beer good A man walks into a bar and orders a 12-ounce bottle of Corona Extra. Another man walks in and orders a 12-ounce Guinness draft. The two men turn to each other, raise their glasses and say, "Here's to your health." Question: Whose dietary and health interests are better served by the 12-ounce beer? If the guidelines are less alcohol, fewer calories, fewer carbohydrates and, to top it off, protection against heart attacks, blindness and maybe even impotence, then it's the Guinness drinker, hands-down. No joke. Guinness, in fact, is lower in alcohol, calories and carbohydrates than Samuel Adams, Budweiser, Heineken and almost every other major-brand beer not classified as light or low-carb. It has fewer calories and carbohydrates than low-fat milk and orange juice, too. Could this be the same Irish stout that looks like a still-life root-beer float and tastes about as filling as a quarter-pounder with cheese?
