Thank you!

And being versed in nutrition as a science seems like it could take a lifetime. But there is a Michael Pollan quote that's coming to me. Here he is discussing his reasons why he wrote (another) book, this time not on the ethics of our food chain but on personal nutritional decisions:

But many readers wanted to know, after they’d spent a few hundred pages following me following the food chains that feed us, “Okay, but what should I eat? And now that you’ve been to the feedlots, the food-processing plants, the organic factory farms, and the local farms and ranches, what do you eat?”

Fair questions, though it does seem to me a symptom of our present confusion about food that people would feel the need to consult a journalist, or for that matter a nutritionist or doctor or government food pyramid, on so basic a question about the conduct of our everyday lives as humans. I mean, what other animal needs professional help in deciding what it should eat? True, as omnivores—creatures that can eat just about anything nature has to offer and that in fact need to eat a wide variety of different things in order to be healthy—the "What to eat” question is somewhat more complicated for us than it is for, say, cows.Yet for most of human history, humans have navigated the question without expert advice.To guide us we had, instead, Culture, which, at least when it comes to food, is really just a fancy word for your mother. What to eat, how much of it to eat, what order in which to eat it, with what and when and with whom have for most of human history been a set of questions long settled and passed down from parents to children without a lot of controversy or fuss.
