Soups, especially chicken soup, fish soup and bone soup, are often closely related to words such as "nutrition" and "delicacy" in many people's impressions. In many families, every once in a while, my mother will cook a pot of white and thick soup to make up for the children and the elderly at home, and even specially say, "Drink more soup, it is nutritious." Did you really cook all the nutrients in the meat into soup after thousands of stews? Dr. Xu Jiechao, a nutritionist at Jiangsu Hospital of Integrated Traditional Chinese and Western Medicine, told reporters that the truth may disappoint many well-meaning mothers.

Milk-like broth is definitely not rich in nutrition.

Fish, ribs, chickens, ducks and other ingredients, after careful cooking by chefs, often turn into milky soup, which is delicious and memorable. People often take it for granted that such a rich broth must be nutritious. However, nutritionist Xu Jiechao told reporters that behind food, it is often not nutrition, but "fat".

"Studies have shown that there are very few nutrients in broth, mostly fat and purine, and the actual nutrition may not be as good as that in meat110." Nutritionist Xu Jiechao said that protein in meat, especially lean meat such as chicken and pork, is mostly composed of muscle fibers, which is difficult to dissolve.

Nutritionist Xu Jiechao further explained that the reason why the broth is delicious is that some short peptides such as free amino acids are dissolved in the stew process. "For example, glutamic acid may combine with seasonings added in the process of boiling soup to form sodium glutamate, which is the main component of monosodium glutamate, so I feel the soup is very fresh when I drink it." In addition, the stew has the same color as milk, which is actually because of the fat.

In fact, it is unscientific to stew for thousands of times.

Many people think that the more "stock" and "stock", the more nutritious it is. Therefore, we must pay attention to boiling soup for thousands of times. The longer the time, the better. Xu Jiechao nutritionist told reporters that this is a common misunderstanding.

Different ingredients have their own peaks and take a long time to cook. After reaching the peak, some substances will gradually evaporate and nutrients will be lost. Nutritionist Xu Jiechao said that some water-soluble ingredients, such as water-soluble vitamins, will enter the soup from the ingredients with cooking. The longer the time and the higher the temperature, the more they will be lost.

So how long is it appropriate to stew the common ingredients in soup under normal circumstances? Xu Jiechao, a nutritionist, told reporters that general chicken soup can be stewed for 1 hour to 1.5 hours; The time of pig bone soup may be a little longer, but not more than 2 hours; Fish is easier to cook, and it can be done in about half an hour.

If you want to drink soup healthily, you must pay attention.

Nutritionist Xu Jiechao told reporters that the broth contains a lot of fat and purine. Patients with high urea may induce gout if they take too much for a long time. For people who want to lose weight, drinking soup often makes them fatter and fatter. For people with three highs, drinking a lot will increase calorie intake, which is not conducive to controlling blood sugar and blood lipids. In addition, seasoning will be added when stewing soup, and the salt content is relatively high. Drinking too much soup may also affect the stability of blood pressure. Therefore, people with three highs and high uric acid or those who need to lose weight should drink less broth and drink vegetable soup appropriately.

"In fact, soup is more suitable for patients or women recovering after surgery. Some patients who have poor digestive function and can't eat anything can also drink a little broth in moderation, but it is best to drown chickens and ribs. Before cooking the soup. Skim off the oil slick on the surface. " Nutritionist Xu Jiechao suggested that when cooking soup, try not to put oil and less salt, and it is best to drink soup before meals. Drinking a little soup before meals can lubricate the intestines, promote digestion, enhance satiety and reduce calorie intake. "It is not recommended to drink too much soup after a meal. Drinking too much soup after a meal will dilute the digestive juice and affect the digestive function of the human body. " Xu Jiechao nutritionist stressed.
