It's the ethanol or alcohol in beer, wine and liquor that researchers believe increases cancer risk.

"So while you're checking the bottle label, check the ethanol percentage or number as well," McKindley says. "You'll find either an alcohol by volume (ABV) percentage or an alcohol proof number."

ABV and alcohol proof are standard measures used worldwide to show how much alcohol or ethanol is in a beverage. In the United States, the alcohol proof number is twice the ABV percentage.

Beer, wine and liquor contain the same amount of alcohol per serving ” about half an ounce. That equals to about:

40% ABV or 80-proof in liquor 2 - 12% ABV in beer 9 - 18% ABV in wine

"Avoid anything with even more alcohol, like 100-proof liquor," McKindley says.

Non-alcoholic drinks are probably best

Avoiding alcohol, or limiting the amount you drink, is your best bet to ringing in a healthy New Year. If you're looking for a non-alcoholic drink with a "cocktail-like" feel, try club soda and lime. It has minimal calories and health risks.

"Remember, alcoholic beverages offer few nutritional benefits," McKindley says. "Look for healthier food sources and practice portion control during the holidays."
