People often have many misunderstandings in the process of health care, some of which are related to factors such as misinformation, misleading public opinion and false advertisements. Therefore, we must avoid these misunderstandings, and at the same time correctly understand the dietary misunderstandings and health care precautions, so as to better carry out health care.

There are many misunderstandings about health care. Due to herd mentality, people in Russia and Japan often adhere to these wrong health care habits. Here I will explain some common health care misunderstandings in detail.

Myth 1: morning exercise

Many people think that the air in the morning is good and suitable for exercise. In fact, before the sun comes out, the carbon dioxide content in the air is high and the air quality is poor, so morning exercises should be arranged one hour after the sun comes out.

Moreover, it is not appropriate to do morning exercises on busy roads and dense forests, because a large amount of carbon dioxide is gathered, which is not good for your health. Secondly, foggy days are not suitable for morning exercises, because fog contains many harmful substances.

In addition, doing morning exercises on an empty stomach is easy to cause hypoglycemia. In the morning, coronary artery tension is high and sympathetic nerve excitability is high. The incidence of cardiovascular diseases is the highest from 6 am to 12 noon, so it is advisable to exercise in the afternoon or evening as much as possible.

Myth 2: Take a walk after dinner.

Many old people regard the old saying "Walk a hundred paces after a meal and live to ninety-nine" as a fitness motto. In fact, it is not scientific to walk after a meal.

From the point of view of modern medicine, when eating, especially when eating a full meal, the heart load of the elderly increases, and exercise after meals has obvious negative effects on the cardiovascular system. Therefore, the elderly should avoid exercising within two hours after a full meal.

Myth 3: Drinking mineral water is absolutely safe.

Many people say that mineral water is rich in minerals and is more beneficial to human body. However, mineral water may also be polluted by harmful substances (such as mercury and cadmium) in the land.

Recently, Dutch scientists analyzed 68 different brands of bottled mineral water produced in 16 countries, and found that mineral water is more susceptible to the pollution of dangerous microorganisms and bacteria, which contains more pathogenic microorganisms than expected.

Although these bacteria will not pose a great threat to people's health, for some people with weak immunity, bacteria in bottled mineral water are likely to pose considerable danger.

Myth 4: Dark eggs have higher nutritional value than light eggs.

Dark color is often synonymous with high health and nutritional value, but the color of eggshell is only related to the variety of hen. The nutritional value of eggs depends entirely on the health status of hens and the quality of daily feed.

Myth 5: Brown sugar is more beneficial than white sugar.

Brown sugar and white sugar are both extracted from sugar cane or sugar beet. The production process of brown sugar is slightly simpler than that of white sugar, which contains more glucose and cellulose, and releases energy faster and has higher absorption and utilization rate.

However, brown sugar contains almost the same sugar and calories as white sugar. Moreover, the taste of brown sugar is not as sweet as white sugar, so people will naturally put more when drinking tea and coffee, so in fact, brown sugar is sometimes more dangerous than white sugar.

Myth 6: The bath chart is very clean and difficult to wipe.

In fact, this will damage the stratum corneum of the skin. The stratum corneum and lipid membrane on the skin surface are isomorphic, forming a barrier protective layer of the skin, which can not only protect the body from external damage, but also prevent the loss of nutrients, especially water.

Rubbing hard with a bath towel will destroy this protective film. If you can hear the squeaking sound by rubbing your fingers on your skin after washing, it means you have washed too much. It is recommended to take a bath frequently instead of "taking a bath and rubbing hard". You can gently scrub it with a soft sponge dipped in shower gel, and only use a rubbing towel at the parts with thick cuticle such as elbows and knees.

Myth 7: Vitamin C can cure colds.

I don't know when vitamin C has become a common product for people to prevent and treat colds, and it is also a very popular "modern tonic", especially in winter, many people will supplement this kind of thing. People are convinced that vitamin C is a "cold buster".

But recent research by Australian and Finnish researchers shows that this statement has no scientific basis. Even taking 2 grams of vitamin C every day has no effect on treating colds.

Supplementing a small amount of vitamin C may shorten the time of catching a cold, but the effect is minimal and almost imperceptible. It is particularly noteworthy that the latest research found that people who are taking certain drugs to treat diseases, such as cancer patients who are receiving chemotherapy, will affect the treatment effect if they take vitamin C at the same time.

Misunderstanding of diet

1, only plants with stems have dietary fiber.

Food eaten in the body needs to be digested, and the speed of digestion has an impact on health. In life, we will find that some people digest quickly, while others digest slowly, which is often caused by different constitutions. Of course, the food itself also needs attention.

Foods rich in dietary fiber are generally easy to digest, such as celery. Celery contains a lot of dietary fiber, which makes the food with stems taste rough, and each plant cell contains cellulose and pectin, which belong to dietary fiber.

But it doesn't mean that plants with stems have dietary fiber. Our common sweet potato does not contain stems, but its dietary fiber is higher than celery. It can be seen that only plants with stems have dietary fiber, which is unscientific.

The more expensive the food, the better.

Food is not as expensive as possible. The energy provided by eggs is higher than that of abalone, and the content of protein is similar, and the content of fat and cholesterol is higher than that of abalone. The carbohydrate content of abalone is more than twice that of eggs, and the calcium, iron and selenium of abalone are much more than that of eggs.

However, there are more vitamins A, B 1 and B2 in eggs than in abalone, and the content of nicotinic acid is similar, but there is no vitamin C.

From the data point of view, there is little difference in nutritional components between abalone and eggs, but the content of individual nutritional components is different, but the price is very different. The price of an abalone can buy several kilos of eggs, so the more expensive food provides more nutrition.

Fresh vegetables are healthier than frozen vegetables.

If it refers to fresh vegetables just picked from vegetable fields, there is no problem with this statement. But in fact, most of our evening dishes are not so fresh, usually stored for a few days, and vitamins are gradually lost during storage.

On the contrary, vegetables frozen at ultra-low temperature can retain more vitamins, so quick freezing after picking can prevent the loss of vitamins.

4. Fruit is a perfect dietary substitute.

Fruit is a common food in life, with sweet taste and rich nutritional value, so nutritionists have always advised us to eat fruit often.

In addition, vitamins and dietary fiber contained in fruits can promote intestinal peristalsis, which is very helpful to lose weight. In addition, the calories of fruit are lower than other foods, so people always think that fruit is a perfect meal replacement food.

Searching for the keyword "fruit to lose weight" on the Internet will always bring out a lot of content about losing weight with fruit. One of them is to eat fruit without eating anything, even if you are hungry, and fill your hunger with fruit.

Fruit is really nutritious, and eating fruit regularly is also very helpful to lose weight, but it is actually not advisable to replace meals with fruit.

Nutritionists have always advised us to have a balanced diet. The human body needs to supplement a lot of nutrients every day, most of which need to be taken from food.

Although fruits are rich in nutrition, they cannot provide essential fat, protein and carbohydrates. Once the human body lacks these nutrients, over time, the human body's resistance will deteriorate, and diseases will also take the opportunity to damage human health.

Salad is extremely beneficial to human health.

Probably because of the low calorie, salads are favored by many people. Salad contains as much as 80% water, but in fact, the nutrients that the human body takes from salad are also very low.

Not only that, most women should not eat too much salad. Because women's physique is usually cold, eating too much salad can easily lead to poor metabolism, poor blood circulation, bad menstruation, dull skin and even wrinkles.

In addition, the nitrate content of many vegetables is also high, mainly from the fertilizer for growing vegetables, and its potential harm should not be underestimated.

6. Eating assorted cereals for breakfast is more resistant to hunger than bread.

Assorted cereal contains diced fruit, walnuts, raisins and other foods, and milk is added, which seems to be more abundant, but in fact it contains about the same calories as bread slices with jam.

But people who eat assorted cereals usually have low blood sugar content, and the higher the sugar content, the less likely it is to make people feel hungry. Therefore, in fact, eating bread and jam is more resistant to hunger.

7. Fruits that are not sprayed with pesticides need not be washed.

Even green fruits should be carefully washed with water before eating. Eggs on the peel of fruits (such as strawberries and apples) are invisible. If fruit is eaten without washing, it is easy to be infected by bacteria.

Matters needing attention in health preservation

First, have a good sleep.

It is best to fall asleep before ten o'clock every night. If you fall asleep before noon, according to the viewpoint of meridian injection, qi will flow to Yin Hui point, and at this time, a yang will be born. If you don't fall asleep before this time, not only the yang of the whole body will be damaged, but also the kidney yang will be deficient. When you sleep well, kidney yang will gradually flourish.

Second, we should persist in physical exercise.

Exercise can stimulate the yang of the human body. The best sports are swimming and hiking. I especially like hiking. My friends and I walked 10,000 meters a day, joking while walking. We were happy and not tired. The key is to get enough exercise.

Third, relax.

The main way is to practice Tai Ji Chuan or sit still. As long as you practice these things often, your outlook on life will gradually change.

Fourth, some specific exercise methods.

(1) Abdominal rubbing is a hard massage around the navel. First, the left hand turns 36 times clockwise, and then the right hand turns 36 times counterclockwise. This method can supplement the five internal organs and help the water valley transport.

(2) Then there is the method. The so-called "99 is in hand, the true grandson will not go", and the specific measures are available online. You can search and see.

(3) Lifting the ear over the head: the left hand lifts the tip of the right ear over the head for 36 times, one lifting and one releasing; Then raise your right hand over your head and lift the tip of your left ear 36 times.

(4) Point Changqiang Point, Zusanli Point and Xiangu Point (because there is an elixir method in front, there is no need to massage Qihai and Guanyuan Points).

(5) Beat the inner thigh with a horse stance.

(6) Standing on the pile, you can slowly shake your body left and right, and you can also move your crotch back and forth, so that Gong Zhuang can move and move at the same time, and the qi and blood can run well, which is more likely to produce a sense of qi.

Five, food supplement methods

Eat coarse grains, seafood and foods rich in zinc and Ve, such as leek, seahorse, sea cucumber, shrimp, loach, laver, yam, acanthopanax senticosus, beans, nuts, mutton and sparrows.

Six, medicine supplement

Just eat more Lycium barbarum and so on, and ginseng and astragalus can also do it. It is best not to use Morinda officinalis, Epimedium, Cynomorium songaricum, actinolite and all kinds of whips indiscriminately.

Seven, physical examination

Regular physical examination is also important. Whether there is a problem with renal function actually reflects the health of the body. Regular physical examination can give you the most complete understanding of your health.

Conclusion: The above are some health-keeping misunderstandings I have sorted out, as well as diet misunderstandings and health-keeping precautions. Everyone must know about it and correct their wrong habits in time in life. Only in this way can we exercise in a scientific and reasonable way. Finally, I wish you good health and stay away from illness.
