There are no known human enzymes or cofactors dependent on Ni for normal function ( 4). Though Ni is known to be essential to the health of some species, it has not been proven to be essential to the health of humans ( 3). Nickel is a trace metal that occurs naturally in soils, water, plants, and animals. Both metals present many diverse potential sources. Nickel and to a less extent chromium are considered a frequent cause of ACD. Over the last several decades the prevalence of allergic contact dermatitis (ACD) has significantly increased ( 1, 2). Stainless steel cookware can be an overlooked source of nickel and chromium, where the contribution is dependent on stainless steel grade, cooking time, and cookware usage. The tenth cooking cycle, resulted in an average of 88 μg of Ni and 86 μg of Cr leached per 126 g serving of tomato sauce. Metal leaching decreases with sequential cooking cycles and stabilized after the sixth cooking cycle, though significant metal contributions to foods were still observed. Cooking with new stainless steel resulted in the largest increases. Longer cooking durations resulted in additional increases in metal leaching, where Ni concentrations increased 34 fold and Cr increased approximately 35 fold from sauces cooked without stainless steel. After six hours of cooking, Ni and Cr concentrations in tomato sauce increased up to 26- and 7-fold respectively, depending on the grade of stainless steel. After a simulated cooking process, samples were analyzed by ICP-MS for Ni and Cr. Trials included three types of stainless steels and a stainless steel saucepan cooking times of 2 to 20 hours, ten consecutive cooking cycles, and four commercial tomato sauces. This study examined stainless steel grades, cooking time, repetitive cooking cycles, and multiple types of tomato sauces for their effects on nickel and chromium leaching. Additional dietary sources, such as leaching from stainless steel cookware during food preparation, are not well characterized. Already acquired a gorgeous stainless steel cookware collection?
