Fatty acids of plasma total lipids, abdominal subcutaneous adipose tissue and omental adipose tissue were analyzed in 27 subjects including IGT and mild NIDDM patients who received surgical treatment of cholecystolithiasis. Their dietary habits were estimated by a combined recall and interview method. The subjects were divided into meat-eating group, fish-eating group and intermediate group. Meat group was shown to have consumed an increased amount of oleic acid (C 18:1) when compared with fish group. The latter group was rather characterized by the increased intake of long-chain polyunsaturated fatty acids such as C 20:5 and C 22:6. These long-chain polyunsaturated fatty acids were found to be significantly increased in fish group as compared with meat group. The fish intake accelerated the distribution of C 20:5 and C 22:6 more strongly in plasma than in adipose tissues.
Interestingly, C 18:1 showed rather constant body distributions among the 3 groups despite the marked difference in the rate of its intake, and C 18:1 was rather poor in plasma and rich in depot fat tissues in all groups.
