Scientists Discover Influenza's Achilles Heel: Antioxidants 
In an article appearing in the November 2009 print issue of the FASEB Journal, they show that antioxidants -- the same substances found in plant-based foods -- might hold the key in preventing the flu virus from wreaking havoc on our lungs.
"The recent outbreak of H1N1 influenza and the rapid spread of this strain across the world highlights the need to better understand how this virus damages the lungs and to find new treatments," said Sadis Matalon, co-author of the study. "Additionally, our research shows that antioxidants may prove beneficial in the treatment of flu."
Matalon and colleagues showed that the flu virus damages our lungs through its "M2 protein," which attacks the cells that line the inner surfaces of our lungs (epithelial cells). Specifically, the M2 protein disrupts lung epithelial cells' ability to remove liquid from inside of our lungs, setting the stage for pneumonia and other lung problems. The researchers made this discovery by conducting three sets of experiments using the M2 protein and the lung protein they damage.
