To evaluate toxic states of aluminum, the best testing we have is hair analysis, ideally used along with blood and urine analysis. The values can be followed during treatment by a doctor to see whether higher amounts are being eliminated and lesser amounts retained in body tissues.

Prevention: The best way to prevent aluminum buildup is to avoid the sources of aluminum. Eliminating foods that have aluminum additives is probably healthier overall. Not using common table salt is a positive health step as well. Some tap waters contain aluminum; this can be checked. Avoiding aluminum cookware and replacing it with stainless steel, ceramic, or glass is a good idea. Blocking skin and sweat pores with aluminum antiperspirants has always seemed strange to me; I would think it would be better to cleanse regularly, reduce stress, balance weight, and eat a wholesome diet that creates sweat that smells more like roses.
