White onion benefits

Gives you bad breath! But onion is said to be one of natures Viagra. Yes yes, I am not kidding. But whether it actually works or no is still a doubt. But many people say that half an onion before sex can make your sexually capable. But remember eating a raw onion is not good for your breath and you might have to wash it out with listrine or something like that. Lol. But in any case you shouldn't eat it raw. At least bbq it on an open flame before and then eat it. Hope that answers your question.

The white onion is not as strong as its other allium family members, so it's often desired for its milder and sweeter taste. Though it has a lighter taste, it's also slightly lighter on vitamins and nutrients than other onions. Nonetheless, it's packed with health-boosting compounds.
*White onions contain compounds called flavonoids, which are known for anti-oxidant activity. One of the most powerful flavonoids in an onion is called quercetin which has been reported to stop the growth of cells of various cancers, such as lung cancer and stomach cancer.
*It is also rich in organosulfur compounds which help fight inflammation that is related to arthritis and asthma, and reduce diabetes symptoms.
*Manganese, copper, potassium, vitamin B6, folate and phosphorous help round out the health benefits packed into this powerful plant.
*If you're watching your weight, a half cup of raw onion on a salad or in a food dish only has 30 calories, but its benefits go far beyond your waistline.
