Organophosphate and Mercury Contamination

Low level organophosphate or mercury contamination deactivates the DPP4 enzyme. This means that one should consume foods that are subject to low level of this contamination separately from foods that contain casein or gluten. Otherwise, the casein or gluten may not be properly digested. Casein can complex with catechins. So, when casein in not broken down, the catechins consumed with it may not be properly digested either. This is why some people, like me, prefer to eat wild Alaskan salmon in a separate meal from one one with milk and whole grain bread.
