Is stainless steel safer than silicone for cooking utensils?
Slightly. Stainless steel doesn't shed anything. Silicone leaches trace siloxanes.
What's actually in it
Good stainless steel (18/10) releases trace amounts of nickel and chromium, mostly into acidic foods during the first few uses. Silicone releases trace cyclic siloxanes, faster when heated. Both beat plastic, nonstick, or black recycled plastic.
For most cooks, the practical difference is small. Stainless has a slight edge for high-heat work; silicone is better for jobs where metal would scratch.
What the research says
A 2025 study in Int J Environ Health Res measured metal leaching from cooking surfaces and found quality stainless leached very little. A 2025 study quantified siloxane release from silicone.
Use stainless for high-heat work and silicone where you need flexibility. Avoid plastic and black recycled plastic entirely.
