The first thing to understand about nutritionism is that it is not the same thing as nutrition. As the "-ism" suggests, it is not a scientific subject but an ideology. Ideologies are ways of organizing large swaths of life and experience under a set of shared but unexamined assumptions. This quality makes an ideology particularly hard to see, at least while it's still exerting its hold on your culture. A reigning ideology is a little like the weather--all pervasive and so virtually impossible to escape. Still, we can try. Michael Pollan, In Defense of Food: An Eater's Manifesto

 “That eating should be foremost about bodily health is a relatively new and, I think, destructive idea-destructive not just the pleasure of eating, which would be bad enough, but paradoxically of our health as well. Indeed, no people on earth worry more about the health consequences of their food choices than we Americans-and no people suffer from as many diet-related problems. We are becoming a nation of orthorexics: people with an unhealthy obsession with healthy eating.”

― Michael Pollan, In Defense of Food: An Eater's Manifesto

 

“But human deciding what to eat without professional guidance - something they have been doing with notable success since coming down out of the trees - is seriously unprofitable if you're a food company, a definite career loser if you're nutritionist, and just plain boring if you're a newspaper editor or reporter.”
― Michael Pollan, In Defense of Food: An Eater's Manifesto
