Can stainless steel pans leach nickel into acidic food?
Depends on the product. New, certified cookware is low risk. Old or imported ceramics may leach heavy metals.
What's actually in it
Heavy metals like nickel, chromium, lead, and cadmium can leach from cookware, ceramics, and food storage containers. Acidic foods speed up leaching.
Stainless steel can release nickel and chromium. Older or imported ceramics may contain lead in the glaze. Even "food-safe" products can leach trace amounts under repeated use and heat.
