Red koolaid or red jello, beets, or tomato products can cause red stool mixed in with mucus or if you are talking fiber (soluble) it will cause it to resemble a gel like substance and that can mix with the red food that you are passing. I hope its nothing serious but I'm glad you are getting it checked out.
