Where is the nutritional value of onions? Are green onions? what are the nutrients of green onions?

Many people think that green onions are green onions, but they are not. There is a difference between the two. Do you know the nutritional value of onions? Let's take a look.

Green onions contain calcium, vitamin C, β-carotene, dietary fiber and other nutrients. 100 grams of green onions contain 3.5 grams of dietary fiber, which is a high-fiber vegetable. In addition, the epidermal cells of green onions contain a large number of germicidal onion, malic acid, phosphate sugar.

Green onions contain trace element selenium that can stimulate digestive juice secretion and increase appetite, while green onions contain prostaglandin A, which can promote blood circulation, help perspiration and diuresis, thus prevent dizziness caused by elevated blood pressure, and also help to prevent senile dementia. In addition, the pungent odor of onions, a volatile ingredient of allicin, can be antibacterial and sterilized, help reduce phlegm and relieve sore throat. When cooking high-protein foods, adding a small amount of onions can improve the body's absorption of protein.

Allicin in onions will slightly stimulate the secretion of glands, causing perspiration, so sweaty people are not suitable to eat onions. Although the nutrition of raw onions is relatively high, they will inevitably be contaminated with bacteria, parasites and even pesticides when planting, so they must be cleaned again and again before eating raw onions.

The parts of onion leaves contain β-carotene, vitamin C and calcium, and the nutrients are much higher than those of onion white.
