carbohydrate intolerance

Carbohydrate intolerance is the inability of the body to completely process the nutrient carbohydrate (a classification that includes sugars and starches) into a source of energy for the body, usually because of the deficiency of an enzyme needed for digestion. Lactose intolerance , the inability to digest the sugar found in milk, is widespread and affects up to 70% of the world's adult population.
