Indeed, switching your pet to a low-carb diet might even be depriving him of nutrients he needs.
"Whole grains contain valuable dietary nutrients, including vitamins, minerals, essential fatty acids and fiber," Cailin Heinze, a veterinary nutritionist at Cummings Veterinary Medical Center, wrote recently. "The vast majority of dogs and cats are very efficient at digesting and using more than 90 percent of the nutrients from grains in the amounts typically found in pet foods."
So while we humans may try to deprive ourselves of the carby foods we love, our pets probably don't have to. And why should they? They already get pretty much whatever they want anyway.
