There is absolutely nothing stopping you from eating grass.

More than 400 types of grasses can be eaten worldwide. Grasses are known for being edible and healthy eating because of their proteins and chlorophyll. Magnesium, phosphorus, iron, calcium, potassium, and zinc are commonly found in grasses. Grasses show up in your every-day foods, too.
