The main food sources of carbohydrates are: sugar, grains (e.g., rice, wheat, corn, barley, oats, sorghum, etc.), fruits (e.g., sugarcane, melons, watermelons, bananas, grapes, etc.), dried fruits, dry legumes, and root vegetables (e.g., carrots, fava beans, etc.).

Carbohydrates are the main component of the cellular structure of life and the main energy-supplying substances, and have an important function in regulating cellular activity. There are three main forms of carbohydrates in the body, glucose, glycogen and sugar-containing complexes, and the physiological functions of carbohydrates are related to the types of carbohydrates in the food they consume and the forms they exist in the body.

Expanded Information:

The main source of dietary carbohydrates is plant foods such as cereals, potatoes, root vegetables and legumes, in addition to edible sugars. Carbohydrates can only be absorbed if they are digested and broken down into glucose, fructose and galactose, which in turn are converted to glucose by the liver.

The glucose in the blood is referred to as blood glucose, a small portion of the blood glucose is used directly by the tissue cells to react with oxygen to generate carbon dioxide and water, releasing heat for the body to need, most of the blood glucose exists in the body's cells, if the cells are saturated with glucose stored in the cell, the excess glucose will be stored in the form of high-energy fats, eat more carbohydrates to get fat is this reason!
