With all the eloquence and presentational skill of a fifth-grade book report, Lee Fulkerson’s documentary makes a case for cutting animal products and processed food from your diet. If you’re curious about the whole-foods movement, try Michael Pollan’s book In Defense of Food, which addresses the subject from a wider variety of perspectives and does so in a far less insulting manner than this extended infomercial, with its muzak score, entire sequences lifted from network TV news, and bar graphs illustrating every other scene.
