Trans fatty acids are more harmful to the human body than saturated fatty acids. They not only affect the human immune system, but also increase the harmful low-density lipoprotein cholesterol content and reduce the beneficial high-density lipoprotein cholesterol. Cholesterol content promotes arteriosclerosis and increases blood viscosity and cohesion. Experiments have shown that people who consume trans fatty acids accounting for 6% of calories have a significantly higher degree of whole blood aggregation than those who consume trans fatty acids accounting for 2% of calories. It can be seen that trans fatty acids can easily cause blood clots, leading to myocardial infarction and cerebral embolism. . Trans fatty acids can be directly transported to the fetus through the placenta. The mother's intake of margarine can cause the baby to passively absorb trans fatty acids through breastfeeding, thereby reducing male hormone secretion, affecting the growth and development of fetuses and infants, and affecting the central nervous system. It has adverse effects on the development of the brain, causing poor thinking and memory loss. Trans fat foods produce a lot of heat, and regular consumption can easily lead to obesity. Recently, a research team from Harvard University in the United States found that trans fatty acids are a risk factor for diabetes and are more harmful than saturated fatty acids. According to calculations, if trans fatty acids, which account for 2% of total food calories, are replaced with unsaturated fatty acids, the risk of diabetes can be reduced by 40%.

In view of the harm of trans fatty acids to human health, Denmark in Europe is the first country in the world to restrict the content of trans fatty acids in food.
