Although thought to be good source of protein, peanut butter is high in oxlate, a natural compound found in plant-based food. Excessive consumption of oxlate is known to cause pain in the joints, bowels and female genitals. Oxlate reacts with calcium to form oxlate crystals which can cause pain during urination and excretion. Peanuts are also a common food allergen and a discreet inflammatory food which may not show significant symptoms. On the other hand, the bread contains gluten and yeast whilst the complementing jelly contains sugar and preservatives.
