Based on the results of this study, researchers
suspect the high content of the compound resveratrol in red wine plays a
key role. Resveratrol is an anti-fungal chemical that occurs naturally
under the skin of red wine grapes.
Joseph C. Anderson, M.D, and his colleagues at
Stony Brook University in New York, compared the drinking habits of 360
red and white wine drinkers with similar lifestyles to examine the
prevalence of colorectal neoplasia.
They found that red wine dramatically reduced the
risk of colorectal neoplasia (colon cancer) by 68 percent but white wine
did not.
The resveratrol content of wine is related to the
length of time the grape skins are present during the fermentation
process.
The concentration is significantly higher in red
wine than in white wine, because the skins are removed earlier during
white-wine production, lessening the amount that is extracted,
explained Joseph C. Anderson, M.D.
Dr. Anderson says a healthy lifestyle is essential
in cutting the risk of colorectal neoplasia, and he does not advocate
drinking red wine if you do not drink currently.
Although alcohol consumption increases the risk for
colorectal neoplasia, researchers say this study suggests wine may have
a protective effect. Further, studies suggest that resveratrol may exert
chemopreventive properties on colon cancer cells.
