Aspartame 1) Equal, NutraSweet 2) Composed of phenylalanine, aspartic acid, and methanol 3) 180-200x sweeter than sucrose 4) 4 kcal/gm 5) Not heat stable - damaged 6) Complaints of sensitivity: Headaches, dizziness, seizures, nausea, etc. 7) Acceptable daily intake: 50 mg per kg body weight (FDA) (~14 cans of diet soda for average adult per day) 8) Warning label for Phenylketonuria (PKU) Does type of CHO matter? Glucose: preferred energy source Fructose: absorbed more slowly from gut, but does not "spare" muscle glycogen any more than glucose and high amounts lead GI distress Glucose polymers: Chains of glucose molecules shorter than starch but longer than simple sugar derived via partial hydrolysis of polysaccharides GP solutions empty from stomach more rapidly than starch, less rapidly than simple sugar often sold as supplement since they provide glucose and fuel Studies do not reveal significant difference in exercise performance from different CHO sources Recommendations: CHO for prolonged exercise Four hours prior to performance a. 4-5 grams/kg b. Fiber should be minimized One hour prior to performance a. 1-2 grams/kg b. Glucose polymers or foods with low glycemic index Immediately before exercise, 50-60 grams of glucose polymer in a 40-50% solution During exercise, feedings every 15-30 minutes of a 5-10% solution containing 15-20 g CHO CHO replenishment after prolonged exercise Repeated prolonged exercise tasks with 4 hour interval: Consume 1 gram carbohydrate per kg immediately after the first event and again 2 hours prior to the second event A combination of protein and carbohydrate induced faster glycogen re-synthesis Carbohydrate/creatine combination?

The minimum amount of carbohydrates needed daily is a. 75 grams. b. 100 grams. c. 120 grams. d. 130 grams. e. 150 grams. (d) The DRI for carbohydrate is to consume at least 130 grams daily. This is the minimum amount needed to supply the glucose that the body, particularly the brain, must have to function effectively. The primary lipid(s) in the body is (are) a. cholesterol. b. lecithin. c. triglycerides. d. chylomicrons. (c) Triglycerides, also known as fat, are the most abundant lipids in foods and in the body. Cholesterol is another type of lipid but is not as abundant as fat. Lecithin is a phospholipid found in cell membranes and is used as an emulsifier in some foods. Chylomicrons are lipoproteins that transport fat and other lipids to the liver. Trans fats are a double threat for the heart because they a. raise the "bad" LDL cholesterol and lower the "good" HDL cholesterol in the body. b. raise the "good" HDL cholesterol and lower the "bad" LDL cholesterol in the body. c. raise the "bad" LDL cholesterol and raise the "good" HDL cholesterol in the body. d. lower the "good" HDL cholesterol and lower the "bad" LDL cholesterol in the body.

Sort List of carbohydrates for classification; which of these has the sweetest taste? Will this sugar offer a Caloric/sweet taste advantage used in cooked foods? Which of these binds cholesterol in the gut? Which of these is stored in the liver? -lactose, galactose, sucrose, starch, maltose, cellulose, glucose, fructose, glycogen -fructose is sweetest, yes -fiber (cellulose) Define 'impaired glucose tolerance' and '2 hour post prandial.' Be able to describe when they are used. -impaired glucose tolerance = pre-diabetic state of hyperglycemia->excessive amount of glucose circulates in the blood plasma -a postprandial glucose test is a blood glucose test that determines the amount of a glucose in the blood after a meal -a 2 hour post prandial measures blood glucose exactly 2 hours after eating a meal, timed from the start of the meal -by this point blood sugar has usually gone back down in healthy people, but it may still be elevated in people with diabetes -thus, it serves as a test of whether a person may have diabetes, or of whether a person who has diabetes is successfully controlling their blood sugar Define glycemic effect. Discuss the controversy related to usefulness of glycemic index. glycemic response= how quickly glucose is absorbed after a person eats, how high blood glucose rises, and how quickly it returns to normal -opposition to use of glycemic idex argue that it is not sufficiently supported by scientific research; values vary because of differences in the physical and chemical characteristics of foods, testing methods of laboratories, and digestive processes of individuals -practical utility of GI is limited bc info is neither provided on food labels nor intuitively apparent Jen skips breakfast.

Ketosis

Ketosis

Sort what is the mechanism behind ketosis cows make energy with the acetate , butyrate and propionate excessive fat mobilisation so can get into krebs cycle to get energy ( in a normal animal ) normally fat depot is turned into free fatty acids - then into acetyl CoA then goes into glucose drived precusor OAA -and then enter the kreb cycle if there is insuffient substrate ( OAA )- propionate ( not eating enough) or ( OAA ) excess drianage into the glucose in milk ( high producing cows , not that often in jersey) then the acetly CoA will not be able to enter the kreb cycle , instead it will produce ketones primary ketosis when does it occur? primary underfeeding ketosis - when the cow is not being fed with adequate amount of feed therefore insufficient propionate precusors are available ( diet not containing not wt it needs to ) - not enough energy in the det - not enough gluconeogenic precursors ( propionate ) in diet occur:4- 6 weeks post calving ( during peak lactation ) - before they calve - low energy diet ( they cant fit in , causing metabolic problems ) - calved -- going to lactate so need a lot more energy , feed them more ( from the feeding ) dry cow : on maintenance diet secondary ketosis secondary underfeeding ketosis - then the cows vluntary intake is being inhibited by another disease - leading to insufficient intak of proprionate precursors disease include - left displaced abdomen ( top of the list ) - lamness - post-partum infection common in first calver : - check their mouth - teeth erupting --painful -> dont wanna eat NOte : if a ketosis is being suspected with no obvious reason or just one -off ketosis - then need to do throughout abdominal ping exam - to check for LDA although it is common for cows that are down with post-partum recumbency, maybe due Continue reading >>
