We report fatty acid composition in perirenal and buttock adipose tissue in 714 deceased black and white men aged 25-44 yr in New Orleans. Percent saturated fatty acids were higher (p less than 0.001) whereas percent monounsaturated fatty acids were lower (p less than 0.001) in perirenal than in buttock fat. Percent linoleic acid was similar in both races. We conclude that dietary intake of linoleic acid is similar in both races. The trend of decreasing linoleic acid with advancing age suggests that either intake of linoleic acid progressively decreases or its mobilization rate increasingly exceeds deposition rate or both. Percent palmitoleic acid (16:1) is lower (p less than 0.001) and that of stearic acid (18:0) is higher (p less than 0.001) in blacks than in whites. We believe no explanation can rest solely on differences in habitual dietary fat intake.
