Aluminum from cookware leaches into food during cooking
Aluminum from cookware is known to leach into food during the cooking process, a risk that increases with acidity and cooking duration.
Papers [1] and [2] provide direct empirical evidence that aluminum leaches from cookware into food, especially under specific conditions like higher acidity and prolonged cooking times. The remaining papers are largely off-topic or address other metals and contaminants (such as PFAS or lead in spices), meaning the supportive evidence is robust and uncontradicted.

The study demonstrates that aluminum leaches from both anodized and non-anodized cookware into food during the cooking process, particularly under acidic conditions.

This review highlights that aluminum cookware releases metal into food during cooking, a process that is further facilitated by high temperatures and extended cooking times.
