With high stomach acid levels, we as humans can pretty much digest most organic materials and compounds, however at one point humans were able to digest grass and leaves and one point thousands of years ago. Evidence is found in our appendix a small useless organ that at one point secreted enzymes that helped digest leaves/grass, with evolution this organ wasn't necessary and slowly shrank giving no function to the body. People can live without the appendix.

Humans can digest starch because they produce an enzyme called amylase that can break down starch into simpler sugars. However, humans lack the enzyme needed to break down cellulose, which is a complex carbohydrate found in plant cell walls. This is why humans cannot digest cellulose.
