Professor Clade McKay of Cornell University in the United States made a food restriction experiment with mice, and compared the life span of free-eating mice with that of restricted-eating mice. The growth of diet-restricted rats was delayed due to the restriction of calorie intake, but their life span was prolonged by 40% ~ 100%. Other scientists reduced the food they fed to monkeys by 30%, and as a result, the life span of monkeys was extended by 1 time.
Why can food restriction prolong life? First of all, food restriction slows down the speed of metabolism and keeps the main organs such as heart, brain, lung, liver and kidney relatively young. Because food has a special heat-producing function, reducing diet will slow down the metabolic process. Japanese professors pointed out that after overeating, the growth factor of fibroblasts in the brain soared tens of thousands of times than before eating.
This substance can make capillary endothelium and fat cells proliferate, promote cerebral arteriosclerosis, make the brain premature aging, and other organs also have chain reactions; Food restriction slows down the decline of immune function, thus reducing the incidence of cardiovascular and cerebrovascular diseases, hyperlipidemia, nephropathy and tumors; Food restriction also has anti-free radical effect and delays cell aging.
The correct way is to eat seven or eight points full, eat less and eat more meals; Don't eat or drink. Always be hungry, stick to it, and you will live a long and healthy life. And if you want to live a long life, you should pay attention to other aspects besides food. We must ensure a healthy mind. A good attitude is very important for the health of the elderly. Only when we are in a good mood can we face everything positively, which will also keep us healthy better.
