What can cause malabsorption? Many things, including an over abundance of an antagonistic mineral... when we become mineral deficient in one or more minerals, especially the macro minerals, we become more susceptible to pollutants including heavy metals as the body will use these to function as best it can in place of the minerals it craves. They also interfere with the absorption and utilization of the very minerals needed to correct the problem.
That is interesting. At the Chicago Health Expo, I asked four different people why my body wasn't absorbing enough minerals and I got four different answers. The answer that made the most sense to my was that the minerals bind to the toxins and the body gets rid of the new molecules. Another possibility would be a compromised digestive system. Another answer was you must constantly take minerals in because your mineral content changes from day to day.
