Nutritionism

Nutritionism is an ideology that assumes that it is the scientifically identified nutrients in foods that determine their value in the diet. 

Originally credited to Gyorgy Scrinis, the notion was popularized in Michael Pollan's article "Unhappy Meals", published in The New York Times on January 28th, 2007. Pollan's stance was that humans have become disconnected from the natural food chain in such a way as to disrupt instincts relating to food intake, thus necessitating the reliance on nutritionism to make food choices. Because science has an incomplete understanding of how food affects the human body, Pollan argues, relying solely on nutritionism to make dietary decisions may be fallacious.
