Tag: Herbivores vs humans

According to research on ancient human diets, our ancestors once included grasses, but modern human physiology is fundamentally unsuited for consuming grass blades. So, is it safe for humans to eat grass? The scientific consensus points to significant health risks and minimal nutritional gain, making it an inadvisable food source for humans.

Biologically, humans lack the necessary digestive enzymes and systems to process the main component of grass, cellulose, for energy. Though we can consume it, our bodies cannot extract meaningful calories from it, unlike herbivores that have evolved specialized digestive tracts for this purpose.
