quality healthy cat food will end up being less money than you have to spend at the vet trying to take care of your sickly cat.
