5. Protects your teeth: Drinking wine protects your teeth from bacteria, thanks to wine's antimicrobial effects. In fact, scientists discovered degradation of bacteria after applying red wine to dental plaque.
6. Reduces the risk of certain types of cancer: Red grapes have been found to suppress the activity of aromatase - an enzyme used by breast tumors to produce their own estrogen, called an aromatase inhibitor. Red wine may also serve as a nutritional aromatase inhibitor, alleviating the elevated breast cancer risk, associated with alcohol intake. Of course, red grapes (particularly their seeds) are especially helpful.
Furthermore, resveratrol is thought to kill cancer cells by cutting off a pathway that feeds the cancer. The consumption of red wine has also been shown to reduce the risk of colon cancer by 50%. Harvard Men's Health Watch has reported that men who drink an average of four to seven glasses of red wine each week have a 52% less chance of being diagnosed with prostate cancer, when compared to those who don't. Doctors speculate that the flavanoids and resveratrol found in wine contain potent antioxidants that may counterbalance androgens - male hormones that stimulate the prostate.
7. Reduces your risk of diabetes : Once again, the resveratrol plays an important role here. Men and women who drink wine moderately have been shown to have a 30% lower risk of developing Type 2 diabetes. Possibly because the resveratrol improves sensitivity to insulin (and insulin resistance is believed to be the most important factor that contributes to Type 2 diabetes risk).
8. Fend off a cold: Here's a remedy your grandma must have used. Although it may have been speculation then, science can now back this age-old theory up. A study, conducted across 5 universities in Spain looked at 4,000 faculty members. In the study, it was found that those who drank wine were less likely to come down with a cold, in comparison to those who drank beer or spirits. Researchers believe that the antioxidants help lower inflammation and reduce the symptoms of a cold.
Bottom line: All these health benefits may very well tempt you to keep a bottle of red on your nightstand - however, not so fast. Doctors are generally wary in recommending people to start drinking wine, as of course, too much alcohol can have harmful effects on the body. And although resveratrol is a key component in red wine, there are potentially healthier ways of reaping its benefits. Alternatively, you may snack on blueberries, grapes and strawberries - all of which are natural sources of resveratrol.
