Extended data:
The main nutritional components of leek are vitamin C, vitamin B 1, vitamin B2, nicotinic acid, carotene, carbohydrates and minerals. Leek is also rich in cellulose. The content of cellulose in leek per 100g is higher than that in onion and celery. It can promote intestinal peristalsis, prevent the occurrence of colorectal cancer, reduce the absorption of cholesterol, and play a role in preventing and treating diseases such as arteriosclerosis and coronary heart disease.
Although leek has many benefits to human body, not the more the better. Compendium of Materia Medica once recorded: "Eating more leeks makes people dizzy, especially after drinking." Modern medicine believes that people with hyperactivity of yang and febrile diseases are not suitable for eating. Leek contains a lot of crude fiber, which is not easy to digest and absorb, so you can't eat too much leek at a time, otherwise a lot of crude fiber will stimulate the intestinal wall and often cause diarrhea. The appetite should be controlled at 100~200g, not more than 400g.
