Tag: Lawn safety

Historically, early human ancestors did consume certain fibrous plant matter, but modern research confirms our digestive systems are not suited for common grass. While technically non-toxic, the high cellulose content and potential for contamination make the practice risky and nutritionally pointless, answering the question: is it safe to eat raw 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?

Unlike grazing animals with multiple stomachs, humans lack the necessary enzyme, cellulase, to break down cellulose, the tough fiber that makes up the bulk of grass. For this reason, consuming lawn grass will offer virtually no nutritional value and can cause significant digestive problems.

Humans cannot digest grass efficiently, unlike grazing animals. This is a key reason why consuming grass from your yard presents several health hazards.
