2. Foods that contain nickel
For years, nickel has been linked to eczema, with many sufferers being told to avoid wearing clothing or jewelry that contains this chemical element. However, nickel isn’t just something you wear or touch, it is in many of the foods we eat.
Foods like, cocoa, chocolate, soy beans, oatmeal, nuts, almonds and fresh and dried legumes. Even canned food that doesn’t already contain nickel can be dangerous simply due to being packed in a metal can.
