For some reason, this actually tends to prevent sloughing too much of our flora, and keeps the fauna of bacteria happy and balanced. A couple of days without the stimulation of nutrients inside the gut tunnel can erode both the flora and fauna. Regular feedings can help prevent this. After making the gut work every day, we need the right amount of calories, protein and individual nutrients. If there is a malabsorption problem, you ll need extra rations of all these components.
All food becomes non-nutrient food regardless of it's nutritional merits.
Picture in your mind, oatmeal on a spoon. There it stays. It s cheaper and, as a powder, travels easily. It's not a bad idea to have something on hand for those unexpected diarrhea emergencies. The flavor s not too bad and it may be awesomely helpful.
