Why did my poop smell today?

Anonymous
My poop doesn't smell when I eat regular food at the school cafeteria, or at a regular restaurant like thai express, A&W, McDonalds or Burger King.

Today my poop smelled - and this doesn't happen to me unless I eat food at an ethnic restaurant where the food might not be as chemically pure as a Tim Hortons or Wendys but I ate at home yesterday! What do you think happened?
