Why onions make you cry?

Thats a very good question, I suffer so much when peeling onions although my mother could peel so many onions and they never made her cry at all, I used to make relish years ago and I used to get my mother to peel all the onions...

the juices in the onion seem to start burning yours eyes when you start cutting the onion.The red onions are the worst to cut,they have the strongest juices.I can't bare to cut an onion.It hurts.

They absorb sulfur from the ground and your tear glands start producing as a reflex to the liberation of these sulfur particles when you cut the onion. What also has this is garlic chives leeks and about 300 other specimens relative to these.

when you cut unions, it will release some gas to air, it more like self defense. i don't know exactly what is gas name.

The one and only vegetables that enable everyone cry is onion, sometimes funny feeling, a such type of vegetables can make make us cry without any reason. Funny right. Perhaps, i will feel good if there is vegetable that can make everyone smile There is also benefit silently angry and continue appreciate.

I think it is common, because red onions contain sulfur, which makes us distracted eyes and nose, but I heard crying is good for health while not excessive, since remove toxins in the body through the tears. happy mylotting and be healthy!!

My grandparents believe that when you cry whenever you peel and chop onions, you'll also cry when you're already married. They say you'll not have a good relationship with your in laws. That's the sign. If onions can't make you cry, your in laws for sure really like you, and you're the one who will make them cry. That's of course superstitious belief, but they always say it's true. Well ... find it for yourself. Aside from this, another superstitious belief with regard to onion is the use of coarse salt. They say if you put salt on the chopping board, you'll not cry while you chop onions. But we found out that it's not superstitious belief, it's true! Do you also cry when you peel and chop onions? I tell you, this is very effective. Put at least one tablespoon of salt on the corner of the chopping board. It shouldn't be mixed with the onion. Just let the salt stay there. We haven't tried yet if iodized salt is also effective. I also read in one site that if you peel and chop onions in front of electric fan, you'll not also cry, instead the electric fan is the one that is going to cry. So, which is your choice? Salt or electric fan?
