We all know the importance of eating healthy, but not everyone knows that the cookware you use to prepare your dishes is just as important as the food itself. Even the healthiest diet can result in severe health problems if your pots and pans are toxic. Find out which cookware you should avoid by all means for the sake of your own health and the health of your family. 

The non-stick properties of Teflon cookware are achieved with a coating of PTFE. This is a plastic polymer that, when heated above 572°F, starts to release toxins. These toxic fumes lead to flu-like symptoms called polymer fume fever, informally known as Teflon flu. Another chemical compound found in Teflon cookware is especially threatening since it tends to stay in the body (as well as in the environment) for long periods of time. Try cast-iron cookware instead. It even comes in non-stick varieties. It doesn't leak anything toxic into your food and is actually a nice natural way to increase your body’s iron levels.

Though aluminum cookware is usually coated, the coating is prone to chipping, allowing the toxic metal to get right into your food. As for aluminum foil, using it while cooking is even more dangerous. In fact, there’s an established safe amount of aluminum the human body can manage daily, and that’s 20 mg per pound of body weight a day. When you wrap your food in aluminum foil and cook it this way, the amount of this substance that leaks into the food significantly exceeds the permissible level. Consider using glass cookware instead. 

If you’ve just enjoyed some fish in lemon juice or stewed tomatoes cooked in an uncoated copper pot and you find yourself suffering from extremely unpleasant symptoms (such as vomiting blood, light-headedness, yellowy skin, or gastrointestinal distress, among others) call 911 immediately. Try this safe alternative instead: stainless steel. Just make sure you're buying food-grade stainless steel since this is the only type that doesn't contain any nickel or chromium.

Soft ceramic coating isn't durable enough and starts chipping after a few months of daily use. When this happens, lead and cadmium sometimes found in the coating will end up in your food and, thus, in your body. Lead poisoning is one of the most dangerous types of metal poisoning and can result in abdominal pain, headaches, infertility, and other health complications. Try this safe alternative instead: 100% ceramic cookware.
