It’s incredibly unlikely that you’ll consume toxic amounts of aluminum just by cooking with foil.

“An average healthy person is at very minimal risk for aluminum toxicity, if any,” Wegman says. According to the Centers for Disease Control (CDC), “Most aluminum in food, water and medicines leaves your body quickly in the feces,” while “much of the small amount of aluminum that does enter the bloodstream will quickly leave your body in the urine.”

There’s been some debate over whether or not aluminum foil might contribute to the development of Alzheimer’s disease, but according to the Alzheimer’s Association, current research doesn’t show that aluminum foil poses any threat.

High temperatures and acidic foods can cause slightly more aluminum to leach into food.

While there really is no threat of consuming toxic levels of aluminum under ordinary circumstances, there are certain things you can do to minimize the amount of aluminum that leaches into your food from foil. “The recommendation is to avoid cooking things in or on aluminum foil at really high temperatures (400°F or above), and to avoid wrapping acidic foods in aluminum foil for long periods of time,” Wegman says.

Again, it’s highly unlikely that using aluminum foil at high temperatures or with acidic foods will cause any harm. But if you’re worried, you can use parchment paper instead of using aluminum foil for high-temperature cooking, and store acidic leftovers (anything that contains lots of citrus, vinegar or tomato) in glass containers instead of wrapped in foil.

Bottom line: There’s no need to worry about aluminum foil.

“I have never seen or heard of a case of aluminum toxicity,” Wegman says. Your body does a fine job of getting rid of any aluminum you eat, drink or breathe in.
