Newsweek is reporting a major breakthrough in the world of vegetarianism. In short, veggie lovers have found their Holy Grail: guilt-free meat (and by meat, we're talking red meat--not fish or free-range chickens, which haven't been as meat in the minds of many vegetarians in years). Incredibly, hard-working food-ethic trendsetters have now made it not just possible but cool to eat beef without all that stomach-turning guilt. The key is "responsibly raised," grass-fed beef. Even more remarkable, according to the Newsweek article, is that the cachet attached this high-end red meat allows vegetarians to be as smug as ever about their food choices.
