Basically, the reason why cows and other ruminants are able to digest cellulose found in the grass is because of the contained microbes that are responsible for the production of necessary enzymes. The human stomach lacks these enzymes but, instead, contains others designed to digest other types of carbs, including simple sugars and starch.
How do cows digest grass?
The mouth is where the process begins. When the cattle swallows the plant material and saliva mix, it will travel down the esophagus to the rumen. Generally, the stomach functions to further break down plant matter and grain. A couple extra things to keep in mind are cecum, small intestine, and large intestine.

They only chew their food for a little before it is swallowed.
How do cows eat grass?
Let’s explore how cows are able to eat grass. The key to this ability lies in the stomach. After we chew and swallow our food, the stomach serves as a holding tank where digestion begins and food starts being separated into individual nutrients.
How do cows regurgitate grass?
Here, the grass is turned into cuds, which are basically chunks. Following the forming of cuds, the animal will start its regurgitation process. The chunks previously formed in the second chamber of the stomach are pushed back to the mouth so the cow can chew on them a bit more and break them down piece by piece.
How do humans digest grasses?
So as a matter of fact, the main players in grass digestion of the ruminants are the microbes that produce enzymes needed to break down cellulose. Humans just don’t have them. Well, humans do have the enzymes to digest other carbohydrates, like starch and simple sugars.
