Fat free, gluten free, and now grain free foods line the shelves of grocery and pet food stores. Millions of dollars are spent on advertising by multi billion dollar corporations to convince us that this is the true path to health and wellness for ourselves, our families and our beloved animals. Removing fat, gluten and grain from our diet and that of our animals has increased the incidence of obesity and diabetes. This is due to the substitution of soluble carbohydrates for fat, gluten and grain. Grain free describes pet food free of corn, soy, wheat, barley, or oats. The grains have been replaced with soluble carbohydrates or starches found in potatoes, rice, peas, lentils and other legume seeds.
