We humans simply are not adapted to eat grass. Humans are not grazing animals, nor do we look or behave like grazing animals such as horses, cattle, bison, deer or antelope are. Physiologically speaking, Grasses themselves are too coarse of plant material for a human to digest. Cellulose, hemi-cellulose, fibre and lignin are structural components of a plant cell that is much more difficult to break down in the digestive system of a monogastric than it is for a ruminant. Thus, the grass leaves would simply pass through the monogastric's digestive system and be of no further nutritional value to that animal (being the human). It's a different story for the ruminant, though. See the related questions below for more.
