, a highly cited interdisciplinary scientific journal, recently announced the discovery that novel adaptions allowing early ancestors of modern dogs to thrive on a starch-rich diet was a key step in the dog’s evolution from the wolf. The idea that dogs have evolved to eat starches – a carbohydrate fraction found in foods like wheat, corn and potatoes – is making waves among pet owners, as well as within the scientific community. Why? It challenges the rising belief that dogs should eat a limited diet, one that doesn’t include carbohydrate sources like wheat and corn.
The belief that dogs shouldn’t eat starches has always perplexed the nutritionists at Purina, as our decades of research have consistently suggested the opposite. We even recently came out in support of the role of grains in a dog’s diet
. Now, there is genetic proof that dogs evolved to eat grains.
