Katie Couric's Notebook: Alcohol Moderation

There was a time in life when the only advice about alcohol you heeded was "beer before liquor, never sicker." But as you get older, you start paying attention to all those medical studies, and they are enough to make your head spin.

There's a new one, from Oxford University, that seems to contradict the notion that a glass of wine of day keeps the doctor away.

Researchers studied more than a million women and concluded that even moderate drinking can increase your risk of cancer.

These results come just weeks after another study determined resveratrol, a chemical found in red wine, can actually reduce cholesterol and is good for your heart.

So, which is it? Good for you, or bad?

It's important to stay informed, but in the end, you could do everything right and still not live to be a 100. Our destinies are sometimes determined by a genetic game of Russian roulette.

But the bottom line: Moderation. And make sensible choices.

I'll drink to that.
