Imagine a disaster hitting the area where you live, causing the food supply to halt temporarily. All grocery stores have been emptied and you’ve eaten everything in your pantry. What are you going to eat to survive? Well, the answer isn’t grass from your lawn.
There are two main problems with humans eating grass.
First, humans don’t get any energy from grass. Unlike many other animals, our digestive system is unable to break down the cellulose in grass properly. In fact, grass can have a negative calorie count in humans. This means you can actually lose energy as your digestive system tries to break down and digest the grass.
The second problem is the damage that grass will do to your teeth. Grass has a lot of silica in it. Silica is a strong abrasive that will quickly wear down your teeth. Grazing animals, such as cows, have adapted over time and continually grow and replace worn down tooth surfaces.
- Grasses have evolved to grow at their base instead of their tips in order to protect themselves, unlike most plants.
- There are over 10,000 types of grass species in the world.
- The fiber from many types of grass is used in the making of paper.
