Overall, stainless steel releases very low metal amounts compared to other cookware. It does not contain harmful coatings or chemicals that can peel off. Choosing high-quality stainless steel with a proper grade (like 18/10) reduces risks. Cleaning and care also keep the surface intact, lowering leaching chances.
Allergic Reactions And Sensitivities
Some people have allergies or sensitivities to metals in stainless steel. Nickel is the main allergen found in many stainless steel types. It can cause skin irritation or digestive issues in sensitive individuals. This happens when nickel leaches into food or touches the skin.
Common symptoms of nickel sensitivity include:
- Rashes or redness on the skin
- Itching or burning sensations
- Stomach upset or nausea
- Swelling or inflammation
People with known nickel allergies should be cautious. Using stainless steel labeled as “nickel-free” or low-nickel grades may help. Other options include cookware made from glass, ceramic, or cast iron.
Here is a simple guide to metal allergies related to cookware:
