Leeks are nutritious and delicious, but these people had better not eat a single bite.

Leek is a kind of vegetable that many people like to eat, and leek seed has high nutritional value, such as tonifying kidney, invigorating stomach, refreshing, antiperspirant and astringent. In traditional Chinese medicine, some people call leek "intestinal lavage grass".

The main nutrients of vegetables are vitamin C, vitamin B1, vitamin B2, niacin, carotene, carbohydrates and minerals. With tonifying the kidney; warming in the middle of the qi; dispelling blood stasis; detoxification. The main kidney deficiency impotence; cold abdominal pain; choking diaphragm nausea; chest pain; dysentery; haemorrhage; hematemesis; urine blood; dysentery; hemorrhoids; carbuncle swelling toxin; lacquer sore; the effect of injury. However, patients with internal heat due to yin deficiency and ulcers and eye diseases all avoid food.

Leek is a happy and worrying food for many people. I like its taste, but I'm worried about my stomach after eating it. Although leek has a lot of benefits to the human body, it is not the more the better. The Compendium of Materia Medica once recorded: "if you eat more leek, you will be dim and dark, especially after drinking." Modern medicine believes that people with hyperactivity of yang and febrile diseases are not suitable for consumption. Leek has more crude fiber and is not easy to digest and absorb, so you can't eat too much leek at one time, otherwise a large amount of crude fiber stimulates the intestinal wall and often causes diarrhea. It is best to control it at 100g, 200g, not more than 400g.

These sulfides in chives can also help the human body absorb vitamin B1 and vitamin A, so if chives are matched with pork foods rich in vitamin B1, it is a more nutritious way to eat. However, sulfides are volatile in case of heat, so when cooking leeks, you need to stir-fry quickly. If you overheat a little, you will lose the flavor of leeks.

The climate in the north is different from that in the south, and chives can not be bought almost at any time like Hong Kong, only when leeks sprout in spring. This is the real leek, not baked with artificial cover of the sun, so the taste is very sweet and the price is very expensive. Northerners are eating spring rolls, the most fastidious is to use shredded meat fried chives as stuffing. The chives in the north are short and fat and tender, and they are not as long as those in Hong Kong. They are the treasures of garden vegetables.
