There have been two recent animal studies in Spain indicating that beer is capable of removing aluminum from brain cells, allowing the brain to heal from its toxicity and inflammation. The most recent study used non-alcoholic beer, and the earlier one used beer with alcohol. Both types of beer, mostly due to their antioxidant hops content and silica from silicic acid used in the brewing process, have been observed leaching aluminum from aluminum nitrate induced into lab rats. Aluminum that gets into brain tissue creates all sorts of neurological ills. Silica binds with aluminum to neutralize its toxicity and escort it out of the body through urine. Cucumbers and the herb horsetail are high in silica that doesn't penetrate the blood-brain barrier. Beer contains the silicic acid which does. But there is a serious caveat for using beer to eliminate aluminum from the brain that will be discussed in this article.
