Via Paul at Locussolus (and formerly of Too Many Chefs) - Mark Bittman makes the case at the amazing TED conference for a more plant-heavy, meat-light diet. This explains for me why he produced the (mostly) vegetarian version of his How to Cook Everything book.
While you're there, check out the rest of the talks at TED. It's a remarkable conference that brings together some of the most dynamic minds around in all fields.
Kelli, Bittman's Best Recipes Book left me completely cold. I didn't agree with a lot of his recipes - especially when they were being presented as the "best" versions.
But the Vegetarian How to Cook Everything and to some extent, the non-vegetarian one changed my mind about him. He's not the final word on food, (Harold McGee is still that), but he's someone whose opinion I now respect.
This guy Bittman is a Moron...may be a great chef, but a moron as to the real earth.
Ha! My boyfriend has that t-shirt (well, the bomb, not beef, version), and people all over NYC stare at his chest whenever he wears it. It really throws them for a loop. =)
More importantly, 'How to Cook Everything Vegetarian' is one of my very favorite cookbooks EVER. I thought I hated Bittman until I read it!
