Anyone can give nutrition advice.
A large fraction of the men and women who are given the status of nutrition experts in our society are actually nothing of the sort. Much of the dietary advice proffered by these poseurs is either repeated myth or made up completely. Bill Philips, author of the zillion-selling Body for Life, is a good example of a nutrition expert by reputation only. Among the pearls of wisdom dispensed in his book is the advice not to eat anything within an hour of completing a workout. I don’t know where Philips got this idea, but it is one of the gravest nutrition mistakes an athlete could make.
We have no one but ourselves to blame when we accept the likes of sitcom actress-turned-cottage industry of one Suzanne Somers, putative author of Suzanne Somers’ Get Skinny on Fabulous Food, as our nutrition oracles. But some of the fake nutrition experts are less easy to spot. For example, you might be surprised to learn that medical students typically get very little nutrition education in their four-year curriculum, yet they routinely give nutritional guidance to patients once they begin practicing. Because they did not get their knowledge of nutrition in their formal training, they get it all too often from the same place we do: the diet section of the bookstore.
