What are carbohydrates for?

Carbohydrates, in the form of starches and sugars, are the main fuel for our body which required in the largest amounts. It is recommended that carbohydrates should supply 45–65% of our total daily energy needs.

The brain, kidneys, muscles and heart all need carbohydrates to function properly, and carbohydrates aid in the synthesis of certain amino acids. Furthermore, fats can only be properly metabolized when carbohydrates are present and indigestible carbohydrates, in the form of dietary fiber, are necessary for intestinal health.

Glycemic index, GI, is calculated based on how quickly carbohydrates in food lead to an elevation of your blood sugar. The faster carbs rank in a food digest, the higher the glycemic index; the slower they rank, the lower the GI.

Regular consume can keep your blood sugar elevated and causing weight gain and elevated risk of type two diabetes, metabolic and cardiovascular diseases.
