The following is one of them. For details, please refer to cancer network's dietotherapy column:/aizhengshiliao.asp.
As the saying goes, "soup before meals is better than good medicine", which is scientifically justified. Preventing cancer requires a healthy lifestyle, and drinking soup is one of them.
Drinking soup can prevent cancer. 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 (or a little water) 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. It is also beneficial to drink soup from time to time with meals. 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 the gastric juice and affect the absorption and digestion of food. Therefore, some nutritionists believe that developing the habit of drinking soup often before meals can also reduce the occurrence of esophagitis and gastritis. At the same time, it is found that people who often drink all kinds of soup, milk and soybean milk are also the easiest to keep the digestive tract healthy.
There are two references to whether a person's diet is reasonable. One is the body mass index. No matter how much you eat, as long as the body mass index exceeds the standard, then the diet must be unreasonable. The second reference standard is body shape. For people who are also overweight, the risk of obesity in apple shape is much higher than that in pear shape.
The most scientific way to lose weight is to drink soup before meals. The best example is Cantonese, who just like to drink soup before meals. Because the soup enters the stomach, especially the old fire soup in Guangdong, it takes a long time to stew, and once it reaches the brain through the nerve reflex in the stomach, the appetite automatically drops, the time is longer, and the eating speed is slower. As long as you drink soup before meals, you will automatically eat less. Northerners, on the other hand, get fatter after drinking soup. If you drink enough soup, your stomach will be full, and soup, sliced meat and oil will increase a lot of calories.
It's different to soak in dry rice or hard steamed buns when eating. Because when we chew food, we not only have to chew it up to swallow it easily, but more importantly, we have to moisten it with saliva, which is produced by continuous chewing. Saliva contains a variety of digestive enzymes, which have physiological functions such as helping digestion, absorption and detoxification, and are very beneficial to health. And the soup for soaking rice is full of water. Soft and easy to swallow, people are often lazy to chew and swallow food quickly without saliva digestion, which increases the digestive burden of the stomach. Over time, it is easy to cause the attack of stomach trouble. Therefore, it is not advisable to drink soup and soak rice often.
Of course, drinking soup before meals is good for your health. Doesn't mean it's good to drink too much. It varies from person to person, and you should also master the time of drinking soup. It is generally advisable to use half a bowl of soup before lunch and dinner, and more before breakfast, because after a night's sleep, the human body loses more water. The time to drink soup is about 20 minutes before meals, or you can drink soup slowly and in small quantities. In short, the comfort of the stomach is the key to drinking soup, and "binge drinking" is forbidden before and after meals.
