Basically all vegetables
No shit list is complete without vegetables, but since there are so many, we’ll just stick to a few honorable mentions. Spinach is high in both fiber and magnesium, both of which help the colon flush things through, and have been shown to relieve constipation. Broccoli is a superstar in the fiber world, and should be eaten raw for maximum digestive benefits. Again, most vegetables have some digestive benefits, so don’t force-feed yourself spinach and broccoli if they make you want to puke. Pooping is better.
