When you eat a lot of leafy greens like spinach, kale, and lettuce, your body breaks down the cellulose that makes up these plants and converts it into energy. As well as the plant waste products that come with this process cause a certain type of poop to appear which is green in color.

Green poop is not necessarily the result of eating too many vegetables. It can also be caused by other factors such as a bad diet or taking different supplements.

Also, poop is green when it is a result of the breakdown of chlorophyll and there are huge amounts of bacteria in the poop. The green poop can be caused by any number on the list:

1. People with sensitive digestive systems who suffer from diarrhea and abdominal pain
2. Those with low stomach acidity
3. Those who have been fasting for an extended period of time
4. Those who have eaten too much chlorophyll in their diet
5. Those who eat foods that are high in iron or other pigments
