Yesterday i ate fruit loops for breakfast and i had green peas with my dinner. today i had a bowel movement and it was part brown and part green.

Stool color: stool color can vary for many reasons, including particular foods eaten, disease states, and medications. A change in stool color in the course of one stool is not unusual, and would only be concerning if you saw red or solid black stool. These could be signs of internal bleeding. if you're not sure, see your doctor to check. Good luck.
