On the positive side, everyone realized the importance of health and began to pursue a healthy life. Unfortunately, some people spread some wrong ways of keeping in good health under the banner of popular science, which has caused many misunderstandings to many people who are keen on keeping in good health. The more they keep in good health, the worse their health will be.
For example, is it good for your health to walk more and drink more water? The doctor reminds: You think you are keeping in good health, but you are actually losing your life.
As the saying goes, "Take a hundred steps after a meal, and you will live longer than 99". Many people regard this sentence as a wise saying. They walk for half an hour to an hour after meals every day, which is called health preservation. But after several years of persistence, they found that their knees began to ache, and some old people also had osteophytes and spurs.
Walking is really a good exercise, especially for the elderly, but I only know that walking too much will eventually hurt myself. Walking depends on the tibial joint and patella. The articular surface and capsule of the elderly have already shrunk and squeezed. If the friction is constantly increased, it will only increase the damage.
In addition, some people who seldom exercise at ordinary times are not suitable for taking 12 thousand steps suddenly. They should relax step by step, such as taking a walk every other day, taking 500 steps to rest, relaxing muscles and joints, and increasing calcium intake after each walk home. This is the correct health care.
The human body is 70%-80% water. People can go without food for a week, but they must not go without water for three days. This shows that water is very important to the human body, so someone put forward the concept of "eight glasses of water a day" a long time ago, saying that you have to drink water before you feel thirsty, so that you can be healthy.
In fact, the water required by the human body is about 2-3L per day, and not all the water is supplemented by drinking water. There is water in meals, soups and drinks, so drinking water should be analyzed in detail. If you have enough drinking water every day, it is enough to control the drinking water at around 1L (about two mineral waters). If the water intake is low, of course, it can be supplemented.
Excessive drinking water will lead to dangerous "water poisoning" and increase the burden on the kidneys, which may lead to acute renal failure. If there is too much water in the blood, there will be "hyponatremia", which will kill people in the most dangerous time.
Our nation pursues eating while it is hot, but it often turns into eating while it is hot. When I was a child, my family liked to prepare a cup of hot water every morning, and this glass of water has just boiled, and the temperature is 100 degrees, so my family would say "drink it while it is hot".
Anyway, eating while hot is definitely good for our health, but if the food is too hot, it will cause damage to our mouth, esophagus and gastric mucosa. In the long run, these delicate mucous membranes will begin to squamous metaplasia, and they will be oral cancer, esophageal cancer and gastric cancer if they are not careful.
In Guangdong, Sichuan and other places in China, people like spicy food very much. Cantonese people like to drink raw porridge and soup, while Sichuanese like spicy hot pot. These foods with temperatures exceeding 80 degrees will directly destroy the normal physiological structure, so people in these places generally suffer from more cancer.
Whole grains are recognized as nutritional conditioning products, and are the best partners for people who lose weight and have high uric acid to improve their symptoms. However, whole grains taste ordinary, and not everyone is used to eating whole grains. Therefore, in order to earn a gimmick, some merchants grind the grains into powder and sell them as rice noodles, and the signs they play are still healthy.
In fact, it is unhealthy for whole grains to be ground into powder. Dietary fiber is the most nutritious element in whole grains, which can not be digested and absorbed by people, but can promote gastrointestinal peristalsis. Once the whole grain is ground into powder, its dietary fiber will be destroyed, leaving only sugar.
Therefore, if you eat cereal flour regularly, you will not only be unable to keep healthy, but also lead to excessive sugar intake, which will increase your blood sugar and eventually lead to the onset of diabetes.
Vitamins play a very important role in maintaining human health, but under normal circumstances, the human body will not be short of vitamins, because the daily diet is rich in vitamins, but it happened that some people listened to rumors and bought vitamin tablets to supplement themselves, regardless of whether the body is short or not, but it is not good for the body.
Vitamin C can resist aging and promote metabolism, but if vitamin C is taken in too much, it will also cause irritation to the stomach and intestines, which will lead to urinary calculi and some will also lead to arteriosclerosis.
Others like to supplement calcium. Note that too much calcium intake will lead to hyperosteogeny and kidney calculi.
The correct way to supplement vitamins should be to eat more fruits and vegetables, which contain a lot of dietary fiber and essential vitamins. Have time to bask in the sun and improve the absorption and utilization of vitamins. Sunlight can synthesize vitamin D3, which can promote the absorption of calcium and protect the kidneys.
In short, some ways of keeping in good health are not desirable. All ways of keeping in good health should be analyzed in detail and the principle of moderation should be adopted, otherwise it will be harmful to the health.
