Carbohydrates are also known as saccharides or sugars. The GI (Glycemic Index) measures how quickly a carbohydrate is absorbed into the bloodstream. The carbohydrate with the highest GI is refined sugar, like the kind found in sweets or added to coffee.
In general, most carbohydrates are good and fast sources of energy. One gram of carbohydrate provides 4 kilocalories (the same as protein). Fats, by comparison, are more energy-dense, providing 9 kcal per gram.
Carbohydrate Intake
