Newsweek reported in May 99 that a study showed how wine helps prevent ulcers. In a study of 1800 people, the scientists tested for the presence of helico bacterpylori, which causes ulcer infections. Compared to non-drinkers, those who had one glass of wine a day had 7% fewer of these bacteria.

Those who drink two glasses a day had 18%, and those who drank 3 or more glasses had 1/3 fewer bacteria.
