I just watched a documentary on bbc2 called the men who made us fat, it was all about the dealings in the 70s with the corn industry and nixon and how the sugar lobbyists silenced a report about sugar and ill-health in the 70s and also against the world health organization as late as 2004
It explained how, when a recommendation for less fat and sugar was changed by the lobbysists to just less fat, a plethora of low fat products were created filled with sugar and corn syrup marketed as healthy
The show touched on how sugar was the main problem but still maintained that low fat was beneficial but they did mention how fat did not make you fat and how low fat did not stop you getting fat
The conclusion was that something has gone wrong with dietary recommendation within society as the obesity crises continues to cripple our health care systems. It essentially blamed sugar, HFCS and the unscrupulous industries but unfortunately it didn't say that fat was not bad.
Does anyone think it will ever catch up completely? Will dietary recommendations eventually be forced to change as obesity continues to snowball? Will the food industry eventually lose its muscle?

Conventional wisdom is nearly always behind the curve, but the arc of history bends toward justice: even in our lifetimes, I expect we'll see real change in the food industry. It will be agonizingly slow for those of us looking forward, and almost certainly incomplete; but information is difficult to suppress in the information age, and the data is on our side.
I haven't yet watched this particular documentary, but this kind of stuff really frustrates me. They seem to have many of the pieces of the puzzle, as you point out, that sugar is bad, low fat doesn't work, processed food is bad, but then they're not able to put the pieces together, and you get to the end and they recommend whole grain, low fat. It's like the twilight zone.
Conventional wisdom might catch up to sugar versus fat, but I dont think conventional wisdom (as in -the majority if people trying to eat healthy without going out of their way to read books-conventional) will catch up with the evils of grains, i.e. gluten and gliadin. Like Mike T above, this is frustrating as hell for me, because it's very easy to conceptualize what sugar does to our metabolism, but linking leaky gut, gluten, andauto-immune disease in one sentence for most folks is a little harder. Eh,.. we plot on... :) Edit: and to add to this--lobyists for General Mills, and the like, our dear leaders inthe government with their foodpyramids, etc. will not help to offset the situation.
I think conventional wisdom will jump on the bandwagon, but only because of the growing popularity of the diet and for financial gain of the various lobbies. We've seen this the past few years with "whole grains" and "organic." Now you see commercials for sugary cereals promoting "whole grains," and big biz companies like Heinz have organic products, etc., and you also see more and more gluten free products on the shelves and gluten free offerings in restaurants. I keep reading more mainstream articles about how high carb is bad, you should limit breads, pastas, etc., so I think ultimately there will be a shift and a paleo type diet will be touted as healthy, probably not as strict as full on paleo but I think it's getting to be on a more mainstream radar. I guess it's a good thing, but I also think it'll get mutated as all these things do and people who aren't really knowledgeable about it will abuse it, like eating 6 McDonald's burgers w/o the bun, etc...kind of the way it's gone with soy...when soy was touted as the next miracle food and then in showed up in everything and people were eating it with abandon in all its wrong forms (not that there really is a right form), TVP, soy milk, etc, because they think it's healthy....
