The effects of a carbohydrates source on glycemic level is provided by the Glycemic Index. Foods with a low Glycemic Index are better assimilated, as their absorption time is modulated, hence there is a reduction of physical stress and consequent efficiency raise.
A high Glycemic Index, linked to cereals rich in starch highly digestible, predisposes to pathologies such as obesity and diabetes, both in human and animal.
There are phisiological and pathological conditions where a low sugar level is crucial and that's why we developed some low glycemic index formulas with GMO free ancestral cereals (spelt and oats): Obesity, Neutered, Diabetic, Joint. In these formulas low glycemic index is functional to a moderate postprandial glycemic response better modulated over time.
