scientists create tearless onions which is heart-friendly and manage to gain weight.

WASHINGTON, US: Onions, a key ingredient in recipes around the globe, come in a tearless version that scientists are now reporting could pack health benefits like, garlic, which is renowned for protecting against heart disease. The report was published in ACS’ Journal of Agricultural and Food Chemistry. The laboratory analysis suggests a heart-friendly role for the tearless onions, as well as a possible role in managing weight gain.

Researcher Colin C Eady and colleagues noted that the onion has a unique chemistry that leads to its tear-inducing effects when cut. Its pungency has driven cooks to don goggles, clench wooden spoons in their mouths and try other usually futile techniques to prevent crying at the cutting board. An answer could arrive in the form of a new type of onion that makes less of the protein blamed for making eyes burn and tear up.

Eady’s team has developed such a version, which instead makes a sulfur compound similar to one found in cut garlic that may be the key to its cardiovascular benefits. 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. Garlic also has been shown to reduce weight gain. They wanted to know whether the new onion might also have similar positive effects on health.

The scientists found that in lab tests, extract from the tearless onion significantly reduced platelet clumping, compared to regular onions or even garlic. Other results showed that the new onion had about the same anti-inflammatory properties as the original. Also, preliminary testing in rats showed that the tearless onion could help control weight gain - more so than regular onions or garlic.
