Which type of tawa is best for health?

Can you explain to me which type of tawa, a traditional Indian cooking utensil, is considered the most beneficial for health? Is it the iron tawa that provides essential minerals through cooking, or perhaps the non-stick tawa that requires less oil and prevents sticking? Or is there another type that I'm not aware of that offers unique health benefits? I'm particularly interested in understanding the potential health impacts of each option and how they compare to each other.
