Such is the case now when I watched the Daily Colbert tonight, where the guest was John Durant. He spoke about his new "caveman" diet/way-of-life that he thinks is our one true diet. We should be eating more meat, and no bread. People in paleolithic societies live to ripe old ages as long as they don't die in early childhood. All our diseases are due to our eating "modern" (read: 'processed') foods. And other such nuggets of folk wisdom.
Now you may think that the whole fAtkins diet rebranding gets my knickers in a twist because it's contrary to the vegan thing you heard I like. But that's only a small reason, if any. Mainly it's this whole nostalgia for the past that never was. The cartoon version of primitive humans taking a bite out of a mammoth simply isn't true. I think Wikipedia has a good summary. The concept is just a continuation of the whole natural-is-automatically-good-for-you mantra that just bugs the heck out of me (arsenic, uranium, strychnine, poliovirus, all natural! they must be good for you!)
Durant's main point seems to be that we should eat the diet we have evolved to eat. He just thinks that in the 10,000 years since the dawn of agriculture humans have not evolved.
This brings me to the original item I was going to post, that shows that we have evolved since then. It points to an event that changed our bodies more than agriculture has, that being that Promethean moment we started cooking. Primatologist Richard Wrangham has many interesting points in the podcast, and I plan on digging in to his book (pun intended) for more.
The point that stuck out for me, especially as someone who has done more polyacrylamide gel electrophoresis (PAGE) than is probably good for them. As anyone who has poured their own gels, or had to dispose of used gels knows (or perhaps, only those of the above who read the MSDS), the acrylamide monomer of the gel is described as a potent neurotoxin (atleast when tested on cats).
Yet our friend C3H5NO is found in starchy cooked foods that most of us eat every day. Those very same unnatural breads and pastas and baked potatoes that raw-foodists and paleo-dieters flee from. How can this be? Richard Wrangham and others (including your humble narrator) think this is one of many evolutionary adaptations that modern H. sapiens has gained since cooking and processing food.
And I find it especially funny (if morbidly) that much of the negative health indications derive from animal tests, as in the aforementioned one with the poor kitties. If we tested chocolate on dogs, we'd never be able to eat that either (and that's a processed food too). But if we tested all-natural raw strychnine in guinea pigs we'd be in for a shock when that product hit the shelves.
Im not saying we should all load up on deep-fried vegan twinkies, I just think we should eat healthy, and not eat something because it's natural. And of course, eat without killing animals. But you knew that.
