You've already heard how good the onions are for you.
Onions are a great detoxification aid for your blood and liver and the sulphur-containing amino acids (methionine and cystine) in them actually help remove heavy metals, as well as protect against mercury, cadmium and lead toxicity. That's pretty powerful stuff. When you come across foods like onions and garlic, which can fight heavy metals, you can be sure they are capable of protecting you from virtually anything. Including cancer. The antioxidants in onions help reduce your cells' DNA damage caused by free-radicals and work to kill tumour cells even when they are already present. In addition to that, just one medium onion is an excellent source of your daily needs for Vitamin C, B6, B1, K, biotin, chromium, calcium, dietary fibre and folic acid- everything you need for clean, clot-free blood with lowered sugar levels. It's not by chance that cut into halves, the onion rings look like blood cells under a microscope. Nature provides all the clues. Source: Foods Healing Power
But why do they have to make you cry?
As you chop up an onion, it releases lachrymatory-factor synthase enzymes, which then react with the sulfoxides. More chemical reaction occurs and as it enters the air and travels towards our eyes, it triggers nerve endings in the cornea to communicate with the brain stem. The brain registers the irritation in the eye then alerts the lachrymal gland to stimulate tear production to flush away the invader. Here comes the 'waaaaaaa'. This is in no way a bad thing, as it's another way for the onion to act as a cleanser and flush out our eyes. Source: How Stuff Works
I don't care about the WHY, just make it stop.
I've recently read the news about a genetically modified onion, which won't cause tears. Scientists in New Zealand (oh why NZ, why?) have developed a way to isolate and handicap the lachrymatory enzyme, which won't undergo the chemical reaction when you cut the onion, producing tear-free chopping freedom. You'd never guess what the trick is to this 'invention'! It's all about making the soil it grows in low in sulphur! The exact stuff mentioned above, which prevents cancer and protects you agains heavy metals has to be taken out of the soil for what now seems to be no longer an onion, but a by-product of it.

That's not cool with me...
So I asked you guys on Facebook to share your tricks to stop the tears, when you cut 'real' onions. Some answers made me crack up, but hey, they do make sense! And if they work, why not put on some goggles, clench a spoon between your teeth and cut the onions in a swimming pool of water? :)
- Tami Stingley My eyes don't water when I use sweet onions (like vidalia) and get them out of the cellar (they are cool and that helps, can also refrigerate if don't have one, as freezing makes them mushy) Cut the exposed end away from you. Also heard that cutting near a stove hood fan helps.
