Chinese medicine says that Chinese chives can also benefit the liver and strengthen the stomach: Chinese chives contain volatile essential oils, sulfides and other special ingredients, giving off a unique pungent smell, which is helpful for soothing the liver and regulating qi, stimulating appetite and enhancing digestion. Scrambled eggs with leeks, leek pancakes and leek jiaozi are all very good.
There are two kinds of leeks on the market: wide leaves and narrow leaves. Narrow leaves are slender, dark in color, high in fiber and strong in fragrance. Broad-leaved leek leaves are broad, pale, tender and slightly tasteless. When buying, you can choose leeks with wide and narrow leaves according to your personal preference. Don't buy leeks with yellow leaves and insect eyes.
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.
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 the Southern Qi and Zhou Dynasties: "Chives are early in spring and long in autumn". 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".
Leek, also called Cao Yang, is very delicious and has a unique fragrance. The unique pungent smell of leek is formed by its sulfide, which has certain bactericidal and anti-inflammatory effects and is helpful to improve human immunity.
These sulfides in leek can also help the human body absorb vitamin B 1 and vitamin A, so leek is a more nutritious way to eat with pork food rich in vitamin B 1. However, sulfides are volatile when heated, so it is necessary to quickly turn the wok when cooking leeks. If you heat it too much, you will lose the flavor of leek.
