1, the misunderstanding of drinking soup for health preservation
Myth 1: It is better to drink more soup.
Some people drink too much soup for a long time, which is harmful to their health and even makes them sick. For example, bone soup, after boiling with water, dissolves a lot of bone calcium in the soup, which is cold. Drinking it in the stomach dilutes the gastric juice used for digestion, and the calcium in bone soup is not easily absorbed by the gastrointestinal tract, which is prone to symptoms of fullness, indigestion and even nausea. Broth is also not suitable for excessive drinking, because meat contains a lot of fat and will dissolve in hot soup during stewing. Drinking too much is easy to increase blood lipids and is not good for cardiovascular and cerebrovascular health. If people with high blood lipids want to supplement protein, they can use tofu and vegetable soup instead of broth.
Vegetarian soups such as cabbage soup, radish soup, seaweed soup and winter melon soup have the effect of clearing away heat and promoting diuresis. Some people feel that they are getting angry and drink too much for a long time. Drinking soup and urine is too much, and many body fluids useful to the human body are excreted with urine. The human body will lose weight, often feel dry mouth and drink more soup. But drinking soup will aggravate dry mouth and lead to the loss of body fluid.
Myth 2: The longer the stew, the better.
Generally speaking, it is advisable to boil soup for two hours, and the taste and nutrition should come out. Cooking for too long is unfavorable, which may easily lead to deterioration of protein. From the point of view of nutrition, it is not enough to supplement protein and minerals by drinking soup, and the longer the soup is cooked, the more vitamins are lost. On the contrary, fat will be partially or more dissolved in soup.
For example, some people usually put ginseng into the soup two or three hours in advance when making ginseng chicken soup, thinking that only in this way can all the nutrients of ginseng be dissolved in the soup. In fact, ginseng contains ginsenoside, which will decompose and lose its nutritional value if cooked for too long, so ginseng soup had better cook for about 40 minutes.
Myth 3. Drink soup without eating ingredients.
Many families stew soup in winter, such as chicken soup, mutton soup, fish soup and so on. Many people think that meat and other raw materials are cooked for a long time, and nutrients enter the soup. Drinking soup is more nutritious than eating materials. In fact, no matter how long it takes to cook the soup, the nutrition of the raw materials can't be completely dissolved in the soup, so even eating and drinking is the best choice.
There is an old saying in China that "the original soup is the original dish". It is said that the combination of soup and soup ingredients can make the nutrition more adequate and the conditioning function more effective. Because all the nutrition of soup comes from raw materials other than water. So it seems that the boiled soup is already very thick, but in fact, the nutritional components of the soup are less than 10% of the total raw materials. For example, it used to be thought that bone soup can supplement calcium, but in fact, calcium phosphate in bones is difficult to dissolve into soup. Even a thick bone soup contains only 2-20 mg of calcium in an average of 100 ml, while the human body needs 800 mg of calcium a day. After boiling for a long time, the remaining raw materials are not the best in taste, but the peptides and amino acids in them are more conducive to human digestion and absorption.
Myth 4: Drink too hot soup.
Drinking too hot soup is harmful and useless, and drinking soup below 50℃ is more appropriate. Some people like boiling soup. In fact, people's mouth, esophagus and gastric mucosa can only tolerate the temperature of 60℃ at most, which will cause mucosal burns. Although the human body has the function of self-repair after scalding, repeated injuries can easily lead to malignant transformation of the upper digestive tract mucosa. After investigation, it was found that people who like to drink hot food have a high incidence of esophageal cancer.
Myth 5: Old hen stew is more nutritious than chicken.
People often say that old hen stew is the most nutritious. In fact, as far as nutrition is concerned, the old hen is not taller than the chicken, but the stewed taste is stronger and better. This is because the nutrition of chicken mainly exists in protein and fat, and the contents of these nutrients in old hens and young chickens are similar. Because the old hen has a long growth period, its meat contains more nitrogen-containing extracts such as creatinine and creatine, so the stewed chicken soup tastes fresher. However, the nutritional value of these nitrogenous extracts is not high.
It's time for soup.
1. Have soup before meals
As the saying goes, "soup before meals is better than good medicine", which is scientifically justified. This is because, from the mouth, throat, esophagus to the stomach, it is like a passage, which is the only way for food. Drinking a few mouthfuls of soup before eating is equivalent to adding some "lubricants" to this digestive tract, so that food can be swallowed smoothly and hard objects can be avoided to stimulate the mucosa of the digestive tract.
At the same time, drinking soup before meals has another function, that is, it can enhance people's satiety, so that they will not have a desire for food, and it is very effective in absorbing heat energy. A bowl of soup before meals can absorb about 100- 190 calories, which is a good choice for beauty lovers.
Drinking soup before meals can effectively reduce the absorption of food, and at the same time, soup can supplement the nutrients needed by the human body, which can not only provide nutrition, but also keep fit. Not good?
2. Drink soup after meals
Drinking soup after meals is beneficial to the digestion and absorption of food, and is suitable for people with nutritional deficiency such as weak digestive function and the elderly with poor physique. Drinking soup after meals is helpful to aid digestion and absorption and supplement nutrition.
Therefore, some nutritionists believe that developing the habit of drinking soup continuously before or during meals can also reduce the occurrence of diseases such as esophagitis and gastritis. At the same time, it is also found that people who often drink all kinds of soup, milk and soybean milk are also the easiest to keep the digestive tract healthy.
Drink soup between meals.
It is also good to drink soup from time to time. Because it helps to dilute and stir food, it is beneficial to the digestion and absorption of food in the gastrointestinal tract. If you don't drink soup before meals, you will be thirsty after meals because of excessive secretion of gastric juice. Drinking water at this time will dilute gastric juice and affect the absorption and digestion of food.
4. Have soup at noon
Which meal is more suitable, soup, breakfast, lunch or evening? Some experts pointed out that "eating soup at lunch absorbs the least calories", so in order to prevent obesity, you might as well choose to eat soup at noon. It is not advisable to drink too much soup for dinner, otherwise the quickly absorbed nutrients will accumulate in the body, which will easily lead to weight gain.
