Anthropologists investigating the diets of our paleolithic ancestors at sites in Europe now believe cattail flour was a regular component. I’ve actually tasted the stuff before! I was studying Native American food preparation in California, and cattails grow here, too. Anyway, the point is: folks who eat nothing but raw meat and berries in an attempt to mimic a typical paleolithic diet may be missing an important element, for authenticity’s sake and for nutrition.
