The New York Times writes in a lead feature in its Sunday Magazine:
The story of how the most basic questions about what to eat ever got so complicated reveals a great deal about the institutional imperatives of the food industry, nutritional science and ahem journalism, three parties that stand to gain much from widespread confusion surrounding what is, after all, the most elemental question an omnivore confronts. Humans deciding what to eat without expert help something they have been doing with notable success since coming down out of the trees is seriously unprofitable if youre a food company, distinctly risky if youre a nutritionist and just plain boring if youre a newspaper editor or journalist. (Or, for that matter, an eater. Who wants to hear, yet again, Eat more fruits and vegetables?) And so, like a large gray fog, a great Conspiracy of Confusion has gathered around the simplest questions of nutrition much to the advantage of everybody involved. Except perhaps the ostensible beneficiary of all this nutritional expertise and advice: us, and our health and happiness as eaters.
