In recent years, there is a popular saying that if you want tohave good skin, anti-sugar is indispensable. In the eyes of many beauty lovers, sugaris the "number one killer" of the skin. Eating sugar can easily cause spots and acne, and it will also make the skin slack, sagging and have wrinkles, so many people do not even eat staplefoods and fruits in order to prevent sugar intake. This is theso-called "anti-sugar diet."
As soon as the concept of "anti-glycation" was launched, there was a huge customer base, and there was a market where there was demand. Anti-sugar drugs, anti-sugar pills, anti-sugar oral liquid, anti-sugar facial cleansers, anti-sugar facial masks... a variety of anti-sugar products emerged one after another, although all of them are worth hundreds of thousands, they are still very popular. Today we are going to discuss, can the anti-sugar diet, which some people call "the strongest facial rejuvenation technique in the universe," really make us younger?
① Not all glycation reactions are harmful to the skin;
② Blindly "quit sugar", may hurt the body first without keeping the skin;
③ Most anti-sugar products on the market have not been professionally verified, and there is no scientific basis for anti-sugar products.
Saccharification reaction is good or bad
AGEs are the "skin killers"
According to experts, there are two types of glycation reactions: one is the beneficial enzymatic glycation reaction, which refers to the combination of sugar and protein under the action of enzymes to generate glycoproteins necessary for life activities. This type of glycoprotein has important immunity It can help the human body resist germs, as well as blood clotting and wound repair.
The other is a non-enzymatic glycation reaction, in which excess sugar is directly combined with protein without the action of enzymes to produce advanced glycation end products, referred to as AGEs. For example, the oily reddish brown on the surface of braised pork, the reddish brown on the surface of bread after high-temperature baking, etc., are all typical signs of AGEs.
According to Chen Wei, chief physician of the Clinical Nutrition Department of Peking Union Medical College Hospital, Academy of Chinese Medical Sciences, "glycation" and excessive "glycation" are not the same thing. It will still produce AGEs and happens on "saccharify" even if eating less sugar or do not eat main course. It is not advisable to quit sugar, as nutrition experts said. The key is to control it, one side is to control the intake of sugar; the other hand, we have to find appropriate cooking ways avoid food which contains AGEs.
Under high temperature conditions, Glycosylation final product which calls AGEs may be produced after boiling, frying, steaming, or stir-fryingv during cooking, as Chen Wei introduced. That is true way to reduce intake of AGEs is less eating snakes, desert, etc appropriately.
The most important thing is having good habits to get healthy skin.
