The purpose of this study was to develop a food composition table for estimating the intake of trans fatty acids. We further examined whether the intake of trans-fatty acid estimated by this food composition table was reasonable for middle-aged and elderly men and women with borderline diabetes. We used 23 literature sources to calculate the average content of trans fatty acids per 100 g of 280 foods. For foods not reported in the literature, the trans fatty acid contents were replaced with those for similar foods. Finally, we calculated the average content of trans fatty acids per 100 g of food for 592 food items. We then calculated the average intake of trans fatty acids for 35 men and women with borderline diabetes using a 7-day continuous dietary record. The trans-fatty acids in 4,535 (99.9％) of the total 4,539 foods containing 1 g or more of fat per 100 g of the edible portion were calculated. The average intake of trans fatty acids was 0.66 g (％energy: 0.33％). Although it is necessary to consider the accuracy of this food composition table due to several limitations, our findings suggest that the food composition table for trans fatty acids we have developed may be reasonable for use in a nutritional survey for other groups in the Japanese population.
