NUR 3183 Lecture Notes - Lecture 3: Lactose Intolerance, Dextrin, Blood Glucose Monitoring
Document Summary
Fruits, some vegetables (cabbage, cauliflower, eggplant, and sweet onions), honey, agave, molasses, invert sugar. Describe lactose intolerance its etiology, symptoms, diagnosis and treatment. Etiology insufficient production of lactase which is the only enzyme that digests lactose in the digestive tract. Symptoms intestinal gas and/or cramps, sometimes diarrhea (occurs about 30 minutes to 2 hours after consuming a lactose-rich food(s)) Diagnosis hydrogen (h2) breath test: ingest about 25 to 50 g lactose and monitor h2 gas in the breath (several hours). Gas production increases in breath if intolerant because bacteria are utilizing the undigested lactose and producing h2. Treatment try eating yogurt with active cultures or fermented milk products (bacteria in these foods breaks down some of the lactose) ; take digestive aids - lactaid pills. Mostly formed in the gi tract during starch digestion. Fruits (some) containing sucrose papaya, dates, apricots, pineapple, nectarine, peach, cantaloupe, orange, honeydew melon, bananas, apples, plums, persimmons, and watermelon.
