which kadai is best for health - #25090

I am really confused about something. Been doing a lot of cooking lately, trying to eat healthier since I feel like my diet could use a serious upgrade. I read somewhere that the type of cookware we use can affect our health, especially when it comes to cooking, and I just can't stop wondering which kadai is best for health. My mom always said when cooking with iron helps too, like maybe it adds some nutrients or something? But then I hear that certain non-stick ones can leach chemicals, which freaks me out a bit. I've been looking at options like stainless steel or even terracotta, but honestly, I have no clue which kadai is best for health. I'm worried I'm missing something crucial because I want to get this right! I make a lot of curries and stir-fries, right? If anyone has thoughts on which kadai might be healthiest or which materials to avoid for cooking, that would help a ton! Thanks in advance!
