An article in Discover Magazine, Feb 98, page 44, mentions a study of high rates of PD and Lou Gehrig's disease in Guam and New Guinea. The researcher attributes this to calcium deficiency which leads to abnormal absorption of aluminum which causes neuron damage in the brain. Has anyone heard of aluminum as a causative agent in PD? Does aluminum occur naturally in foods or does it come from the preparation and storage of foods in aluminum? Ken Rowland [log in to unmask] http://FreeWeb.pdq.net/kenrow/index.htm
