The quality of ingredients, rather than just the type of ingredient, can cause food-related allergies in pets. For example, if your dog has a beef allergy it may be the quality of beef they’re eating. Heavy processing changes the molecular structure of ingredients, especially protein. At the molecular level, heavily processed and rendered beef is just not equal to human-grade beef.
The preservatives, additives, and chemicals in pet food can also trigger allergies in your cat and dog. Often, these ingredients are added to make food stay shelf-stable, and serve no nutritional purpose. Fresh, natural petfood removes the need for harmful additives, lowering the chances of triggering a food-related allergy in your pet.
