| Outline of Final Research Achievements |
We compared the fatty acid composition between Sri Lankan and Japanese patients with diabetes, dyslipidemia, or hypertension. We found that the mean concentration of circulating myristic acid (14:0) was much higher in Sri Lankan patients than that in Japanese patients. This finding might reflect on the fact that coconut oil is rich in myristic acid (14:0). Additionally, we found that the concentrations of circulating linoleic acid (18:2 n-6), α-linolenic acid (18:3 n-3), and eicosapentaenoic acid (20:5 n-3) were higher in Japanese patients than those in Sri Lankan patients. The major sources of these fatty acids were vegetable oils and fish, which are consumed more in Japan than in Sri Lanka. We also examined the association of circulating fatty acid composition with arterial stiffness in each country. The odd-chain saturated fatty acids (15:0+17:0) might be inversely associated with arteriosclerosis in Sri Lanka.
