Millions of aluminum pots are used everyday.... A couple of micrograms of aluminum in your diet, everyday, is not going to hurt you. Your body can presses and expel many milligrams of aluminum a day, through sweat and urine. Your body can process much more aluminum than you are going to get from cooking in a pan.

Regardless, the pots should last your whole life. If they are overly toxic (which they are not), they will still last your, possibly shortened, life.
