Edible benefits of onions

Lower blood lipid

At the same time, the sulfur-containing compounds in onions can enhance the activity of fibrinolysis, and can also lower blood lipids and resist arteriosclerosis.

Promote digestion and cure constipation

Onion is spicy and rich in dietary fiber, which can stimulate the gastrointestinal tract to secrete digestive juice, promote gastrointestinal peristalsis, and has the effects of promoting digestion, increasing appetite and preventing constipation.

Sterilization and anti-cold

Allicin and sulfur-containing compounds contained in onions have strong bactericidal ability. These components can resist influenza virus, resist cold and sweat, inhibit bacteria and prevent colds. At the same time, these ingredients also have expectorant and diuretic effects.

Refreshing

The allicin and sulfur-containing volatile substances in onions can stimulate the lacrimal glands to secrete tears. This is also the reason why cutting onions will cause tears. These ingredients can promote metabolism, eliminate fatigue, and have a refreshing effect.

Hypoglycemic

Onions contain a substance that can stimulate the synthesis and release of insulin. The effect of this ingredient is similar to that of oral hypoglycemic drugs (metasulfame) and has a significant effect on lowering blood sugar.

Anti-cancer

The selenium and quercetin in onions can inhibit the activity of cancer cells and prevent the division and growth of cancer cells. At the same time, they can also reduce the toxicity of carcinogens and have anti-cancer and anti-cancer effects.
