What makes garlic good for you? (Chris Ramirez for The New York Times)
Garlic has long been touted as a health booster, but it’s never been clear why the herb might be good for you. Now new research is beginning to unlock the secrets of the odoriferous bulb.
In a study published today in the Proceedings of the National Academy of Sciences, researchers show that eating garlic appears to boost our natural supply of hydrogen sulfide. Hydrogen sulfide is actually poisonous at high concentrations — it’s the same noxious byproduct of oil refining that smells like rotten eggs. But the body makes its own supply of the stuff, which acts as an antioxidant and transmits cellular signals that relax blood vessels and increase blood flow.
In the latest study, performed at the University of Alabama at Birmingham, researchers extracted juice from supermarket garlic and added small amounts to human red blood cells. The cells immediately began emitting hydrogen sulfide, the scientists found.
The power to boost hydrogen sulfide production may help explain why a garlic-rich diet appears to protect against various cancers, including breast, prostate and colon cancer, say the study authors.
