Shocking yet great stuff here: the USDA has just released a one-page guide to vegetarianism that makes no obvious blunders. The document is actually helpful stuff. Sure, this very same content could have been produced by the American Dietetic Association back in the 1980s, but for the USDA to release something pertaining to vegetarianism without resorting to lies, scare tactics, and bad science breaks new ground for the agency.
Update: Nice blog entry about this from vegan dietician Virginia Messina. Link.
