I missed this last year, but it is worth noting that aluminum is not dangerous in the levels that would be absorbed from aluminum cookware or foil, or, for that matter, aluminum keys. It is by far the most common metal in the earth’s crust and you get exposed every time you touch dirt.
Brass, OTOH, often contains lead in addition to the copper and zinc that defines the alloy and there is no safe level of exposure to lead. Don’t cook anything brass with your food.
