Onions
If you slice an onion, and it makes you cry, rejoice! According to some studies, those compounds that bring tears to your eyes are called thiosulfinates and could keep you from having a stroke.
Thiosulfinates act as a natural blood thinner and keep blood platelets from clumping. In addition, the quercitin in onions has been shown to relax and dilate blood vessels, which also aids in stroke prevention.
It’s important to note that none of these veggies are still healthy if you cook them for a long period of time in butter or a fatty oil. Staying true to their God-given properties is best.
Onions are high in vitamin C, and provide calcium, iron, folic acid, and dietary fiber. And, because they can kill the H pylori bacteria, they may also help to prevent—but not treat—stomach ulcers.
