Leek is rich in potassium, vitamins and other elements, which can improve the balance of potassium and sodium in the body, promote appetite and reduce blood fat, and inhibit the absorption of cholesterol in food, and has certain curative effects on hypertension, coronary heart disease and hyperlipidemia. Stimulate urination and eliminate excess water in the body.

Step 2 prevent constipation

Leek has the reputation of "king of green vegetables" and is rich in cellulose. Every 100g of leek contains cellulose 1.5g, which can stimulate intestinal tract, enhance intestinal peristalsis, promote the formation of feces, and excrete excess nutrients in the body with feces in time, which is beneficial to prevent intestinal cancer and habitual constipation. In addition, these fibers can also wrap the gravel, hair and metal chips in the digestive tract and excrete them with feces. Therefore, it is called "intestinal grass".

3, sterilization and anti-inflammatory

Sulfide contained in leek leaves can inhibit and kill bacteria, and has inhibitory effects on Staphylococcus, Escherichia coli, Proteus and Pseudomonas aeruginosa. Therefore, eating more leeks can sterilize and improve the body's immunity.

4. Anti-fatigue effect

Leek contains alliin, which can be converted into allicin and combined with vitamin B 1 to produce allithiamine. Garlic thiamine has the same physiological activity as vitamin, which can accelerate the decomposition of lactic acid (fatigue substance), so it has anti-fatigue effect.

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 prevent and treat 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.

Leek is a kind of mixed food for many people. I like its taste, but I'm worried that my stomach will be upset after eating it. There is a famous saying in Zhou Qing of Southern Qi Dynasty: "Early spring and early leek, late autumn and late leek", and this "leek" is naturally leek. The quality of leeks in early spring is the best, followed by late autumn and the worst in summer. There is a saying that "Spring vegetables smell sweet and Natsuna stinks".
