1. A light diet is harmful to many elderly people. The most important thing for longevity is to be light in body and to supplement nutrition reasonably. The so-called lightness emphasizes less oil, less sugar, less salt and less spicy, rather than no seasoning at all. Many people think the original flavor is light, so they don't use any seasonings in the cooking process. But sugar can also provide energy for the human body. Commonly used salt contains sodium ion, which is also a nutrient needed by human body. If it is too light for a long time, it is unhealthy without seasoning. Only by following the correct principles can we achieve the goal of keeping healthy.
2. The food should be decomposed to facilitate digestion and absorption. The food should be warm, and it is best not to eat it while it is hot. Chew slowly, reduce the burden on the stomach and promote digestion. Old people must limit their meat intake. Some protein sources should be replaced by beans and bean products. Have some rice. In order to get enough calories and nutrition for the elderly every day, nutritionists suggest that the elderly eat five to six meals a day. Add vegetables and cook together. Fried food can cause a high fever. Eating old people often will lead to excess calories in the body, leading to obesity, which is not good for the body. In particular, eating fried food often increases the risk of cancer, because the oil used many times contains more carcinogens.
3. Old people's teeth often loose or fall off, and their stomach's digestive ability is not as good as before. They should eat soft food, not hard food, but hard fruit food. Of course, don't eat fried, greasy and indigestible food. Protein should be supplemented every day, because it is the necessary nutrition to make muscles stronger. When people get old, their muscles will shrink. If you don't strengthen muscle nutrition and exercise, it's easy to fall and hurt when you walk. Therefore, it is best to drink a glass of milk and eat an egg every day. The diet is hot, and the elderly have poor cold tolerance. If you eat cold food, it will cause the blood vessels in the stomach wall to contract, reduce the blood supply, and reflexively reduce the blood circulation of other internal organs, which is not conducive to health.
