Are aluminum cans safe for storing acidic drinks?
For most uses, aluminum cookware is low risk. Avoid cooking acidic foods in uncoated aluminum.
What's actually in it
Aluminum is the most abundant metal in the earth's crust and is naturally present in food and water. Aluminum cookware, foil, and cans are among the most common kitchen products.
Aluminum leaches into food more readily from acidic foods like tomatoes, vinegar-based sauces, and citrus. High temperatures increase leaching. The kidneys filter aluminum efficiently in healthy people, but high chronic intake has been linked to neurological effects.
