Why is My Poop Green?

6. Red Stools, Cranberries, and Red Food Coloring

When most people see red in their stools, they immediately associate the color with blood. In most cases, there is little cause for concern. A variety of foods lead to red-hued stools. Tomato soup, tomato or red vegetable juice, cranberries, beets, red peppers, and paprika can cause the color change. Red dyes are a common additive to processed foods and can also lead to red stools if a person ingests them. Red gelatin, red candies, cereals, and even snacks like Fire Cheetos can change the stool to a red color.
