All figures from the carbohydrates lecture slides, k. ng, semester 1 2017, melbourne university (unless stated) Digestion: the human body secrets enzymes to digest the polymers, e. g. for starch it is amylase, for lactose is lactase. Fermentation: bacteria releases the enzyme sin the colon. Glycaemic response is how quickly the blood glucose rises and elicits an insulin response. Glycaemic index (gi) classifies foods according to their potential for raising blood glucose: as per 50g carbs. Glycaemic load refers to a food"s gl(cid:455)(cid:272)ae(cid:373)i(cid:272) i(cid:374)de(cid:454) a(cid:374)d the a(cid:373)ou(cid:374)t of carbohydrate the food contains. Feeds 10 or more healthy people a food containing 50g of carbs: can be liquid or solid (e. g. bread) Measures blood glucose levels over the next two hours every 30 mins: area under curve. When an individual cannot digest the lactase, main sugar of milk. Causes include lactase deficiency that can occur with aging or damaged intestinal villi: can be genetical, age increases so lactase production decreases.
