Is it safe to store tomato sauce in aluminum cans long-term?
For most uses, low risk. Avoid cooking acidic foods directly in uncoated aluminum.
What's actually in it
Aluminum cookware and foil are common kitchen staples. Aluminum leaches into food, especially acidic foods like tomatoes, citrus, and vinegar-based dishes.
Healthy kidneys filter aluminum efficiently. But high chronic intake and certain conditions can cause it to build up. The concern is more about regular, repeated exposure over years.
