Document Summary
Module 3 high fat, low fat, no fat . Researchers believe and have showed that the lecithin in soybeans may help to decrease cardiovascular disease risk by inhibiting cholesterol absorption and promoting cholesterol excretion from the body. We obtain omega-6 fatty acids from food such as nuts, seeds, and vegetable oils: omega-3 polyunsaturated fatty acids (alpha-linolenic acid) is needed to synthesize epa and dha. These fatty acids are needed for optimal cardiovascular system function, platelet function, endothelial cell function and nervous system development and health. Major sources of alpha-linolenic omega-3 fatty acids include walnuts, flaxseed, canola oil and soybean oil, and fish is a major source of epa and dha. That is, when triglycerides are made of fatty acids with longer chains (more than. 14 carbons), there is less oxidation (burning) of fat compared to short and medium chain fatty acids: this means that the longer chain triglycerides may be more likely to put in storage in adipose tissue.
