My mother-in-law has Alzheimer's and I have not heard that link being mentioned. It is in a lot of food products, but so are a lot of other things. The answer is that we do not know what causes Alzheimer's or ALS. My mother had ALS. Ask me which is worse and my answer is I am not sure. My mother was in pain, but her memory is intact. My mother-in-law is not in pain, but knows she is forgetting cherish memories.
