Luigi’s post on The glut of bugs in your gut opened a window here on a neglected aspect of biodiversity: the bacteria associated with certain foods and those associated with digesting that food. In all the background murmuring about probiotics and prebiotics, I’ve been hearing a lot of good sense from Seth Roberts. He’s the self-experimenter who devised the Shangri-La Diet (which isn’t a diet but a way of regulating appetite) and of late he’s been blogging more and more about fermented foods.
The things Roberts has noted are plentiful and diverse — I won’t summarize them here — but I can say that I’ve yet to meet a fermented food, in the widest sense, that I didn’t like. I also like playing with a few ferments myself. Of course there are fermentation fanatics, not just for the process as a whole but for particular “miracle mushrooms” and the like. ((To which, naturally, I have no intention of linking.)) And that puts some peoples’ backs up. But there is also probably a lot of good sense in making use not only of a diversity of ingredients, but also in a diversity of ways of processing them, outside and inside the body.
