The importance of a low glycemic index

Feeding cats and dogs food that have low glycemic index is important because their metabolism has evolved to gain energy from animal proteins and fats, not carbohydrates. Carbohydrates traditionally found in cat and dog food formulas provide a quick energy burst as postprandial glycemic levels peak which negatively affect insulin and blood sugar controls, provide unwanted calories, and can cause health issues such as obesity and diabetes since their anatomy isn't designed to process them in abundance. Nevertheless, most industrial pet foods on the market contain 40% to 60% cereals which are rich in easily digestible carbohydrates. N&D food lines contain 0% (grain-free) to 20% (low ancestral grain) cereals. 

There are physiologic and pathological conditions where a low sugar level is crucial, and that's why we developed low glycemic index formulas with GMO-free ancestral cereals (spelt and oats) such as Obesity, Neutered, Diabetic, and Joint. In these formulas, a low glycemic index is functional to a moderate postprandial glycemic response and modulation over time.
