Dietary and adipose tissue content of linoleic acid in 40-year old men
1980
Walldius, G. | Callmer, E. | Olsson, A.G.
The fatty acid composition of the diets of 10 Edinburgh and 10 Stockholm men was analyzed in order to determine whether dietary fats explain the great difference in linoleic acid content of adipose tissue observed in these 2 groups. These subjects represent populations with either low (Edinburgh) or high (Stockholm) linoleic acid percentage content in their adipose tissue. The fatty acid composition of lipid extracts from replica diets ("reconstructed diets") based on weighted 7-day food records was determined. Foods and beverages were prepared as usual before chemical analysis. The low-group diets had a significantly lower relative linoleic acid content and higher myristic and palmitic acid percentage contents than the high-group diets. Dietary and adipose tissue linoleic acid intakes were the same in the 2 groups. These findings suggest that the quality, rather than the quantity, of dietary fat determines the relative content of linoleic acid in adipose tissue.
