Researchers at the University of Leicester will present findings that one glass of wine a day could prevent bowel cancer.
Resveratrol, a plant chemical, is found in the skins of grapes and concentrated red wine.
Scientists have known for some time that the chemical has anti-cancer properties and benefits to diabetes and heart disease patients.
The new research has shown that the amount needed to help fight bowl cancer can be consumed in one large glass of wine or two small glasses.
Five milligrams is the recommended amount.
Scientists found that the low dose was more potent that the higher does of one gram.
