Eating a raw food diet is a recipe for disaster if you’re trying to boost your species’ brainpower. That’s because humans would have to spend more than 9 hours a day eating to get enough energy from unprocessed raw food alone to support our large brains, according to a new study that calculates the energetic costs of growing a bigger brain or body in primates.
“If you eat only raw food, there are not enough hours in the day to get enough calories to build such a large brain,” says Suzana Herculano-Houzel, a neuroscientist at the Federal University of Rio de Janeiro in Brazil who is co-author of the report. “We can afford more neurons, thanks to cooking.”
Paleoanthropologist Robert Martin of The Field Museum in Chicago, Illinois, agrees that the new paper does “provide the first evidence that metabolic limitations” from a raw food diet impose a limit on how big a primate’s brain—or body—can grow. “This could account for small brain sizes of great apes despite their large body sizes.”
A HUGE step forward in our civilization was the ability to cook food. This also lends credence to that as being the turning point of humans towards conquering the world. We just can’t sustain ourselves without it. So, while raw food is good, cooked food is a necessity and you are starving your brain without it.
