> Aluminum cookware is very popular. Nonstick, scratch-resistant anodized aluminum cookware is a good choice. The hard surface is easy to clean. It is sealed so aluminum cannot get into food.
> There have been concerns in the past that aluminum cookware increases the risk for Alzheimer's disease. The Alzheimer's Association reports that using aluminum cookware is not a major risk for the disease.
> Uncoated aluminum cookware is a greater risk. This type of cookware can easily melt. It can cause burns if it gets too hot. Still, research has shown that the amount of aluminum this cookware leaches into food from is very small.
Not sure what "sealed" aluminum is nor what it would be coated with to prevent any kind of leaking. This is all new to me.
