Thank you for your comment. While past research did find an association between aluminium and Alzheimer's, the association doesn't seem to stand to this day. (https://www.alz.org/alzheimers-dementia/what-is-alzheimers/myths).

Rather, cadmium, lead and manganese seem to be the prime heavy metal suspects of Alzheimer's now. But I didn't read into this topic in-depth, so I could be wrong about this. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7454042/#:~:text=In%20cell%20and%20animal%20model,cognitive%20function%20and%20cognitive%20decline.)

But you raise a good point in that we can't control everything. The best we can do is to make informed decisions.
