With the development of economy, people's consumption level is getting higher and higher, their material life is getting richer and richer, and the demand for medical care is paying more and more attention. Especially their parents after 50/60/70 are the main force in the health care army. I am convinced that various "family" WeChat groups such as "Happy Family" and "Love Home" share various health articles every day.

The five most popular sentences in these essays, such as drinking 8 glasses of water every day, chicken essence is healthier than monosodium glutamate, not eating overnight dishes, eating trotters for beauty and so on. Are these so-called "health sayings" really credible? Is there a scientific basis? Are you really not lying?

Let me briefly explain my point of view:

This is the most absurd statement, saying that frequent eating overnight dishes will cause ai, because overnight dishes will produce nitrite, which is the ai component. This statement is actually correct. Overnight dishes do produce nitrite, not only overnight dishes, but also leftovers. In addition, meat dishes generally produce more nitrite than vegetarian dishes.

So according to this statement, you can't eat leftovers instead of overnight dishes. In fact, the amount produced is very small, completely within the food safety standards, so don't worry too much, but for the sake of good health and delicious food, try not to waste leftovers.

Every time I go shopping, I will pass by the shop that bakes pig's trotters on the street. There are always several beautiful young ladies waiting in line to buy pig's trotters. I've always wondered why young ladies are so keen on greasy trotters, because they all want to have a good figure. Later, I learned that they really thought "trotters can be beautiful".

Their argument is that pig's trotters contain collagen, which can make the skin more tender, smooth and elastic, so merchants have realized this and publicized it, and various small articles in the circle of friends have related descriptions. Over time, this has become a point recognized by the public.

First of all, I admit that collagen does have this effect. Pig's trotters also contain collagen, but the content is only a little lost, and the absorption rate of this part is still very low. Compared with the effect of long meat, it is a bit neglected.

I have a deep understanding of this. My mother used to let me drink water all the time, and she bought a large glass for me to drink eight cups a day. I will drink water as long as I have nothing to do. Drinking more is better than drinking less. But the result is only one, frequent use of the toilet, every day is saturated with water.

Water is the source of life, and it is really inseparable. But the mass of human body varies from person to person, and there is no fixed value. It is not that the more water you drink, the better. Ordinary people only need to drink 1, 000- 1, 500 ml, just like many people who are ill, they can't drink much water. There is a simple way to tell, that is, look at the color of your urine.

Many people are biased against monosodium glutamate, which is also the reason. Later, chicken essence came out, and merchants advocated that chicken essence was healthier than monosodium glutamate. Chicken essence is extracted from chicken. Later, with all kinds of vegetable chicken essence, the merchants shouted even more cool.

Is that really the case? To tell you responsibly, all wet, chicken essence has nothing to do with chicken, and its refreshing effect is the same as that of monosodium glutamate, except that monosodium glutamate is pure sodium glutamate, and other additives are added to chicken essence. What do you mean? In other words, chicken essence is monosodium glutamate with low purity and the ingredients are the same.

Both monosodium glutamate and chicken essence can be safely eaten. The seasoning effect of monosodium glutamate is better than that of chicken essence, but don't be greedy for family consumption. In addition, common condiments such as soy sauce and soy sauce also contain monosodium glutamate.

I thought so. I practiced for a while. Later, I learned that yogurt should not be drunk immediately after meals. Unless you are only 60% or 70% full, drinking yogurt after a full meal will not only increase the burden on your stomach, but also make you feel more flustered. Apart from gaining a few pounds, it won't make any difference at all. If you really want to drink yogurt, you can drink it 1 hour after meals.

How many of these five expressions have you used? Do you think these statements are correct? Can you believe it? Do you know any other sanitary habits that seem reasonable but are of little practical use?
