DIGESTION AND ABSORPTION  Your body has to break down all carbs into monosaccharides to absorb it Digestive  enzymes  break down carbs Lactase - enzyme which splits lactose Amylase - enzyme which splits amylose and amylopectin  Dextrins - short glucose polymers produced by digestion of starch. Used as mild  sweeteners and as a carbohydrate source in sport drinks and other foods. Also  called  maltodextrins.  Digestion of carbs stops in the stomach, because stomach acid denatures  salivary amylase. When food arrives in the small intestine, the secretions there  neutralize stomach acid. The pancreas produces another amylase which breaks  down starch to form the disaccharide maltose. Mucosa - cells lining the intestinal tract and responsible for absorption of  nutrients. It produces enzymes that break down disaccharides.

Unformatted text preview: Lactose Intolerance If you dont produce one of these enzymes (or dont produce enough of it), you wont be able to digest and absorb the specific carb that enzyme would digest Unabsorbed carbs pass into the large intestine, where bacteria digest it Bacterial digestion produces acids and gases that irritate the lining of the intestines and cause bloating, diarrhea, cramping, and flatulence The most common enzyme deficiency is lactase insufficiency, which causes lactose intolerance and the other symptoms mentioned above Intolerance may be better or worse, depending on type of dairy products We culture (to ferment foods) dairy products by inoculating them with microorganisms and letting them partially digest the lactose for us...
