Fatty acid compositions of serum lipids from elderly people (65 to 79 years old) in Koganei City of Tokyo were determined, and their correlation with dietary food intakes were examined. Cholesterol esters, triglycerides and lecithin revealed characteristic fatty acid profiles, respectively. Lecithin contained large amounts of eicosapentanoic and docosahexanoic acids (EPA and DHA) which belong to n-3 fatty acids as compared to other lipids. Sex differences in the fatty acid composition were found only in lecithin among serum lipids. Percentages of n-3 fatty acids were higher in males than in females, and were found to be positively correlated with the intake of fish. On the other hand, linoleic acid and n-6 fatty acids were shown to have positive correlations with beans. Arachidonic acid among n-6 had weak but significant correlations with eggs and milk.
