ewing gum, says Lieberman. But once you start processing it mechanically, even just slicing it, the effects on chewing performance are dramatic.
The evolution of the ability to chew food into smaller particles gave mammals a big boost of extra energy because smaller particles have a higher surface area to volume ratio, allowing digestive enzymes to then break food down more efficiently, he adds. The time saved from chewing, which most mammals must spend almost all of their days doing, also free
