US Dietary Guidelines and advertising: balanced?

Michael Pollan, author and contributor to the New York Times, has written an exceptional article on the modern dilemma of "healthy eating" titled Unhappy Meals (found at http://www.michaelpollan.com/article.php?id=87) .
He sums up the entire article in the first line: "Eat food. Not too much. Mostly plants." The development of food processing industries, supermarkets, advertising, "diet craves," vitamins/isolated nutrients, and journalism surrounding the modern food industry are addressed in a surprisingly smooth read. (Things like wars between food industries [meat or dairy] and U.S. dietary guidelines have established a fragile balance between health logic and company advertising)... It's really worth a glance, and an interesting tie-in to our class discussions on both obesity/nutrition and food industry advertising.
