Does anyone suffering from IBD on this thread also have a nickel allergy? That is, are you sensitive to wearing jewelry, etc? I'm interested in whether or not there is a correlation to nickel allergies and IBD and whether or not medical studies have been done. Most people have stainless steel cookware, usually 18/10 (10% nickel) and cooking in these pots causes nickel to leech out, especially acidic foods for long periods of time. Interested in your feedback.
