166 Onions Make Me Cry

The tasty flaky onion is a very interesting vegetable whose roots run as deep as human history. This little vegetable originated in Asia and soon made its way to every corner of the globe in every single dish one can think of. The ancient Egyptians worshiped the onion because they believed that its round shape and inner concentric rings represented eternity. Onions if you havent noticed will make you cry if you chop one of them up. Well that is because of sulfenic acids released when one cuts the vegetable. The sulfenic acids affect open nerves found on the cornea wich sends messages to the brain saying that the eye is burning. The brain then reacts by turning on the tears to wash the irritant away. Onions do contain many good things that help prevent and cure a slew of diseases found in humans. You will never think of the onion the same way again.
