“…The primary data source for trans fatty acid values for the remaining 526 foods was direct chemical analysis. 17 – 19 , 21 – 33 For this, we searched the Pubmed, CiNii, and Medical Online Library databases for the English and Japanese literature reporting analyses conducted in Japan of the trans fatty acid content of foods. For the present study, we limited data to reports appearing after the year 1992 (ie, data reported during the decade preceding collection of the present diet records) in order to minimize the possibility of changes in the nutrient composition of food products.…”

“…Trans fatty acid values in the analytic data 17 – 19 , 21 – 33 were converted to grams per 100 g of food, adjusting for total fat content in the STFCJ 20 using the following equation: Trans fatty acid (g)/100 g of food = [ trans fatty acid (g)/total fat (g) in reference] × [total fat (g)/100 g of food in the STFCJ]. For any reference that reported the trans fatty acid value for a specific food as % fat without indicating the fat content (g/100 g) of the food, we used the fat content (g/100 g) provided in the STFCJ 20 to calculate the trans fatty acid value of the food.…”

“…However, few data are available on individual mean intakes estimated using trans fatty acid food composition tables covering foods high in trans fatty acids 1 , 12 , 13 in Asian countries, including Japan. Several estimates for Japanese populations have been reported, 14 – 19 but their usefulness is limited by problems with databases, 14 – 18 dietary assessment methodologies, 15 – 18 or sample sizes. 15 , 19 Thus, our aim in this study was to develop a comprehensive trans fatty acid database that encompasses broader categories of foods, and then to estimate trans fatty acid intake among a Japanese population by using 16-day diet records (DR).…”

BackgroundThe Standard Tables of Food Composition in Japan do not include information on trans fatty acids. Previous studies estimating trans fatty acid intake among Japanese have limitations regarding the databases utilized and diet assessment methodologies. We developed a comprehensive database of trans fatty acid food composition, and used this database to estimate intake among a Japanese population.MethodsThe database was developed using analytic values from the literature and nutrient analysis software encompassing foods in the US, as well as values estimated from recipes or nutrient compositions. We collected 16-day diet records from 225 adults aged 30 to 69 years living in 4 areas of Japan. Trans fatty acid intake was estimated based on the database and the 16-day diet records.ResultsMean total fat and trans fatty acid intake was 56.9 g/day (27.7% total energy) and 1.7 g/day (0.8% total energy), respectively, for women and 66.8 g/day (25.5% total energy) and 1.7 g/day (0.7% total energy) for men. Trans fatty acid intake accounted for greater than 1% of total energy intake, which is the maximum recommended according to the World Health Organization, in 24.4% of women and 5.7% of men, and was particularly high among women living in urban areas and those aged 30–49 years. The largest contributors to trans fatty acid intake were confectionaries in women and fats and oils in men.ConclusionsAlthough mean trans fatty acid intake was below the maximum recommended intake of the World Health Organization, intake among subgroups was of concern. Further public health efforts to reduce trans fatty acid intake should be encouraged.

“…“The FAO/WHO joint meeting of fat and fatty acid in human nutrition,” held in Japan in 2008, set out the target to intake of TFA less than 1% of total energy intake [33]. Kawabata et al pointed out that daily TFA intake could become higher than the predicted value if processed foods containing high levels of TFA were consumed, while the average intake of TFA in young women was lower than the WHO-recommended energy ratio (<1%) [34]. It is advisable to avoid especially high levels of TFA-containing foods during pregnancy and lactation.…”

To investigate the effects of a dam's dietary elaidic acid (EA) intake during pregnancy and lactation on the fatty acid composition of plasma, erythrocyte membrane, and brain in rat pups, we fed two groups of dams either a soybean oil diet (SOD) or a shortening diet (SHD) containing soybean oil (10%) or shortening (10%), respectively. Although EA was not detected in the SOD, EA accounted for 25.3% of all fatty acid content in the SHD. On day 8 after birth, the EA levels in the stomach, plasma, and erythrocyte membrane of pups nursed by the dams fed the SHD were 11.6 ± 1.03%, 7.18 ± 1.20%, and 5.82 ± 1.00%, respectively. Although on day 8 after birth the EA level of the brains of pups nursed by SHD-fed dams was 0.56 ± 0.24%, EA was not detected on day 21 or day 82 after birth. These results suggest that EA intake during pregnancy and lactation supplies EA to plasma, remains in the erythrocyte membrane of pups, and moves into the brain in early infancy.

“…In a separate study, we measured the intake of TFA in 25 young Japanese women, and found that subjects with a high dietary intake of processed foods rich in TFA may exceed predicted levels (27). When assessing TFA intake, therefore, it is necessary to pay attention to subjects who are consuming TFA more than on the average.…”

SummaryBecause trans fatty acids (TFAs) are a potent risk factor for coronary heart disease, it is important to know the amount of TFA consumed. We estimated TFA intakes of Japanese university students by direct measurement. Subjects included 118 students (57 males and 61 females) in two regions of Japan: Kanto (Tokyo area) and Okinawa. A dietary survey was conducted over six consecutive days using dietary records and photographic records. A single-day meal in the survey period was reproduced to measure TFA content by gas chromatography. The median values of TFA intakes (and energy percentage) estimated by the contents of reproduced meals for men were 0.43 g/d (0.22%) in Kanto and 0.30 g/d (0.14%) in Okinawa. Corresponding values for women were 0.49 g/d (0.29%) and 0.73 g/d (0.35%), respectively. Compared to the group with a low TFA intake, the subjects with a high TFA intake consumed significantly more energy from total fat and saturated fatty acids, and had a high ratio of TFA/linoleic acid. In addition, multiple regression analysis showed the intakes of TFA were positively associated with those of saturated fatty acids and groups of nonessential groceries such as cookies, cakes and pastries. In conclusion, the TFA intakes of these survey subjects were relatively lower than the WHO recommended energy ratio ( Ͻ 1%). However, nutritional education on dietary habits seems indispensable for those subjects who are consuming high volumes of TFA.
