Why Is My Poop Green?
2. Green Dyes
Changing the color of food is not a modern development. Spices like turmeric have long been used to help add some color to food to make them look (and smell) more appealing. We still do the same thing today, only todays dyes are more likely to be made from chemicals. If you have green candies and other junk foods, it is likely the green coloring would have come from an artificial coloring agent.
If you consume a lot of these then there is a chance they will not be completely broken down, causing your poop to take on a green color.
