So the "hipster fad" is actually the eating of wheat. It's not a natural food for mankind to be consuming.
Well, mankind practiced almost universal cannibalism for around a million years [note: this is true]. Then after restricting cannibalism to certain tribes and certain occasions for around 10,000 years, we've only ceased cannibalism entirely during the last century. So the "hipster fad" is actually the lack of cannibalism. It's not a natural thing for mankind to not be consuming the brains of its vanquished enemies.
Wash, rinse, and repeat.
