It's a false dichotomy, of course. Using PubMed abstracts to search for the "optimal" diet is like searching for a needle in a haystack with a magnifying glass. That said, the other side of the coin is to use the Kitavans or the Inuit--populations that 99% of us know literally nothing about, except what we've read in our quest for dietary information--as "just so" stories. So we're left in the sandbox talking past each other.
When I taught middle and high school integrated science, I used Richard Feynman's quote to define science: "Science is the experiment." But where do experiments come from? What drives them? And this gets back to "science vs. anecdote." What drives science? I'd argue that it should be driven by observations. Patterns. Which lead to questions. Which lead to hypotheses. Then research. And, of course, research stimulates new questions and hypotheses and patterns. Recall that it was anecdotal evidence that led Jenner to create a vaccine for smallpox. A common observation about milkmaids that didn't get smallpox.
Today, we're left to fend for ourselves. Research is less purely knowledge-driven than it used to be, in my opinion. Agendas rule the day. Today's citizen scientist is an endangered species. Lavoisier, van Helmont, Benjamin Franklin--they would be labeled "Internet crackpots" in the contemporary milieu.
Personally, I wouldn't want anyone to extrapolate from my dietary experiments. I have celiac mutations on chromosome 6. Also, I carry an allele for cystic fibrosis. What other genetic aberrations do I carry that make it hard to generalize from what I know to be true in my own experience? What's best for me is quite possibly not best for the population at large. And, despite the fact that my dietary experiments have achieved outstanding results for me personally, I could very well be expressing a "live fast, die young" phenotype, characterized by early peaking, sexual mania, and early senescence.
So what brings me to this ramble? The safe starch debate, of course! Will you trust in PubMed articles about the glycation of dietary sugars to show you the way? Will you use the Kitavans or Inuit as your dietary model? Or will you attempt your own "new synthesis"? Or have you already found your own new synthesis in the writings and teachings of others?
