Document Summary

Rda is 130g/day (amount required by the brain) fruits, dairy, and whole grains consist of cho in their natural, unre ned state re ning carbs reduces nutrient value. Bre delays gastric emptying and makes you feel full small intestine - most carb digestion occurs here. Pancreatic amylase enters intestine from pancreatic duct to digest carbs. Polysaccharides break down into shorter chains and maltose speci c enzymes break down speci c disaccharides (maltase, sucrase, lactase) large intestine - bres in large intestine attract water which softens poo for passage. This creates water, gas and short-chain fatty acids. Bres regulate bowel activity and binds to bile, cholesterol and minerals to leave body. Dietary bre = non digestible carbohydrates that are intrinsic and intact in plants (cellulose) Functional bre = isolated non digestible carbohydrates that have bene cial physiological e ects. Total bre = dietary bre + functional bre.
