Corn: the real culprit?
When it comes to ingredients in petfood, no other is more controversial than corn. It has been called a filler, a "hot grain" and a major cause of allergies in dogs and cats.
But many petfood producers say corn is a natural and wholesome ingredient that supplies essential fatty acids, protein, carbohydrates and antioxidants. In addition, according to a Hill’s Nutrition review of published literature, corn was implicated in fewer allergy cases than common protein sources such as beef, dairy products, wheat, chicken, egg, lamb or soy. According to recent studies in various species, antioxidants in foods such as corn may potentially reduce the risk of some forms of cancer, heart disease, arthritis, strokes, atherosclerosis, cataracts and slow the aging process.
While some argue corn provides no essential nutrition and is indigestible for animals once cooked or ground, others say corn is a rich source of fatty acids, for healthy skin and coat, and carbohydrates supplied by corn are an important source of energy.
