| Abstract：The effect of ruminant trans fatty acids (R-TFA) on human health is dose-dependent, which is harmful to human health if it exceeds a certain intake, and beneficial to human body if it is in a proper intake range. Therefore, the data of ruminant consumption was obtained by using the national nutrition and health survey in 1982, 1992, 2002, the statistical yearbook of nine provinces in 2012—2013 and the statistical yearbook of three provinces in 2012—2018. Then, the data of TFA content in ruminant product was analyzed, and the intake level of R-TFA in China was obtained. The results showed that the R-TFA intake of Chinese residents increased year by year from 1982 to 2012. In 2010—2012, the average R-TFA intake of Chinese residents was 0.076 g/d, and the average R-TFA intake in urban areas was higher than that in rural areas. From 2012 to 2013, the intake of R-TFA in China ranged from 0.055 g/d to 0.191 g/d, which was significantly lower than that in Denmark (0.8-3.4 g/d), and the highest level of R-TFA intake was in Xinjiang with 0.191 g/d. In addition, the intake of R-TFA in Liaoning, Shaanxi and Henan provinces had no significantly change from 2012 to 2018. This study not only revealed that the intake level of R-TFA in Chinese residents was far lower than that in western countries, but also found that the intake of R-TFA in China did not change much in recent years, and the relationship between the intake level of R-TFA and the health impact of Chinese residents needed to be further studied. |
