It is important to monitor and understand which foods cause irritation as everyone can be different with what they can tolerate.
The main goal is to figure out what is disturbing your digestive system. If your previous diet was lacking high fiber foods (if you were juicing without the fiber) and you are now NutriBlasting (which includes the fiber), this could be a sign that you took it too fast...cut back on portions and introduce fiber slowly. Choose bland foods like banana, applesauce, rice and try some peppermint or chamomile tea to reduce inflammation and soothe your GI. Iron supplements help dry up loose stools.
Also, be sure to rehydrate. You lose a lot of water and electrolytes when diarrhea occurs. I'm not sure how this would taste, but how about banana, oats, apple, a dash of cinnamon, pumpkin seeds, and coconut water!
It may be important to provide low fiber foods during a flare up. Include foods like bananas, oats, peanut butter and coconut water as previously mentioned.
