In the matter of getting fat, scientists have a new discovery
Author:Institute of Physics of the Ch Time:2022.08.31
Middle school textbooks tell us that when we eat high starch foods such as rice or noodles, those starch will be hydrolyzed by the human body into glucose, and then enter the blood, which increases blood sugar Glucose enters other tissue cells and is used and stored; in addition, sugar will be transformed into fat through multiple metabolic channels, so when the human body is too much sugar, obesity often follows.
But we need to know that the mechanism of obesity is far more complicated than brief descriptions in textbooks. Many slimming people pay close attention to the "carbon water" and "fat" in the nutritional composition table, and strictly control the "big cards" of daily intake and consumption. Of course, this precise self -discipline has certain truths and effects. Make obese problems.
Richard Johnson, a well -known medical professor and popular science writer in the United States, has long been committed to studying obesity roots, as well as diseases such as diabetes, hypertension, and chronic nephropathy. In his opinion, interpretation of obesity can not around the fruit sugar metabolism, "salt" and "moisture" should also be highly valued by thinkers.
In the following articles, he scored the theory of "fruit sugar to gain weight" and put forward a new strategy of weight loss.
Fructose does not affect appetite
Will encourage more to eat and promote weight gain
Fruit and honey contain a lot of fruit sugar. It is the same as glucose, but it cannot be directly used by the human body like glucose. Instead, it enters liver metabolism first, and then converts glucose, glycogen or fat -this unique absorption and use path can "unlimited" "Encourage" the biological body long.

As mentioned earlier, when we eat a bowl of rice, the level of insulin in the body will increase due to increased glucose content in the blood. It is responsible for sending blood sugar into cells for energy supply or reserves; at the same time, the body will secrete More leptin (leptin), thereby reducing appetite, accelerating energy consumption, and hindering fat storage.
But the metabolism of fructose is not directly under the jurisdiction of leptin. In other words, after intake of fructose, appetite will not decrease, energy consumption will not accelerate, and the body is still full of foraging power. On the other hand, the efficiency of fructose to fat is very high, and it may even induce insulin resistance, resulting in a reduction in the efficiency of glucose, further intensifying the tendency of longness.
The attributes of fructose encouraging long -sisters seem to be focused on chemical significance.
Before the farming era, ancient humans mainly relied on carbohydrates to live in their lives. They could be rich in starchy grains and rhizome foods. Fruits were the most easy -to -pick foods. Because fructose intake does not reduce appetite, ancient humans will continue to pick fruit and eat, and drive the maximum glycogen and fat storage under the sense of hunger, thereby increasing the possibility of survival.
This "fructose inlet chemistry" is now reflected in PSAMMMOMYS OBESUS.
Fatty sand mouse that is easy to get rich and wealthy
The fat sand mouse mainly lives in the desert and saltwater marsh in North Africa, and reluctantly rely on the stems of Salicornia. Salt grass is a plant -like plant. Although the nutrients are very low, it is rich in salt water that is comparable to seawater.
Both Asia and Africa have fat sand rats
Decades ago, scientists put fat sand mouse in the laboratory to raise 1/2 of the amount of carbohydrate required for ordinary rodents, and then supplemented with fresh vegetables. As a result, they quickly developed obesity and diabetes. When scientists only offer fresh vegetables, the fat sand mouse can maintain a slim figure.
By 2018, American scholars discovered that this kind of fertilizer sand mouse, who had only suffered a bitter life and was easy to get rich, and had metabolic problems. High -salt diets based on salt -horn grass would stimulate them to transform a small amount of carbo water intake into endogenous Sexual candy, which leads to leverin resistance and exacerbates obesity tendencies.
Facing the living environment of food scarce and fresh water scarce, this "high salt → fructose" metabolic mode activates the "survival switch" of animals, so that it can protect the desert, but it cannot live a wealthy day.
So, how will this high -salt intake affect human fructose metabolism? Is eating less salt and drinking more water is one of the standard answers to control weight?
Dehydration will promote fruit sugar production
Fructose and glucose are the same division of the same division, which can be transformed into each other. Of course, the human body also has the ability to make fructose. When the blood glucose level is high (for example, after eating a lot of potatoes or bread), the output of fructose will increase.
High -salt intake can cause dehydration of the body, and dehydration can significantly promote the transformation of "glucose → fructose", which leads to fat accumulation.
That's why, salt and pepper fries are particularly easy to gain weight. High -salt is simply a catalyst that promotes "starch → fructose".
Studies have shown that most overweight or obese people do not replenish enough water, easier to dehydrate than lean seeds, and also take more salt. In addition, they often have high -level vasopressin -a hormone that helps the kidneys to maintain water to regulate urine volume. (Water deficiency people need it particularly.)
Scientists have found that in addition to maintaining moisture, this kind of compressionin will also participate in fructose metabolism and indirectly stimulate fat production.
People mainly obtain fructose from the sugar and high -fruit candy corn syrup. Foods rich in high -fruit sugar corn syrup include jam, honey, juice drinks, refined bread and biscuits.
In view of the above, can we say, "Drinking plenty of water can help lose weight"?
Coupled colleagues in the medical community often scoff at such statements. However, scientists have discovered that more water is supplemented to experimental mice, which can indeed control its weight gain. The development of Prediabetes is delayed -even if their diet is rich in sugar and fat, the effect is still. Another evidence shows that most people have too little water drinking, and increasing water intake may indeed help obese people lose weight.
Of course, drinking 8 cups and drinking water is enough, drinking too much may happen. There have been cases of "water poisoning" caused by a lot of drinking water. For those patients with heart, kidney or liver disease, ultra -long runners, and those who have just undergone surgery, they need to be cautious when they increase drinking water. It is best to consult this issue in advance.
For the ancestors of fertilizers and modern people, the diet of high salt and less water is of great significance, but modern people no longer live a life of hunting collection, so we need to drink more water and eat less salt. The dietary habits that everyone can do provides us with affordable, simple and healthy strategies to prevent and treat obesity.
