Perlmutter, for those who don't know, is a famed Neurologist to the extremely wealthy....the Elite. They travel from all around the world to visit his clinic in Naples, Florida. The Grain Lobby and its hack expert Nutritionists are up in arms because Perlmutter's suggested diet advises reducing carbohydrates to 5% of your diet and you should be highly selective of those carbs....meaning no refined flour and sugar, and he suggests avoiding sweet fruit. Of course, imagine if this approach were adopted by the entire nation, or even the entire world? Grain producers have too much invested to allow this to get any traction, and so, the notion is dismissed and marginalized by a mainstream press. Here's a link to reviews and comments of his book at Good Reads.

Here's a link to an example of the assassination of his book and thesis by the Grain Lobby's expert hacks.

I know one of the arguments to this wheat debate in the past has been that it's Elitist to say people should eat or not eat this or that when they are starving on the margins, but to that, I would point to a quote from the article posted by WR (thanks again) in the Collapse Culture thread by Gordon at runesoup.com entitled The Unavoidable Politics Of The Post-Apocalypse.

The people who have all the money do not talk about it. It’s somehow impolite. Beneath them. And it’s a behaviour we ape. Which makes it a lot easier to steal from us when we don’t know we’re being stolen from.
And so it is with food.
Promoting dietary health among low income earners is somehow perceived as an attack. “Hey poor people, just eat more salad!” And phrased that way, it certainly is.
However, the notion that access to life-sustaining food is somehow elitist is an insidious form of double-think, an archonic reverse psychology. Because it’s the seats at McDonald’s that are being widened, not the seats in Lear Jets.
