Onions are rich in nutrients, including potassium, vitamin C, folate, zinc, selenium, and fiber, as well as two special nutrients — quercetin and prostaglandin A. These two special nutrients give Onions health benefits that cannot be replaced by many other foods.
1. Prevent cancer
Onion’s cancer-fighting benefits come from its high levels of selenium and quercetin. Selenium is an antioxidant that stimulates the body’s immune response, which inhibits the division and growth of cancer cells. It also reduces the toxicity of carcinogens. Quercetin, on the other hand, inhibits carcinogenic cell activity and prevents cancer cell growth. In one study, people who ate Onions were 25 percent less likely to develop stomach cancer and 30 percent less likely to die from stomach cancer than those who didn’t.
2. Maintain cardiovascular health
Onions are the only vegetable known to contain prostaglandin A. Prostaglandin A dilates blood vessels and reduces blood viscosity, thus lowering blood pressure, increasing coronary blood flow and preventing thrombosis. The bioavailability of quercetin, which is abundant in Onions, suggests that quercetin may help prevent the oxidation of low-density lipoprotein (LDL), providing an important protective effect against atherosclerosis, scientists reported.
3. Stimulate appetite and help digestion
Onions contain allicin, which has a strong aroma and often causes tears when processed because of its pungent smell. It is this special smell can stimulate stomach acid secretion, increase appetite. Animal experiments have also proved that onion can improve gastrointestinal tension, promote gastrointestinal peristalsis, so as to play an appetizing role, on atrophic gastritis, gastric motility, dyspepsia caused by loss of appetite has a significant effect.
4, sterilization, anti-cold
Onion contains plant fungicides such as allicin, has a strong bactericidal ability, can effectively resist influenza virus, prevent cold. This phytonidin through the respiratory tract, urinary tract, sweat glands discharge, can stimulate the cell duct wall secretion in these locations, so it has expectorant, diuretic, sweating and antibacterial and antiseptic effect.
5. Onions are good for preventing “affluenza”
It is used for headache, nasal congestion, heavy body, aversion to cold, fever and no sweat caused by external wind cold. For 500ml Coca-Cola, add 100g onion and shred, 50g ginger and a small amount of brown sugar, bring to a simmer for 5min and drink while hot.
