This carbohydrate is easily decomposed into monosaccharides during digestion, and then quickly absorbed into the blood, leading to an increase in blood sugar. Simple carbohydrates are usually found in fruits, juices, sweets, white rice, white bread and other foods.

Complex carbohydrates, also known as slow carbon.

In the process of digestion, these carbohydrates need to be decomposed into monosaccharides by the action of enzymes, and then slowly absorbed into the blood, thus producing stable blood sugar. Complex carbohydrates usually exist in coarse grains, beans, vegetables and other foods.
