Is it safe to use Aluminium tawa?

I've been wondering, is it really SAFE to use an aluminium tawa in my cooking? I've heard mixed reviews, with some people saying it's perfectly fine and others expressing concerns about potential health risks. Could you help clarify the situation for me? Is there any scientific evidence to support or refute the safety of aluminium tawas? And if they're not safe, what are some alternative options I could consider for my cooking needs? Thank you for your help.
