r levels are much higher in red wine than in white.
For Western men and women lung cancer is the second most prevalent cancer, though worldwide it is first. This too has been the subject of a study about wine. Spanish researchers in 2004 found that, once again, red wine was linked to a reduced risk, while white wine was linked to a 鈥渧ery slight but significant鈥?increase in risk. Published in the British medical journal, Thorax, this was one more indication that the specific nutrients linked to the skin and seeds of grapes鈥攚hich give red wine its color鈥攁re fundamental to its benefits.
According to the World Health Organization, over 900,000 new cases of colorectal cancer occur annually, making it the third most common cancer on the planet. In 2006, researchers at Stony Brook University in New York found that red wine reduced the risk of colorectal neoplasia (pre-cancerous lesions) by 68 percent. White wine had no effect. Those who drank beer or other spirits elevated their risk to the same level as those who had a family history of colon cancer. While alcohol in general has long been known to have a detrimental effect on the colon in particular, this study found that the alcohol in red wine did not.
Despite what is quickly becoming insurmountable evidence, skeptics continue to raise questions about whether there were other health habits of wine-drinkers that could be responsible for such results. Some argue that those who drink red wine are less likely to be smokers than those who drink white. Maybe red wine drinkers exercise more, or eat more green vegetables. How could it ever be justifiable to conclude that something like wine, which carries the potential for abuse, could be healthful? As much as it may go against the grain, there is no longer reason to deny that two types of polyphenols: resveratrol, and flavonoids, play key roles in red wine鈥檚 beneficial track record.
