Our resistance to one of the deadliest forms of cancer may be helped by a glass of wine. The rate of esophageal adenocarcinoma in the U.S. has increased 500% over the last thirty years. It’s a subtype of esophageal cancer triggered by acid reflux which causes Barrett’s Esophagus, a transformation of the cells in the esophagus to the type found in the stomach.

The findings are reported in the March issue of the journal Gastroenterology. One study determined just one glass of wine per day reduced the incidence of Barrett’s esophagus by 56%. The study was conducted by pharmaceutical maker Kaiser Permanente.
