Introduction: Longevity is the hope that people have always dreamed of. After a long period of scientific research, scientists have proposed that limiting food intake from middle age can also extend human life.
The so-called food limitation refers to two things: first, not overeating, let alone bingeing; eating only seven to eight-tenths full per meal is sufficient. Second, it means reducing the intake of animal fats and sugar.
So, why can food restriction lead to longevity? This is mainly due to:
1. Food restriction can reduce the burden on the gastrointestinal tract. Overeating often加重 the burden on the gastrointestinal tract, leading to indigestion. This way, undigested food stays in the intestines for a long time, producing many toxins and carcinogens. These toxins and carcinogens not only easily cause gastrointestinal diseases, but also damage the central nervous system, causing aging.
2. Food restriction can prevent and delay the degeneration of brain function. Scientific research has shown that there is a substance in the human brain called "fibroblast growth factor". After a person overeats, the amount of this substance increases by tens of thousands of times compared to when they are on a restricted diet. This growth factor causes fat cells and capillary endothelial cells to enlarge, promotes arteriosclerosis, leads to insufficient oxygen supply to the cerebral cortex, and ultimately results in brain atrophy and brain function degeneration, thereby affecting a person's lifespan.
3. Food restriction can prevent premature aging. When people breathe, about 2% of the oxygen inhaled is catalyzed by oxidases to form active oxygen (free radicals). Active oxygen is extremely harmful to the human body. It can cause cell damage, hardening of arteries, and thus lead to diseases and promote aging. Scientific experiments have confirmed that the more energy the human body takes in, the more active oxygen is produced, and the faster the aging process. Therefore, it can be seen that food restriction can slow down aging and extend life.
4. Food restriction can reduce the incidence of "rich man's diseases". In recent years, due to the great improvement in living standards, more and more people are suffering from "rich man's diseases" such as hypertension, hyperlipidemia, coronary heart disease, cerebral thrombosis, diabetes, and gout, which have brought serious harm to people's health and lives. The occurrence of these diseases is closely related to excess nutrition in the body. Food restriction can control energy intake, avoid excess nutrition, and reduce the chance of "rich man's diseases".
