Onions is an awesome vegetable that is highly nutritious to the body and it’s highly consumed By the world at large.
Here are some health benefit and uses of Onion.
As per a study conducted by the University of Guelph, red onions are the most effective in destroying breast and colon cancer cells . These onions have high levels of quercetin and anthocyanin – two compounds that contribute to this characteristic. Onions activate the pathways that provoke the cancer cells to kill themselves. They make the environment unfavorable for cancer cells to communicate, and this inhibits their growth.
It was also found that people with the highest consumption of onions had the lowest cancer rates (4). As a preventative measure, you can have your burgers garnished with red onions.
Maintain Bone Health
Preliminary research suggests that onions can prevent age-related osteoporosis. According to Swiss researchers, a compound in white onions (called GPCS) can reduce bone loss . Though the study was conducted on rats, it does hold promise for humans.
Another study revealed that women who ate onions regularly had 5 percent more bone mass than those who ate less.Onion consumption was also found to have a beneficial effect on the bone density of women older than 50 years.
According to the Arthritis Foundation, quercetin in onions can inhibit the activity of leukotrienes, prostaglandins, and histamines (all of which cause inflammation) in osteoarthritis and rheumatoid arthritis . Onion intake was also found to help treat joint pains.
Prevent Inflammation And Other Allergies
We have already seen quercetin (and other flavonoids) in onions can help prevent inflammation. Onions also treat allergies by preventing the cells from releasing histamine.
Cooking with onions can help open and drain your sinuses. And the antihistamine properties of quercetin can also aid in reducing nasal congestion . Even eating a raw onion at night can help relieve congestion – the sulfur-compounds in the onion can break down the mucous.
Onions also possess antibacterial properties. As per one study, onion extracts acted against Streptococcus mutans and Streptococcus sobrinus, the bacteria responsible for dental caries and other allergies . Onions also possess antibiotic effects that can accelerate wound healing .
Onions contain chromium, which assists in regulating blood sugar.
- Relieve Tooth Disorders
Recent research shows that onions may kill bacteria that cause tooth decay and other dental problems. Chewing a raw onion for two to three minutes could kill all the germs in the mouth. Placing a small piece of onion on the affected tooth or bad tooth can also help in relieving toothache.
Lowers Blood Pressure: The sulfur in onions acts as a natural blood thinner and it prevents blood platelets from collecting. This is good for lowering blood pressure and preventing risk of heart attack or stroke, because you are more susceptible if blood platelets clog up. And remember quercetin? Of course you do. Well it also helps prevent plaque buildup in arteries which is also good for preventing heart attack and stroke.
Cure Ear Disorders
As per one report, though research is limited, most parents swear by onions to cure ear ailments. They insist that onion juice can work great to relieve earache. One way to do this is to heat up the onion, extract some of the juice, and pour a few drops into the infected ear. And this remedy, believe us, goes back to the 19th century.
All you need to do is place the onion in an oven at 450o F. Let it be for 15 minutes or until it becomes soft. Take out the onion – once it’s cool, cut it in half and squeeze the juice into a small bowl. You can strain the juice once, and using a medicinal dropper, pour a few drops of the juice into your infected ear.
An alternative is to place onion packs on the infected ear. Though the remedy is not scientifically proven, some people believe they might work .
- Lower Blood Sugar Levels
One study has proven that onion extract can help lower blood sugar levels. The study was conducted on diabetic rats, and the results were encouraging. One of the sulfur compounds in onions (S-methylcysteine) and quercetin can have beneficial effects on blood sugar. However, it was found that onions exhibited the positive effect only when taken along with metformin, the antidiabetic drug.
In yet another study, polyphenols (especially the ones in onions) were found to play a role in glycemic control
