It's well established that some trace amount of aluminum leaches into your food when using foil, and it's more pronounced with acidic foods. As far as I'm aware there's no evidence of any health effects of this (still trace) amount. The main hypothesis is aluminum may somehow be linked to Alzheimer's, and dietary aluminum may be the source of that. The Alzheimer's Association rather definitively says there is no known link and most current evidence doesn't support this: https://www.alzheimers.org.uk/about-dementia/risk-factors-and-prevention/metals-and-dementia https://www.alzheimers.org.uk/about-dementia/risk-factors-an... Every other health effect I've seen hypothesized seems even more fringe.
