We are often presented with concerns about corn being in pet foods. Clients often referring to it as “just a filler” with “no nutritional value”. In fact corn is a highly nutritious ingredient. Corn is chosen as a source of protein (for muscle and tissue growth), carbohydrates (for energy), fiber, antioxidants (Beta-carotene, Vitamin E, Lutein) and linoleic acid (an essential fatty acid that promotes healthy skin and a luxurious coat).
Veterinary diets (Medi-Cal Royal Canin and Hill’s Prescription Diets) use grades 1 and 2 corn, which are the grades traditionally used for human food products. Typically corn is seen on the ingredients list as corn or corn meal. Most grains, including corn, are poorly digested before they are cooked. Once cooked, however, they become highly digestible. Corn has a higher digestibility than several other grains such as rice, wheat, and barley.
While some individuals are concerned about allergies in pets, corn is NOT a common cause of adverse food reactions in pets. Studies have shown that corn causes no more food allergies than any other grain.
If you are every confronted by myths about corn… you heard it here: “Actually corn is not a filler. Corn is great source of protein, carbohydrates, fibre, antioxidants and fatty acids.”
