|Causes & Health Information|
- Almost always due to food coloring or food additives.
- Stool color relates more to what is eaten than to any disease.
- In children with diarrhea, the gastrointestinal (GI) passage time is very rapid. Stools often come out the same color as the red fluid that went in. Examples are Kool-Aid or Jell-O.
- The only colors we worry about are red, black (not dark green) and white.
