Is cooking with cast iron bad for you?
No, cooking with cast iron isn’t bad for you. In fact, cooking with cast iron has more health benefits than detriments.
Cast iron is naturally chemical-free, so no matter how long you use it or how much heat you use, you’ll never ingest dangerous chemicals due to your cookware.
Additionally, seasoned cast iron is non-stick, allowing you to use less oil and fat when you cook.
Lastly, because of its rich iron content, cast iron releases small amounts of iron into your food. While this may sound scary, it’s actually a health benefit, as many people suffer from iron deficiency. And the iron is released in such small amounts that people who are not iron-deficient won’t be affected.
