The latest advice on going paleo.

I’ve been doing this for about a year, though I haven’t gone whole hog (so to speak) on it. I still occasionally have a slice of bread, or potato, or legumes (though I’ve quit eating peanuts). And it’s tough to give up cheese.

The biggest problem with it is that most people in the world can’t afford it. Civilization happened because when agriculture happened, food became cheap, but not good for our health. If everyone started eating this way, prices of produce and meat would skyrocket — it’s just too inefficient, in terms of the acreage it takes to produce it, for everyone to be able to eat wild or range-fed meat and leaves. The ultimate solution may be genetic engineering that can produce healthy and good tasting foods in vats on a similar industrial scale to that of present-day refined grains. Of course, for many, the instant gratification of stuff that tastes good (sugar, bread, pasta), particularly when it’s cheap, will always overwhelm the long-term benefits of a better diet. But I think that the science is speaking very clearly on this issue now, and it’s time to end the war on fat and the nonsense of the FDA pyramid.
