title: The effect of a menhaden oil-containing diet on hemostatic and lipid parameters of nonhuman primates with atherosclerosis.
abstract: Three species of nonhuman primates were fed an atherogenic diet for 6 months (baseline period) and a menhaden oil (EPA)-containing diet for 8 weeks (test period) during which various hemostatic and lipid parameters were compared. The EPA-rich diet prolonged bleeding times, inhibited platelet aggregation response to ADP and collagen, and increased mean platelet lifespan. This diet elicited an increase in the polyunsaturated fatty acids C20:5 (EPA) and C22:6 (docosahexaenoic acid) at the expense of C18:2 (linoleic acid) and C20:4 (arachidonic acid) in pooled samples of platelet membranes, creating an increase in the ratio of n-3/n-6 polyunsaturated fatty acids. The serum lipid response to a menhaden oil diet comprised a nonsignificant decrease in total serum cholesterol and a significant decrease in HDL cholesterol.
