I'm wondering if you have an opinion on the safety of eating rice that has been cooked in a rice cooker that is made of aluminum? Our old rice cooker had a teflon coating that was starting to chip away so I thought it best to replace it and was excited to find one that didn't have a nonstick coating but after getting it home and using it I was informed that it's made of aluminum and how bad that is to cook with so now I'm wondering if I need to go shopping again. Any advice? Thanks
