Article: Total fat and (n-3):(n-6) fat ratios influence eicosanoid production in mice

ABSTRACT Previous studies have not addressed the effect of differing fat intake on the effectiveness of varying (n-3) polyunsaturated fatty acid (PUFA) ingestion in altering tissue composition and eicosanoid production. This study examined (n-3):(n-6) PUFA ratios of 0, 0.11, 0.21, 0.41, and 1:1 with total fat at 5, 10, 15, and 20 g/100 g of diet and (n-6) PUFA fixed at 1.5 g/100 g of diet on tissue composition and peritoneal cell eicosanoid response to an in vivo inflammatory stimulus in 240 mice. Both (n-3) PUFA and total fat intake influenced tissue composition and eicosanoid biosynthesis. Increased (n-3) PUFA intake was associated with an increase in tissue (n-3) PUFA and a decrease in ...
