Intestinal absorption of carbohydrates in man

Carbohydrates provide about half the total calories in the diet of the average household in this country (Greaves & Ilollingsworth, 1964).Typically, nearly twothirds of this ingested carbohydrate are derived from starch, about a quarter from sucrose and about a tenth from lactose.All this carbohydrate is hydrolysed to monosaccharides prior to absorption, producing approximately 250 g glucose, 40 g fructose and 10 g galactose.
