The metabolism of trans fatty acids is the same as the metabolism of common fatty acids, there are metabolic pathways such as synthesized fat and oxidized energy supply. 1. Synthetic fat: after being absorbed, trans fatty acids can react with triglycerides to synthesize triglycerides, i.e. fats, in the intestinal tract, liver cells and blood, which will increase the content of low-density lipoproteins in the blood and cause hyperlipidemia. In addition, it will accelerate the synthesis of cholesterol in the body, leading to atherosclerosis in the long term. 2. Oxidative energy supply: trans fatty acids can be activated by β-oxidation for energy supply. However, since this process will damage the cardiovascular system, it is not recommended to use trans fatty acids as energy-supplying substances. In addition to damaging the cardiovascular system, TFAs also accelerate the production of cholesterol in the body, and blood lipids rise rapidly, leading to vascular sclerosis. Long-term consumption of foods containing trans fatty acids can easily lead to hypertension, diabetes and other chronic diseases. It is recommended to eat a light diet, and when hyperlipidemia is detected, it is recommended to go to the hospital for timely lipid-lowering treatment under the guidance of a doctor.
