Corn overload in food may be killing cats, humans

Corn, cornmeal, corn gluten, cornstarch and corn syrup are cheap ingredients in a host of processed human and pet foods.

The high corn- and corn-byproduct content of many pet foods is a concern, and I believe it contributes to the high incidence of diabetes in dogs and cats. Plus, many cats are allergic to corn, and inflammatory bowel disease is one possible consequence.

You ask how pet-food manufacturers can ''in good conscience, tout their product as being healthy.'' The same question can be asked of human-food companies. Just look at the sugar-loaded breakfast cereals. ''Good conscience'' and corporate profits are so disconnected that I advocate greater consumer responsibility, as per my book Eating With Conscience: The Bioethics of Food (New Sage Press, 1997). And that goes for what we feed all our family members -- four-legged as well as two-legged.
