i disagree. the interesting points aren't about food -- for example, it's a case study in how a lot of smart people, over a long period of time, can fool themselves -- in fact, the movements to improve software engineering have the same kind of faddishness as nutritionism.
another interesting point was how being "scientific", and looking at individual factors in isolation (e.g. vitamins) missed the forest for the trees, and did more harm than good.
another takeaway was the extent to which "studies" are pushed around/mediated by big political interests, e.g. the meat lobby and the marketing muscle (the suns, microsofts, and Extreme Programming vendors of the food world) that have a big interest in keeping the status quo.
