There are many theories about aging, among which saccharification is a relatively new one. What is saccharification?
Under normal circumstances, after food enters the human body, it will first be decomposed into small molecules by specific enzymes, then the small molecules will be absorbed by the human body, and finally react with enzymes to provide energy or become a part of the human body. Since there is a normal situation, there is naturally an abnormal situation. If blood sugar is at a high level for a long time, blood sugar can be combined with various protein, such as hemoglobin, retinal protein, etc., without the involvement of enzymes. This combination is called non-enzymatic saccharification (NEG) of sugar. The skin also has protein, such as elastin and collagen. Non-enzymatic saccharification of sugar and elastin can cause skin thinning; Non-enzymatic saccharification of collagen will cause structural changes of collagen and reduce skin elasticity.
Therefore, saccharification is indeed an accelerant of skin aging. However, as mentioned above, there are many theories of aging and many factors that affect skin aging. Judging from the existing data, the effect of saccharification on skin is far less than that of ultraviolet rays.
Step 2 quit sugar
Quit adding sugar, eat less fruits with high sweetness, eat less polished rice and white flour, and stick to a gluten-free diet. The former has some truth.
The World Health Organization suggests that both adults and children should pay attention to limiting free sugar. The so-called free sugar refers to the sugar in honey, syrup, fruit juice and concentrated fruit juice, as well as the extra sugar added in the process of producing food. They are all "naked" and are easily absorbed by the human body, which in turn leads to high blood sugar in the human body. High blood sugar level, on the one hand, will damage blood vessels, and vascular disease is the first cause of death in diabetic patients. On the other hand, as mentioned above, it can cause saccharification reaction and produce saccharified protein. The combination of sugar and protein is sequential. Generally speaking, hemoglobin is affected first, which is why diabetics should check the number of glycosylated hemoglobin. And then affect retinal proteins. If the blood sugar control of diabetic patients is not ideal, eye complications and even blindness may occur. In contrast, most of the sugars in fruits and vegetables are wrapped by cell walls, which has much less influence on blood sugar. White rice flour is similar to free sugar. Compared with coarse grains, it is easier to be absorbed and has a greater impact on blood sugar.
As for gluten-free, gluten is a kind of protein in wheat flour. In Europe and North Africa, about five thousandths of people suffer from gluten intolerance. The immune system of these patients will attack the enzymes involved in gluten metabolism, thus interfering with gluten digestion and absorption. For these people, gluten-free diet is necessary, but for us ordinary people, there is no evidence that gluten-free diet is healthier.
3. Super food
The concept of super food was first put forward by American doctors engaged in dietotherapy in 1980. It is defined as a natural food with superior nutrition, comprehensive nutrition, low calorie and good health. Such as blueberries, avocados and flaxseed. To be fair, these are all good foods. However, the human body needs all kinds of nutrients, and no food can fully meet the needs of the human body. Therefore, it is unnecessary to deliberately pursue a certain super food.
Let's talk about the endless stream of anti-saccharification products.
First of all, as mentioned above, saccharification has not become a research hotspot until recent years. The way and influencing factors of saccharification are still being explored. In the case of unclear principle, it is obviously unreliable to expect a product to completely solve the saccharification problem. Secondly, there is a general principle in health: unless you have certain diseases, you don't rely on various forms of supplements.
For example, when running, the human body will inhale a lot of oxygen. These oxygen will lead to oxidative stress, produce free radicals and damage normal human tissues. On the other hand, regular exercise can effectively mobilize the body's defense system and increase the body's ability to scavenge oxygen free radicals. Generally speaking, exercise is beneficial and can delay aging. Studies have shown that taking extra vitamins can interfere with the body's regulation process. ...
Various supplements, some useless, some inaccurate, and others, as mentioned above, interfere with the human body and have a counterproductive effect. Therefore, in the final analysis, the key is to maintain a healthy lifestyle.
