Tag: Chewing grass

According to research published in the *Proceedings of the National Academy of Sciences*, our early human ancestors did consume grasses around 3.5 million years ago, but modern human physiology has evolved beyond it. The central question for many today remains: Is it okay to chew on grass?

While grass is technically non-toxic and edible, humans cannot efficiently digest it due to the high cellulose content, rendering it mostly without nutritional value. This fundamental physiological difference, combined with several other health concerns, makes chewing on grass an ill-advised habit for humans.
