What is the glycemic index

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.
This is why, after detailed researches, we created N&D "Grain Free", completely without any cereal, and N&D "Low Ancestral Grain", with few ancestral cereals (spelt and oats) which have a lower glycemic index than other cereals commonly used. Their low glycemic index allows a moderate postprandial glycemic response which is also modulated over time. This kind of cereals have a higher dietetic fiber content which helps digestion and nutrient absorption boosting organism's defences.
Using complex cereals such as corn, furthermore, could expose more on GMO contamination risk, which is something against Natural & Delicious nutritional philosophy.

Natural nutrition for a dog or a cat should be almost without carbohydrates as their metabolism evolved to gain Energy from animal proteins and fats. Carbohydrates provide our pets unwanted calories, nevertheless most of the industrial foods on the market contain from 40% to 60% of them.
Carbohydrates in cereals traditionally used in dog and cat food formulas provide a high energy quantity as glucose that induces a quick postprandial glycemic peak. Especially in these cases, postprandial insulin response to glucose and its modulation ability on different types of carbohydrates is crucial.
