Red wine can prevent food poisoning
Research shows that red wine can combat potentially-fatal food poisoning bugs.
E coli, Salmonella and Listeria are all susceptible to the effects of red wine, and Helicobacter pylori, a stomach ulcer-causing bug which is spread through food and drink, is particularly vulnerable.
The study, carried out at the University of Missouri in the US, showed that Cabernet, Zinfandel and Merlot are particularly effective in fighting food-borne bugs.
White wine, however, has no effect.
The researchers told a Chicago conference that their findings added to mounting evidence about the health benefits of a glass or two of red wine.
Dr Azlin Mustapha, a food scientist, said: "Our study is a little different than those previously reported."
Those studies promote moderate red wine consumption for cardiovascular diseases.
"We went a step further and asked: If red wine is already good for cardiovascular diseases, what about food-borne pathogens?
"If you get a food-borne illness and drink red wine, will that help decrease the symptoms a little bit?
"This study showed the pathogens were inhibited by red wine."
She said that although the alcohol in wine may act against the bacteria, other factors such as acidity may have an effect.
The chemical resveratrol, which is found in grape skins - which are removed when making white wine - is also thought to have an important role.
However,wine-lovers are warned not to overdo it.
Dr Mustapha said: "I wouldn't go out and keep drinking red wine to the maximum but the recommended consumption of wine is one glass of wine for women, and two glasses for men per day."
