Eating less is good for health.
For decades, researchers have known that mice whose diet is one-third lower than that of normal mice will live 40% longer, and this conclusion can also be applied to other mammals. The population of beermann Village in South America is less than 1000, but as many as 9 people are over 100 years old. They have a light diet, eating 1200 calories a day, and eating no meat or eggs. Their diet is mainly cereals and fruits, such as wheat, corn, potatoes, autumn bananas and grapes.
Indeed, people who eat less live longer. The less you eat, the longer you live. A study shows that mice in the laboratory eat less calories and live longer, even if they eat less calories when they are old. Studies have shown that reducing the calorie intake of mice can get immediate and good results, which can not only prolong the life span of mice by six months, but also reduce their cancer rate. The research report published in the Proceedings of the National Academy of Sciences also shows that even if you have cancer, reducing calorie intake can slow down the growth of tumors. For example, as a result of reducing calorie intake, the tumor mortality rate of mice dropped from 80% to 67%. Sibindeler, a scientist at the University of California, Los Angeles, said that reducing the calorie intake of elderly mice has the same effect on liver genes as dieting has on small mice. After years of research, some scientists have found that one of the secrets of prolonging life span is that people only eat a diet rich in vitamins and minerals and low in calories, that is, the diet remains moderately low in nutrition (but not malnutrition). This method has been proved to be very successful in the laboratory. Mice tested in this way only live for about two years, but now they can live for more than four years and still maintain the behavior and appearance of young people. Although it is not known how dieting can make animals live longer, studies have found that there are fewer gene mutations in mitochondria and fewer cell deaths in some tissues. Therefore, scientists believe that this may be one of the main mechanisms of dieting to delay aging. There are often several reasons for making up your mind to control your mouth and eating too much. First, some people with good living conditions don't know how to cherish happiness, don't consider nutrition, and only care about their hobbies. When they see food, they can't help it. The second kind is people who want to get enough nutrition and eat reluctantly. Some people need more calories physically because of intense activities. But it is foolish to eat for nutrition. Excess nutrition must not be absorbed by the body, but will become a factor of liver and kidney poisoning. People who eat too much often have hepatomegaly, because they eat too much food incongruously, and the gastrointestinal tract needs to digest it and borrow it from the liver. The more excretion, the heavier the burden on the liver. And the kidneys are in an unhealthy state because they eat too much and are too good. Many diseases are caused by not being able to control your mouth. In his book Eat Fast, Row Fast and Sleep Fast, Dr. Yokoo of Japan read the following passage: "Diabetes is caused by years of overeating and drinking delicious food, which leads to the failure of endocrine organs in the pancreas. Therefore, the prevention method of diabetes is not to eat meat and delicious food, and usually don't overeat or overeat. After a full meal, the gastrointestinal tract is over-expanded, which leads to the compression of the aorta passing through its back, the obstruction of blood circulation and the increase of blood pressure. Hypertension is the direct cause of cerebral hemorrhage. The cause of many incurable diseases also lies in improper diet. Overeating caused by indulgence of appetite, coupled with the lack of correct treatment, will become a refractory disease. And those who are willing to live to the age of 80 or 90 without pain, even if they don't practice any kind of health preservation methods, as long as they are willing to maintain a small amount of diet. There are many people who live so long. Many people have had this experience. When their mental state improves and they eat too much, they always feel sleepy. If you diet properly, once the physique of people who eat less changes, the sleep time is likely to be shortened. People who used to sleep eight hours a day now only need to sleep five or six hours. In fact, if you are really healthy, it is not unusual to have a stomach for a day or two. People who feel collapsed without eating a meal or two are likely to be signs of diseases such as gastroptosis or potential diabetes. A truly healthy person, if he doesn't eat a meal or two, will never feel weak, or feel dizzy and cold. " The less you eat, the healthier you are. The healthier you are, the lighter you are. The lighter the body, the fresher the body and mind, the brighter the body and mind, the more enlightened the wisdom, and the more dexterous it is. This is the experience of some vegetarians. Some practitioners say that when they are hungry at first, they will feel extremely weak, or have dizziness, palpitations, headaches and other symptoms, but after this time, their bodies will suddenly become refreshed, even though they are still full of energy when they are on an empty stomach, and their work is full of vitality. Even if the work is a little too hard, I won't feel tired. Once you get into the habit of eating less, your sleep time will be shortened, your body and mind will feel happy, you will not be tired easily, your mind will be clear, and your physical labor will be twice as much as others. The more you eat, the heavier your body, the lazier you are, and the dimmer your mood. Without wisdom, talent is clumsy. And some people of insight, although rich in status, not only pursue the desire of writing, but also live a life of food and clothing and enjoy life. The two longevity theories are interrelated, and besides genetic factors, behavior patterns are also extremely important. There are two theories that have been concerned for a long time. One is that eating seven or eight full points will lead to longevity, and the other is that hypothermia will lead to longevity. The former theory has been confirmed by many research results, and the second theory has also been verified, and there is a close relationship between them. The average temperature of normal people is 37 degrees Celsius, but a recent study found that 36.5 degrees Celsius may be better in terms of life span. If the normal body temperature of mice is reduced by 0.5 degrees Celsius, their life span can be increased by up to 20%, which is equivalent to an increase of 7 to 8 years. This result shows that lower blood temperature may prolong life. On the other hand, the body temperature of mice or mammals with less than one third of calories in their diet will drop by 0.5 degrees Celsius or more. Does hypothermia help delay aging, or does a low-calorie diet lead to hypothermia? In order to find out the mystery, the researchers used genetic engineering to lower the body temperature of mice. They implanted a gene into the hypothalamus of the mouse brain and a group of brain cells near this area to sense and control the body temperature, so that the brain mistakenly thought that the body temperature was high and issued a cooling instruction to cool the mouse body by 0.3~0.5 degrees Celsius. After cooling, the life span of female rats was prolonged by 20%, and that of male rats was prolonged by 12%. This study proves that the anti-aging effect of dietary restriction is related to hypothermia. The principle may be that low temperature delays metabolism and the production of other by-products, such as free radicals. And free radicals are the culprit that damages cells and promotes cell aging. As a result, the life span of cells is also prolonged, thus prolonging the life span.
