Leek and beef are both foods that help heat and make a fire. Beef is warm, invigorating qi and helping fire. Leek is a fragrant and warm product, so it can't be eaten together.

If beef is cooked and eaten with leeks, it will easily help to get angry, leading to oral inflammation, swelling and pain, aphtha and so on.

Beef+orange is not conducive to the absorption of nutrients.

Nutritional components of leek

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, and the cellulose content per 100g of leek is 1.5g, which is higher than that of scallion 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".

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.
