I have a mostly healthy diet with a day or two in the month where I eat junk, like popcorn and apple pie with ice cream
I recently started mixing Amazing Grass
Superfoods and Wheat grass
in my morning smoothies. My smoothies include a helping of berries: blue, black, and strawberries with banana and grape juice. Not sure if the superfoods have causes this grainy stool, but I am concerned since it lasts for a couple of days.
