"Essentially, the idea is that we're part of the food chain, and in the food chain creatures eat other creatures, and so you can't just say, "This is beef." It's a very different food depending on what that cow or steer ate. A steer that was finished on grass is a completely different food than one that was finished on corn and industrial by-products in a feed lot. We don't pay enough attention to that. If you're eating from a grass-based food chain, you're getting a very different diet than if you're getting a corn-based diet."You should read the book. It's out. If you're not convinced by this simple piece of insight, then read some more from the article it came from.
