Red wine

People who consume moderate amounts of red wine (and other types of alcohol, too) may be at reduced risk for heart disease, Alzheimer's, certain types of cancers, and even weight gain. The key word: moderation. A 5 ounce serving is about 130 calories.

Get it guilt free: Beware fishbowl-sized glasses, which make you more likely to overpour. Pour your wine into a measuring cup, and then dump it into your glass to see what a serving looks like in your glassware.
