If a person has a good appetite and can pay attention to dieting, it is really good for health. Health experts have always advocated dieting to keep fit.
What effect does diet have on human body? To sum up, there are two points: first, it is conducive to the normal play of gastrointestinal function; Second, it can prevent and treat some chronic diseases. Chinese medicine believes that people's gastrointestinal function is "smooth and smooth." It shows that the gastrointestinal function is normal and unobstructed downward; On the contrary, it is pathological, such as vomiting and constipation. Therefore, Chinese medicine has the saying that "six fu organs" are supplemented by communication. Gastrointestine is an important organ in the six fu organs. Dieting can effectively keep unobstructed, so that every time food is ingested, it can be fully stirred, digested and absorbed in the stomach.
The basal metabolic rate of the elderly gradually decreases with the increase of age. At the same time, after entering old age, physical activity is reduced, and the heat energy consumed is also reduced accordingly. Therefore, the heat supply for the elderly should also be reduced accordingly. If people eat less when they are old, so that they eat too much, it will have a negative impact on their health. Because every meal is too full, blood will be concentrated in the gastrointestinal tract, which will inevitably lead to ischemia and hypoxia of important organs such as the heart and brain, and it is easy to induce or aggravate coronary heart disease, angina pectoris, myocardial infarction, cerebrovascular disease, diabetes, cholecystitis and so on. In addition, overeating can lead to obesity, which can cause many diseases. Research data show that compared with normal people, more overeating and obese patients die of tumors in middle age. Many foreign research data show that the vast majority of long-lived elderly people are normal or underweight.
World longevity researchers believe that dieting to slow down physical aging is a good way to maintain a long and healthy life. China ancient health experts also advocated that the elderly should "eat less". "Lao Lao Heng Yan" pointed out: "Eating less is always beneficial, and the spleen is easy to grind and transport, which is to melt semen. Otherwise, it is very easy to eat too much, which leads to injury, so eat less and tonify the spleen. " "Shou Shi Bao Yuan" is more clearly summarized as: "Food is half full and tasteless, and wine is only three times."
