The content of resveratrol in red wine might be a reason to drink a glass every day. Resveratrol significantly extends the lifespan of yeast and has been reported to prevent cancer and contain antiviral properties. Highly concentrated in the skin of red grapes, resveratrol has also shown to be beneficial against stroke, high cholesterol and heart disease - in mice. This is great news if you have pet mice who drink red wine.
It wouldn't take much to convince me to drink a glass of red wine each day and I have been doing it for a while. For other cheap bastards, like myself, I suggest Franzia wine in a box (5 liters).
