The management measures of trans fatty acids in various countries can be roughly divided into the following three means:
One is through labeling management, such as mandatory or voluntary labeling, that is, labeling the content of trans fatty acids on food labels and making requirements on their claims. China belongs to this category. The United States stipulates that each food can be labeled as zero if it contains no more than 0.5g of trans fatty acids, while the European Union adopts voluntary labeling.
Second, dietary recommendations suggest that the intake of trans fatty acids should be as low as possible or not more than a certain level, such as the Netherlands. For example, Denmark stipulates that the trans fatty acids in all commercially available oils should not exceed 2G / 100g.
Is the intake of trans fatty acids in China more than that in western developed countries?
According to the “dietary intake level and risk assessment of trans fatty acids in Chinese residents” released by the national food safety risk assessment center, the average daily intake of trans fat in China is 0.39 g, equivalent to 0.16% of energy supply ratio, which is significantly lower than that of western developed countries and far lower than the recommended value of World Health Organization (who) (less than 1%).
Generally speaking, the overall health risk of trans fatty acids for Chinese residents is very low, but for about 0.42% of urban residents, the energy supply ratio of trans fat has exceeded 1%. Most of these people are students in school. The main reason is that they eat more fatty foods than ordinary people. It’s not just a trans fat problem. Too much energy, too much saturated fat intake should also be noted.
