Canned food against a black background.
Why Heating Up Canned Food On The Stove Actually Isn't A Genius Hack
By Stacie Adams
Cooking canned items in their cans on the stovetop can have a negative impact on your health, while also increasing the chance of other hazards.
When direct heat is applied to cans, it can lead to the release of chromium, which may cause skin rash and shortness of breath.
Nickel exposure, which can also occur when applying direct heat to canned foods, is equally problematic thanks to its effects on internal organs, like the lungs and kidneys.
Placing a can on a stovetop can also cause it to explode, as the food inside will expand quickly. Thankfully, prepping canned food is convenient, so shortcuts aren't necessary.
