Understanding Antioxidants in IAMS™ Dog Food

  • Share

Your dog needs antioxidants to help promote a healthy immune system. This is why every IAMS™ dog formula contains optimal levels of these nutrients.

Antioxidants are important naturally occurring nutrients that help maintain your dog’s health by slowing the destructive oxidative process of cellular molecules. IAMS research is advancing antioxidant nutrients for senior dogs — and the benefit is improved immune function.

Discover how the antioxidants in IAMS products can benefit your dog’s health in a number of ways.

 

The Benefits of Antioxidants

Antioxidants are found naturally in the body and in plants such as fruits and vegetables. Common antioxidants include vitamin A, vitamin C, vitamin E and certain compounds called carotenoids (like lutein and beta-carotene). When antioxidants are part of a dog’s complete diet, they can provide the following benefits:

  • Slowing the oxidative process of cellular molecules
  • Reversing decreases in immune-cell function in senior dogs

 

How Antioxidants Work

As cells function normally in the body, they produce damaged molecules called free radicals. These free radicals are highly unstable and steal components from other cellular molecules, such as fat, protein or DNA, thereby spreading the damage.

This damage continues in a chain reaction, and entire cells soon become damaged and die. This process is called peroxidation. Peroxidation is useful because it helps the body destroy cells that have outlived their usefulness, and it kills germs and parasites. However, when left unchecked, peroxidation also destroys or damages healthy cells.

Antioxidants help prevent widespread cellular destruction by willingly donating components to stabilize free radicals. More importantly, antioxidants return to the surface of the cell to stabilize rather than damage other cellular components.

When there are not enough antioxidants to hold peroxidation in check, free radicals begin damaging healthy cells, which can lead to problems. For example, free radical damage to immune cells can lead to an increased risk of infections.

 

Antioxidants in IAMS Adult Dog and Puppy Foods

Recent research has examined the benefits of certain antioxidants on the immune response of dogs, and the results of these studies indicated that antioxidants are important in helping dogs maintain a healthy immune system.

IAMS adult and puppy formulas contain optimal levels of antioxidants such as:

AntioxidantSourceFunction
Vitamin EPlant oil extract and tocopherolsOptimizes immune system’s T-cell activation
Beta-caroteneVitamin premix, corn meal, chicken by-product meal and chicken fatOptimizes types of cell present in the blood,

    Why Use Wheat in Dog Food?

    Wheat is a grain used as a high-quality carbohydrate source in dry dog foods and biscuits. It provides energy for daily activity, as well as processing characteristics for the food. IAMS™ research has shown that including wheat in a complete and balanced diet results in a moderate glycemic response in dogs, which is lower, in general, than the response observed when a rice-based diet was fed. 1,2

     

    Misconception About Food Allergies

    A common misconception is that feeding wheat causes food allergies. The facts are:

    • The pet must have a hypersensitivity to the food or ingredient. An allergy is an adverse reaction of an individual animal to proteins in the diet.
    • Food allergies are rare in animals and account for a very low percentage of allergic reactions in dogs.
    • If your pet has a food allergy, he is most likely allergic to one ingredient or a combination of ingredients in his diet. In a U.S. study of food-allergic dogs, the two common pet-food ingredients that most often caused an allergic reaction were beef and soy.3

     

    Gluten-Sensitive Enteropathy

    Gluten (a protein found in wheat) is responsible for wheat-sensitive enteropathy, occasionally found in Irish Setters from the United Kingdom. Gluten enteropathy of Irish Setters is a malabsorption syndrome, which responds to the removal of wheat (gluten) from the diet. This condition is very rare, and the reason some dogs develop it is not yet clear.
