An average glass of wine, white or red, has fewer calories than your average light beer, and, obviously, it's classier, too. It's a no-brainer that the drier the wine, the less sugar it contains. That's good news for your burgeoning six-pack. If you can't decide whether to go for a glass of white or red, don't forget that red wine contains reservatrol, a chemical which is said to promote coronary health (in moderation, so stop guzzling that ish like it's grape juice, chief).
