How cookware can affect your health

Using healthy ingredients doesn’t guarantee that your home-cooked meals are good for you—cookware needs to be a consideration, too. “Some surfaces can chip off and mix with food,” says executive chef Al Frey of Lehigh Valley Hospital and Health Network. “And some metals react with certain foods and affect the taste,” says his colleague, registered dietitian Elena Blanco.

Here’s what you should know when shopping for and using cookware:

Teflon

Pros This inexpensive, nonstick surface is easy to cook with and clean.
Cons Metal utensils cause Teflon to scratch and flake. Consumed flakes may contribute to certain cancers.
Tips Use rubber utensils. Clean Teflon by hand, not in a dishwasher, and throw away scratched cookware.

Cast Iron

Pros If you’re anemic (deficient in iron, which is vital to healthy blood), this cookware adds a little iron to everything you cook. Cast iron is durable and versatile.
Cons It’s heavy and doesn’t heat up quickly or evenly.
Tips “Seasoning” cast iron with oil or shortening prevents rust and creates a permanent nonstick surface. Use two hands to transport heavy pans.

Aluminum

Pros It’s durable and an excellent heat conductor, warming up quickly and evenly.
Cons Although it’s relatively harmless, aluminum reacts with the acid in some fruits and vegetables, causing an odd taste. This same reaction can cause aluminum pans to corrode.
Tips Teflon-coated aluminum eliminates the reaction.

Copper

Pros It heats and cools quickly, helpful when you’re preparing delicate sauces.
Cons Copper reacts with all ingredients, giving food a slight metallic taste.
Tips Get the benefits of copper without the drawbacks by using stainless steel cookware with a copper bottom.

Stainless Steel

Pros It’s durable, dishwasher-safe and attractive.
Cons It’s a poor heat conductor, and you need to use oil or fat to keep foods from sticking.
Tips Use a healthy fat like olive or canola oil. Choose stainless cookware with a copper or aluminum bottom layer for better heat conducting.
