If I suspected I were having problems with the nutritional yeast addition to my superfood I would leave it out and see how that goes. It seems to me that life is a bunch of little trials, as we become aware of different foods, ingredients, the need for exercise, the need for good water and on and on. Through these little trials we learn to make the changes we need for a healthier body. What works and what does not.
Just keep on going, study, then apply what we learn. Life is such a sweet blessing.
