Document Summary
Low fat diets: didn"t work in the 80s. Need time to adjust to taste of low-fat diet: flavorful fruits, vegetables. Replace whole milk with 1% or skim: in time, whole milk will taste too creamy. Benefits: weight control, reduced risk of chronic disease. Breakdown of the c=c bonds by uv light, and/or o2. Section 5. 4: making lipids available for body use. Hormone cholecystokinin (cck: stimulates release of pancreatic lipase. Bile acid released: emulsifies digested fat. Fat is broken down: to monoglycerides and fatty acids in watery digestive juices. Enzymes released: from pancreas, from cells of the small intestine. Broken down to: glycerol, fatty acids, remaining parts. Lipoprotein lipase: breaks down triglycerides in the chylomicrons, chylomicron remnant. Water and oil (fat) do not mix easily. Unique system of fat transportation is needed. Lipoprotein compound in bloodstream containing a core of lipids with shell composed of protein, phospholipid, and cholesterol: vehicle used for lipid transport.
