We have been struggling with a little constipation in our house. I found this idea at GAPSters
Beets! Yes, fresh, cooked beets have a mild laxative effect.
Here's what to do: cut the leaves off the beetroot about an inch above the crown. Immerse the beets in a pot of water. Cover. Bring water to a boil, turn down to simmer. Simmer for about 40 minutes, or until tender. Drain, rinse in cold water. With cold water running, hold beet under water and slip off the skins. Place beet in a clean bowl. Eat warm or cold.
