So I just spent the weekend acquiring yet another certification. A nutritional specialist, not a dietician not a nutritionist. A food coach is a better term, I can prescribe programs, evaluate, and recommend under the guise of licensed nutritionist or dietician.
Anyway one of the many things we talked about is what influences the guidelines in which we are supposed to follow. ie money and lobbyist.
Coincidently this article from the times really details the influences we need to be aware of as we make our nutritional choices.
