World Amazing Stuff: Tearless onions

Tearless onions

Scientists have developed a new type of 'tearless' onions which produce less protein.
Scientists say the 'tearless' onions not only prevent eyes from burns and tears, but also fight against cardiovascular disease and weight gain.

Researchers Colin C Eady and colleagues noted that the onion has a unique chemistry that leads to its tear inducing effects when cut. The scientists found that in lab tests, extract from the tearless onion significantly reduced platelet clumping, compared to regular onions or even garlic.

According to the study published in The American Chemical Society's Journal of Agricultural and Food Chemistry, the tearless onion could help control weight gain as regular onions or garlic. Many people eat garlic cloves or take it as a nutritional supplement in pill form to reduce the clumping of platelets in the blood, which can lead to blood clots and clogged arteries. Results showed that the new onion has about the same anti-inflammatory properties as the original.
