I just read an article that I believe provides a compelling explanation as to how we’re getting ever closer to a complete rejection of the traditional food pyramid. That will be in spite of (rather than as a result of) the majority of “experts” in nutrition.  Check out the article here http://voiceandexit.com/networks-bring-experts-paleo-example/.  Here’s an extract:

“It wasn’t that Atkins, De Vany, Taubes, Sisson, Gedgaudas, Durant and Asprey were all trained nutrition experts — at least not the kind we normally think of. Nor had they commissioned expensive studies. [But] each of these figures had had a lot of good reasons to abandon the experts: Some were trying to help family members; Others thought the nutrition orthodoxy went against evolutionary biology; Still others just saw a nation of millions were getting fatter despite both expert nostra and fad diets. Then, they started talking to each other. They were influencers–force-multipliers. You might think of them as comms hubs or bigger nodes in a network. And they couldn’t have done it alone. The network had been millions of other amateurs willing to give these lifestyle changes a try. Most in this army of experimenters got incredible results and shared their experiences with others in the network. What followed was a wisdom-of-crowds phenomenon. Millions of people were not only seeing positive results, but starting to check the expert orthodoxy. …

It’s true that to some degree we have to rely on experts. It’s a perfectly natural part of specialization and division of labor that some people will know more about some things than you and that you are likely to need their help at some point. I am probably not very good at brain surgery either, so I might want to consult a neurosurgeon if I end up with a tumor in my head.

But when you get an army of networked people — sometimes amateurs — thinking, talking, tinkering and toying with ideas — you can hasten the proverbial paradigm shift. And this is exactly what we’ve seen with practitioners of the paleo and epi-paleo communities with respect to so-called nutrition expertise.

The problem of expert opinion is that it can very often be cloistered and restrictive. When science starts to seem like a walled system built around a small group of elites (many of whom are only sharing ideas with each other) — hubris and groupthink can take hold. No amount of education can catch up with an expansive network of people who have a greater stake in finding the truth than shoring up the walls of the guild.”
