Corn is found in many cat foods — but not all corn is created equal. Learn more about this ingredient, its forms and its role as a source of energy for your cat.
Corn is included in cat food formulas in various forms, such as ground corn, corn meal, corn grits, corn gluten meal and corn bran. When reviewing the ingredients list on cat food packaging, you may see one or more of the following corn ingredients:
Corn Ingredient | What It Is |
Ground corn or corn meal | Finely ground and chopped whole corn |
Corn grits | The portion of ground corn containing little or none of the bran (fiber) or germ (the small protein portion at the end of the kernel) |
Corn bran | The outer coating of the corn kernel; largely fiber |
Corn gluten meal | A dried protein source that remains after the corn’s bran has been separated and removed and a large portion of the carbohydrate and germ have been removed |
Corn is included in the formulas for all IAMS cat foods, including IAMS™ ProActive Health™ Healthy Adult and ProActive Health™ Healthy Kitten. It is more appropriate to associate the corn used in our products with “corn bread” rather than “corn on the cob.” The difference is similar to cooked corn versus raw corn. We use only the highest-quality corn in our products. The corn is finely ground to a meal, which breaks up the outside covering of each kernel, and then it is cooked, which increases its digestibility.
Corn grits and corn meal are used in our foods as high-quality sources of carbohydrates, which are an important source of energy. Corn generally also results in lower glycemic and insulin response than rice. This can be especially beneficial for senior and overweight cats.
Nutrients such as protein, fat, vitamins, and minerals are important players in the skin and coat health of dogs and cats. To understand their role, it is necessary to first understand skin and hair.
The purpose of skin and hair is to block things (such as water or heat) from leaving, or things (such as viruses and bacteria) from entering the body.
The hair coat is composed almost entirely of protein. If an animal's diet doesn't contain adequate protein quantity and quality, hair may fall out, or become dry, weak, and brittle.
Skin is made up of squamous cells, which are flat cells tightly packed together. These cells have tough membranes that are composed of proteins and fats. Without proper amounts of these nutrients, cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Proteins are found in both animal-based and plant-based ingredients. Animal-based proteins contain all the essential amino acids cats need, whereas plant-based proteins may contain only some essential amino acids. Cats need animal-based proteins to achieve optimal health.
Fats also can be found in both animal-based and plant-based ingredients, and they are incorporated into skin cells as fatty acids. There are two essential fatty acids for skin and coat health. Linoleic acid maintains skin and coat condition in dogs and cats. Without enough linoleic acid cats may experience dull, dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation. Cats also require arachidonic acid for normal skin and coat health.
Both of these essential fatty acids are omega-6 fatty acids and are found in animal tissues such as chicken fat. Linoleic acid is also found in some vegetable oils, such as corn and soybean oils. Most commercial cat diets contain more than adequate amounts of omega-6 fatty acids.
Because these fatty acids can be converted to compounds that increase susceptibility to skin inflammation, it is important to balance the amount of omega-6 fatty acids in the diet with omega-3 fatty acids, which do not reduce susceptibility to inflammation.
Omega-3 fatty acids are found in oils from fish and some plants (canola and flax).
IAMS™ research has found that combining fat sources in the diet at a ratio of five to 10 omega-6 fatty acids to one omega-3 fatty acid results in excellent skin and coat health.
Vitamins and minerals are essential for the development of healthy skin and hair coat. The best way to provide these nutrients is through a complete and balanced diet containing appropriate amounts of essential vitamins and minerals rather than through supplements.
Vitamin or Mineral | Important for Skin and Coat Health |
Vitamin A | Necessary for growth and repair of skin |
Vitamin E | Protects skin cells from oxidant damage |
Biotin | Aids in the utilization of protein |
Riboflavin (B2) | Necessary for fat and protein metabolism |
Zinc | Necessary for fat and protein metabolism |
Copper | Involved in tissue, pigment, and protein synthesis |
Diet is often believed to be a factor when changes in skin and coat condition are noticed. The most common causes of these changes, however, are season and life stage.
As cold weather approaches, most dogs and cats grow a thick coat to help keep heat in and cold air out. As the weather begins to warm up, they shed the thick, heavy coat.
Most kittens are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or lactating cats also may experience a change in coat condition or hair loss.
