First, many people think that eating bananas can relax the bowels. But in bananas, the cellulose content is not very high. Moreover, immature bananas are not delicious and sour, and the tannic acid contained in them has a strong astringent effect, which not only has no effect on constipation, but also aggravates constipation.
The second is to drink bone soup to supplement calcium. I think bone soup is very nutritious. I think all the calcium in the bone is in it, but it's not like this. Bone soup is low in calcium and rich in fat. Drinking it will not only increase blood lipids, but also increase uric acid and induce gout.
Third, many female friends think that eating pig's trotters can beautify the face. Everyone thinks that this trotter contains a lot of collagen, so eating more trotters can supplement our collagen and make our skin better. Actually, it's not. The collagen we eat in our stomachs has been digested and cannot be absorbed by the skin on our faces, so this method is also wrong.
Fourth, the diet is light. Is a vegetarian, don't eat meat, many friends with high blood pressure and hyperlipidemia, doctors will recommend a light diet, so many middle-aged and old friends are vegetarian and don't eat meat, thinking that this is a light diet. In fact, a light diet means not to eat more foods high in oil, salt and sugar. Meat dishes are an important source of high-quality protein, such as fish, shrimp, eggs and ribs. And middle-aged and elderly people can't be partial eclipse.
Fifth, many old people and even many young people are doing it, that is, they run away every day. They think that walking more than 10000 steps a day, 20000 steps or even 30000 steps is good for health. Actually, it is not. Under normal circumstances, we can walk about 6000 steps every day. Too much walking or even climbing mountains every day is very harmful to our knees. Therefore, we must pay attention to the above points.
