2. Improve low-density lipoprotein cholesterol and promote arteriosclerosis.
3. It affects the normal growth and development of infants and adolescents, and may have a negative impact on the development of the central nervous system.
4, leading to obesity. Hydrogenated oil can produce a large number of trans fatty acids. According to health experts, fat is metabolized in the body for 7 days, while trans fat can be metabolized in the body for 50 days, which is also the reason why foreign fast food can lead to obesity.
The basic principle of oil hydrogenation is to add metal catalysts (nickel series, copper-chromium series, etc.). ) and introduce hydrogen when heating vegetable oil containing a large amount of unsaturated fatty acids, so that the double bonds in unsaturated fatty acids combine with hydrogen atoms to form fatty acids with low unsaturation, resulting in an increase in the melting point (hardness) of the oil.
Because hydrogen is added in the above reaction to harden the oil, the oil obtained by this treatment is different from the original property and is called "hydrogenated oil" or "hardened oil", so its process is called "hydrogenation".
Extended data:
Like other things harmful to health, it is always discovered after a period of time. The harmfulness of hydrogenated oil reported by the media should arouse consumers' vigilance. However, influenced by the lifestyle of modern society, there is a gap between consumers and food processing and production, and they simply don't know or understand what harmful ingredients are contained in food. This depends on the food regulatory authorities, who will check for consumers and limit the content of harmful ingredients by setting strict food standards.
We have encountered many cases of food safety crisis, and our psychological endurance has been tempered to the world-class level. Hydrogenated oil is a hidden health bomb, its harmfulness is not obvious, and it even captures countless consumers because of its delicious taste. Therefore, in order to remove the harmfulness of hydrogenated oil, in addition to formulating content standards, various auxiliary measures should be taken, including popularizing health knowledge, advocating healthy eating habits, and supervising hydrogenated oil production enterprises throughout the process. This health project needs to be started as soon as possible, and it cannot be delayed for a few days, so as not to cause a greater health crisis.
