Unfortunately it's behind a pay wall, but Kyrozis et al. report [1]:

" incident PD exhibited strong positive association with consumption of milk, but not cheese or yoghurt. This finding may help narrow down the search for potential dairy product components with a facilitatory role in PD. Concerning other dietary components, inverse association was found between polyunsaturated fat intake and incident PD. Also, inverse association was found with tobacco smoking, in line with previous studies, but not with caffeine."

I find the distinction between milk and yogurt and cheese interesting. Greek yoghurt is drained of most of the whey. Does this leave a lower fraction of any of the milk's aluminium content remaining in the curds?
