I am a HUGE prune fan. They are the #1 most nutritious food that you can eat. Surprised? I was.
Plus, they are amazing when it comes to regularity. I believe that if your metabolism is operating efficiently, you should be “going” frequently throughout the day. If you aren’t, then I would start by adding more prunes to your diet.
Just make sure they are not dried prunes as they are very caloric.
