Dietary soya lecithin decreases plasma triglyceride levels and inhibits collagen- and ADP-induced platelet aggregation.

Brook JG, Linn S, Aviram M.

Elevated plasma lipid concentrations and increased platelet activation are risk factors in the development of atherosclerosis. Nine patients with type IIa hyperlipoproteinemia and nine patients with type IV hyperlipoproteinemia were given soya lecithin, 12 g/day, for 3 months. Plasma cholesterol and triglycerides were reduced by 15 and 23%, respectively, and HDL-cholesterol increased by 16% in the hypercholesterolemic patients. Platelet function was unchanged. In the hypertriglyceridemic patients, total cholesterol fell by 18%, triglycerides by 36%, and HDL-cholesterol increased by 14%. There was a 27% reduction in platelet aggregation (P less than 0.01). Seventeen hypertriglyceridemic patients then received increasing doses of soya lecithin for 1-month periods (6, 12, and 18 g/day). The optimal lipoprotein-lowering effect was achieved with a daily dose of 12 g soya lecithin per day. Both low-density lipoprotein and very-low-density lipoprotein levels were reduced, and HDL-cholesterol and apolipoprotein levels were reduced, and HDL-cholesterol and apolipoprotein A-I concentrations were increased. Platelet aggregation in response to collagen and ADP was significantly reduced, parallel with the reduction in triglyceride level. Soya lecithin supplementing the diet may be useful in the management of the hypertriglyceridemic patient . [LOWERS CHOLESTEROL]

Soyabean phospholipids, particularly commercial lecithin, are now widely used as biological active food additives. Mechanisms of their activities are based mainly on their similarity with ow phospholipids of biomembranes and blood lipoproteins. The similarity allows the inclusion of plant phospholipids into these structures and promotes prevention of number of pathological processes. Soybean phospholipids have a wide range of biochemical and physical effects. Lecithin complex is the source of easily accessible linoleic acid, choline and inositol. Lecithin plays a notable role as synergist for antioxidants also. The proven health benefits which can be achieved by taking soybean phospholipids include lipid-lowering; control of blood levels of cholesterol and triglyceride, stabilisation of the membrane functions, supporting the hepatic functions . Structure, some physico-chemical properties and metabolism of phospholipids, and molecular mechanisms of their prophylactic effects are briefly reviewed.
