Document Summary

Soy protein lowers ldl cholesterol, high in polyunsaturated fat. Nuts are high in monounsaturated fat, omega 3 fatty acids, antioxidants and fibre. Fish contain omega 3 fatty acids, epa and dha. The primary type of lipid in our body is triglycerides; two other types are phospholipids and sterols. Triacylglycerol consist of a backbone of glycerol with 3 fatty acids attached. Fatty acids consist of a methyl end and an acid group. Monounsaturated fatty acid has 1 c=c double bond, polyunsaturated has 2 (omega-6), polyunsaturated (omega 3) has 3 c=c. Saturated fatty acid when carbon chain is bound to 2 hydrogens and is saturated with hydrogens. Most common monounsaturated fatty acid is oleic acid. Omega 3: the double bond occurs between the 3-4 carbon. Omega 6: the double bond occurs between the 6-7 carbon. Replace saturated fats with polyunsaturated fats as well as increase i(cid:374)take of o(cid:373)ega 3 s.
