If you like sweet food, fried food, instant food, or often eat in restaurants, please pay attention! Today, let’s talk about the time bomb hidden in these foods – trans fatty acids. Generally, trans fatty acids come from the frequently used vegetable fat powder in the food industry. Do you want to know that the fat powder will be metabolized? You can get the answer you want from the relevant answers of trans fatty acids.
First of all, a few questions are raised
1. What are trans fatty acids?
2. Do hydrogenated oils in food processing contain trans fatty acids?
3. Are all trans fatty acids artificially synthesized?
4. How long does it take for trans fatty acids to metabolize in the body?
What are trans fatty acids? The fat produced by catalytic hydrogenation of oil is called trans fat (also known as hydrogenated vegetable oil).
Natural animal and vegetable oils generally contain a variety of unsaturated fatty acids, which are mostly liquid at room temperature, which is inconvenient for transportation and storage; at the same time, when these oils and fats interact with oxygen, light and microorganisms, they produce aldehydes and ketones, as well as various oxidation products and bad odor, which is easy to cause oil deterioration and seriously affect the quality of oil.
In order to overcome these shortcomings of unsaturated fatty acids in oils, hydrogenation technology of animal and vegetable oils was invented in the early 20th century, so as to improve the thermal stability and antioxidant stability of oils and extend the storage life of oils. At that time, it was thought that vegetable oil was healthier than animal oil, and replacing animal fat with cheap and “healthy” hydrogenated vegetable oil was considered an improvement at that time. However, future research found that in the process of hydrogenation, trans fat is more harmful than saturated fat. This is the original health for the sake of natural oils and fats, unexpected.
Are all trans fatty acids synthetic? There are two kinds of trans fatty acids, one is natural trans fatty acids, the other is non natural trans fatty acids.
Natural trans fatty acids: they are found in dairy products such as milk. This kind of trans fatty acid not only has no harm to the human body, but also can reduce the accumulation of fat in the body, which plays a role in the metabolism of lipid and glucose. Therefore, we should not only stay away from it, but also eat it safely.
Unnatural trans fatty acids: although they look like natural cream and can have the same effect as natural cream, making cakes more soft and elastic, and making fried chicken and French fries more crispy and delicious, these trans fatty acids are not good for human body and are the killers of human health.
How long does it take for trans fatty acids to metabolize in the body? Almost all trans fats in daily foods are manufactured artificially. Therefore, it is not easy for the human body to metabolize and excrete normally. This process takes 51 days.
Because they are not easy to digest, they are prone to obesity, and often eat foods containing trans fatty acids, which will increase the risk of coronary heart disease, cardiovascular and cerebrovascular diseases and Alzheimer’s disease. If women in pregnancy or lactation eat this kind of food, it will affect the growth and development of the fetus or infant, suffering from essential fatty acid deficiency, which is easy to affect the development of the central nervous system.
Generally speaking, the intake of trans fatty acids per person per day should not exceed 2G. Therefore, we only need to control diet, choose healthy and nutritious food, and provide time for trans fat to be discharged from the body in time, so that the health of the body is not easy to be affected, and the metabolism of fat powder will be more smooth.
