On numerous occasions Pollan refers to the work of Dr. T. Colin Campbell. Campbell is the author of countless articles, but also the author of a well known and very controversial book called The China Study. While Campbell’s book and lectures do ultimately support the mantra, “Eat food. Not too much. Mostly plants.” The science employed to make the claim is considerably different. Campbell also takes a much firmer position on animal products that has earned him an interesting reputation. In some ways, Dr. T. Colin Campbell represents the scientist that Pollan criticizes in the first section of his book. Campbell is the Jacob Gould Schurman Professor Emeritus of Nutritional Biochemistry at Cornell University. A read of his position and the controversy surrounding his position might be interesting to readers of In Defense of Food. Much of the controversy surrounding Campbell has come from the Weston A. Price Foundation. However, thoughts and opinions about his work can be found all over the internet.
