What this means for you

A Detox Score of 61 places aluminum foil (cooking) in the Low band. None of the three drivers is severe, which keeps the burden manageable. Small amounts of aluminum migrate into food, more so with heat and acidic ingredients like tomato or lemon. Everyday amounts are generally considered low-risk, but you can avoid the transfer entirely with an inert surface.
