Erythrocyte linoleic acid, but not oleic acid, is associated with improvements in body composition in men and women.

ABSTRACT:

Scope

Supplementation with linoleic acid (LA; 18:2Ω6)-rich oils increases lean mass and decreases trunk adipose mass in people. Erythrocyte fatty acids reflect the dietary pattern of fatty acid intake and endogenous metabolism of fatty acids. The aim of this study is to determine the relationship of erythrocyte LA, with aspects of body composition, insulin resistance, and inflammation. Additionally, we tested for relationships of oleic acid (OA) and the sum of long chain omega-three fatty acids (LC-Ω3-SUM), on the same outcomes.

Methods and results

Men and women (N = 139) were evaluated for body composition, insulin resistance, and serum inflammatory markers, IL-6, and c-reactive protein (CRP) and erythrocyte fatty acid composition after an overnight fast. LA was positively
