The over-consumption of acidifying foods causes IBD. An excessively acidified body is a stressed body that becomes inflamed and deteriorates at a rapid pace. Foods are determined to be acidifying/acid-forming or alkalizing/alkaline-forming on the basis of their metabolic end reaction in our body. That means after the nutrients from a food are utilized in the cells, the resulting waste fluid pH is either acidic or alkaline. The mineral composition of foods determines whether the food will be acidifying or alkalizing.
