When we are eating biscuits, bread and cake, we have to face the temptation of cream. Do you know that these creams are made manually, which is called "margarine", also known as vegetable cream. Vegetable cream is processed from vegetable oil such as soybean and water, salt and milk powder. As a pre whipped product, vegetable butter can be used in birthday cake, bread sandwich, mousse cake and other foods. At present, it has been widely used in the field of baking.
With the popularity of vegetable cream in the food industry, its side effects are gradually emerging. It can increase the content of "bad" cholesterol (low density lipoprotein) in blood and reduce the content of "good" cholesterol, that is, high density lipoprotein (HDL). Therefore, it can increase the probability of heart disease, diabetes and other diseases.
The reason is that the hydrogenation reaction cannot be carried out completely. All fatty acids in fully hydrogenated vegetable oil have become saturated fatty acids. The melting point and hardness are too high to use, so it can only be partially hydrogenated.
But that's the problem. In hydrogenation, some double bonds have been opened and are about to bind hydrogen atoms, but they are not allowed to bind hydrogen atoms. In this process, the positions of the hydrocarbon chains above and below some double bonds are reversed to form trans fatty acids. Trans fatty acids contained in vegetable butter are substances harmful to human health.
Hazards of trans fatty acids:
1. Reverse test fatty acids can affect human memory, because trans fatty acids can resist a kind of cholesterol that can promote human memory;
2. Trans fatty acids almost do not exist in the human body, and are very difficult to be digested and absorbed by the human body, and are easy to accumulate in abdominal therapy, leading to obesity;
3. Trans fatty acids can reduce the secretion of male hormones and have a negative impact on sperm activity, resulting in the interruption of sperm physiological activity in the human body;
4. Trans fatty acids hinder the absorption of fatty acids in children who are in the period of growth and development, and also cause poor growth and development of the central nervous system. Therefore, margarine food is not a high-quality food, and it is best to have less contact with this kind of food. Even if you want to eat, you should eat it without affecting your health.
