I don't necessarily agree, it is only through the power of social media, 'the wisdom of crowds' that many people have come to understand how the diet / health hypothesis came about, how it was actually about the American economy rather than health, how Pharmaceutical industries are happy to keep us all sick, a patient cured is a customer lost. We are not all lucky enough to have forward thinking, up to date, research reading doctors like Dr Unwin or dieticians like Trudi Deakin. Despite the fact that they are winning awards for their innovative and successful interventions, it is not being rolled out across the NHS.
Many doctors do not question what they have been taught years ago at Medical School and most of their ongoing professional development is entirely sponsored by drug companies. My own doctor says he has to 'follow the guidelines' - but almost as an aside, "Keep doing what you are doing".
We are each, as individuals, responsible for decisions we make about our health and we are able to actually read the research and make informed decisions. I am glad that, some years ago, somebody pointed me in the direction of interesting and challenging reading as a result of which I have changed my diet and lifestyle and regained my health. Nobody is pretending to be a doctor, I certainly am not, but I do think it is the right thing to say, "Read, research, make your decision, it is your health".
