HOW THE BODY MAINTAINS BLOOD GLUCOSE LEVELS

SOURCES OF CARBOHYDRATES

FUNCTIONS OF CARBOHYDRATES Provides energy to the body to carry out day-to-day work

and maintain body temperature. When blood glucose levels fall, the brain does not receive

energy and convulsions may occur. Carbohydrates spare proteins from being broken down for

energy and are used for bodybuilding and repair. They are required for complete oxidation of fat. They can be converted into non-essential amino acids. The sugar lactose helps in the absorption of the minerals

calcium and phosphorus. Lactose helps certain bacteria to grow in the intestine. Dietary fibre plays an important role of increasing faecal

mass. Fibre also helps in lowering blood cholesterol levels.

EFFECTS OF EXCESS CARBOHYDRATE CONSUMPTION

Can lead to dental caries or tooth decay Depresses the appetite, provides hollow calories,

and could result in malnutrition Can increase the blood triglyceride levels leading

to heart diseases Can lead to obesity Can irritate the intestinal lining, causing cramps or

bloating Excessive fibre interferes with the absorption and

availability of mineral elements such as iron and calcium
