You are correct, we do not believe starches should be a mainstay of human or pet diets.
With that said, we also do not believe one need be a purist to achieve health. See the Optimal Health Program
As a part of a varied diet, starch sources can be consumed with benefit and little harm if they are in theIR best form--such as whole grains, as in the rice you mention and in the whole grains used in many of our products.
Since whole grain products are hard to obtain locally for some people, we offer them as a convenience.
