Bowel habits are an excellent indicator of a person's digestive history — the foods we eat affect the color of our stool. However, they can also indicate infection, digestive problems, or, in rare instances, serious illness. Medical professionals consider stools that are any shade of brown to be healthy. Green stools may also be normal, depending upon a person's diet. By understanding what the different stool colors mean and why they occur, you can evaluate changes and determine whether medical intervention is necessary.

1. Chlorophyll Leads to Green Stools

Doctors consider a green stool to be healthy in most cases. Eating green leafy vegetables such as spinach, kale, Chinese cabbage, arugula, green beans, bok choy, and other greens can produce various shades of green stool. The chlorophyll in these plants is responsible for this characteristic. Drinking beverages made from flavored drink mixes that contain green food coloring or eating foods that contain green food dyes can also turn stools from a brownish color to vivid green. Consuming blue or purple foods such as blueberries can result in a greenish-blue stool, too.
