The cheapest leaf in the Vietnamese market is a "precious medicine" to prevent cancer.

(Dan Tri) - Only a few thousand a bunch at the market, but green onions contain so many nutrients that nutritionists call this a precious medicine right in the kitchen.

In traditional markets, green onions cost only a few thousand a bunch, and are often placed together with herbs or spices.

Those seemingly ordinary green onions actually contain a storehouse of nutrients that science has been talking about for years. From immunity, cardiovascular, bones and joints to skin and vision, green onions leave a clear mark.

Immune power

Scallions are rich in vitamin C and vitamin A, two nutrients that are key to the immune system. Vitamin C acts as an antioxidant shield, helping the body fight viruses and bacteria, and also helps reduce the risk of infection during weather changes.

The natural compounds in green onions have mild antibacterial and antiviral properties, so the Vietnamese cold-relieving onion porridge is not only a folk remedy but also has a fairly clear biological basis.

Scallions contain allicin and quercetin, two active ingredients well known in cardiovascular research. They help reduce bad cholesterol and help regulate blood pressure.

When cholesterol levels and blood pressure are kept stable, the risk of plaque formation is also significantly reduced. Thanks to that, green onions become one of the spices that help protect the arteries and reduce the risk of cardiovascular diseases, from heart attacks to strokes.

Anticancer potential from the allium family

Scallions belong to the allium family of plants, which has been shown in many studies to help prevent cancer. The organic sulfur compounds in onions, especially allyl sulfide, have the ability to slow the growth of cancer cells and limit the enzymes that stimulate this process.

Published studies have shown that regular consumption of green onions may contribute to a reduced risk of stomach and prostate cancer.

Healthy digestive system

Scallions provide a significant amount of natural fiber. Fiber plays an important role in increasing intestinal motility, supporting waste elimination and helping to limit constipation.

The essential oils and warming properties of green onions also help stimulate digestive secretions, warm the stomach and improve flatulence. In traditional dishes, green onions are often added at the end, not only to enhance the flavor but also to help the body digest food more easily.

Strong bones and stable blood clotting

Many people are surprised to know that green onions contain a rich amount of vitamin K, an important nutrient in supporting calcium absorption. When the amount of vitamin K is adequate, the body will increase bone density, helping to strengthen bones and reduce the risk of osteoporosis.

This vitamin also plays an essential role in blood clotting, helping wounds heal faster.

Good for eyes and improves skin quality

Green onions contain vitamin A, lutein, and zeaxanthin, three nutrients that are well-known in research on eye health.

Vitamin A helps protect the retina and limit macular degeneration, while lutein and zeaxanthin act as natural filters against blue light and other harmful agents to the eyes.

For the skin, vitamin C in green onions helps promote collagen production, increase elasticity and make the skin younger and healthier. At the same time, vitamin C also limits the effects of free radicals, a factor that causes premature aging of the skin.

Supports blood sugar control, good for people at risk of diabetes

The sulfur compounds in green onions have been shown to improve insulin sensitivity, helping the body use blood sugar more efficiently.

Some studies show that regularly adding green onions to meals can help stabilize blood sugar, adding a natural option for those looking to prevent or control diabetes.
