Still storing leftovers in aluminum foil? Doctors warn this everyday kitchen habit could increase metal exposure; here's a list of foods to avoid

In many American households, people depend on aluminum foil and disposable aluminum containers to wrap leftovers, pack lunches, or keep meals warm. The reason is simple- they are cost-effective, convenient and easy to use. But experts have pointed out that the way you use aluminum foil may have a bigger impact on your health than you think.

While using aluminum foil occasionally is generally considered safe, storing certain foods in it for long periods or cooking directly with it at high temperatures may increase the amount of aluminum that ends up in your meal, according to a report in ETimes. Medical experts have urged people to pay closer attention to how they use aluminum foil, especially when storing acidic, salty, or spicy foods.
