How to Choose Safe Cookware




Yum

June 17, 2016 by Andrea Fabry 4 Comments

Safe cookware is foundational to a healthy kitchen. But how do I know which types are truly safe?

Are you confused when it comes to safe cookware options? Wondering which options are truly safe?

How to Choose Safe Cookware

From Teflon to stainless steel to cast iron—the choices can be confusing. Here is a brief overview of the three basic categories of cookware.

Reactive Cookware

This type of cookware is the most hazardous. The compounds react with food and can allow harmful chemicals to leach into foods and therefore our bodies.

Aluminum

Aluminum conducts heat well but is highly reactive, particularly with acidic foods. Aluminum is toxic to humans, and while proponents of aluminum cookware contend that the aluminum molecules don’t get into the food, is it worth the risk? Aluminum foil is also best avoided for cooking purposes. Aluminum sandwiched inside stainless steel should be okay since there is no contact with the food. (Note: Anodized aluminum uses an oxidative process designed to keep the product from leaching into the food. However, leakage may occur.)

Teflon-coated

Nonstick chemicals are linked to birth defects, liver toxicity, cancer, and more. The maker of Teflon warns consumers to keep pet birds away from the kitchen when cooking because “cooking fumes, smoke and odors that have little or no effect on people can seriously sicken and even kill birds, often quite quickly.” Even the EPA admits that one of the chemicals, perfluorooctanoic acid (PFOA):

  • is very persistent in the environment
  • is found at very low levels both in the environment and in the blood of the general U.S. population
  • remains in people for a very long time
  • causes developmental and other adverse effects in laboratory animals

If nonstick cookware must be used, cook at a lower temperature and avoid cooking on high. One additional note: Microwave popcorn bags are commonly coated with nonstick chemicals and are best avoided.

Less Reactive Cookware

Stainless Steel

Stainless steel is durable, resists cracks, and is the least reactive of all metals. Good quality stainless steel is essential. Less expensive stainless steel cookware may contain nickel and cadmium, which leach into food. To test your stainless steel, combine one teaspoon baking soda with one cup water and bring to a boil, then taste the water. If a metallic taste is present, the cookware may not be suitable for your kitchen.

Most stainless steel pots will have a number on the base. Look for 18/8 or 18/10. (18 indicates the level of chromium; 8 or 10 is the amount of nickel.)

Cast Iron

Cast iron is durable, an excellent heat conductor, and naturally nonstick. It must be maintained properly to avoid undesirable leaching of iron into foods. Some suggest this metal is desirable, while others say it’s not. Either way, it is best to be diligent in cleaning and maintaining your cast iron. One of the best ways to clean your cast iron is with coarse salt. Add some water and scrub with a cleansing cloth or sponge. Rinse and season. See this article for more on the chemistry of cast iron seasoning.

Non-Reactive Cookware

Glass

Glass is quite safe but does not conduct heat well and does not adapt to dramatic temperature changes. Hot glass cookware should not come in contact with wet countertops, nor be placed in water while still hot. Options for glass cookware include CorningWare, Pyrex, and Visions cookware.

Himalayan Salt Block

Cooking on a salt block can be a bit tricky, but it’s worth the effort. You are cooking food on food, after all—and the flavors of your food are greatly enhanced! For more on cooking with a Himalayan salt block, see this article.

Enameled Cast Iron

Enameled cast-iron cookware has been used for more than a century, merging the excellent heat conductivity of cast iron with the safety of protective, chemical-free glazing (assuming the old-fashioned methods are used). Enameled cast iron can withstand high cooking temperatures, and the heat is evenly spread throughout the cooking surface. This cookware is quite cumbersome and more expensive, but it can last a lifetime! Options for enameled cast iron include:

Le Creuset

All of Le Creuset’s enameled cast iron products are made in France. Their bakeware is made in Thailand and their mugs in China. All are guaranteed to be free of lead and cadmium. Don’t hesitate to contact the company with any questions about the manufacturing process. For a fascinating look at the finishing process for enameled cast iron, see Le Creuset’s informative explanation page. Le Creuset is available online and at many culinary and home stores.

Staub

Staub is also made in France, is also highly reputable, and is slightly cheaper than Le Creuset. It can also be purchased online and at many culinary and home stores.


What about Baking?

When it comes to baking, aluminum and non-stick cookie sheets can react with foods and are best lined with natural parchment paper to avoid direct contact. Glass is always a safe option for baking, and porcelain is often used as well. The German company Villeroy & Boch makes top-of-the-line porcelain bakeware.

What about Ceramic?

Ceramic cookware involves the forming, firing, and glazing of clay mixtures. The term ceramic includes porcelain, stoneware, and earthenware. Ceramic coated cookware tends to have a base made from aluminum. Ceramic cookware options include Xtrema, Emile Henry, and some Le Creuset products. For more, see Ultimate Guide to Ceramic Cookware.

What about Thermolon?

GreenPan promotes a safe alternative to Teflon with a Thermolon coating. Thermolon consists of oxygen, carbon, aluminum, and titanium. An additional ingredient is either silicon, which is natural, or silicone, which is not. The company insists it is silicon. I remain skeptical about the safety of Thermolon, but would love to hear your thoughts.


Whether you cook a lot or a little, safe cookware can go a long way toward improved health and simpler living!

    What brands of stainless steel would you recommend I was looking at calaphon tri ply or Cuisinart multi clad. Do either pass the vinegar baking soda test ?
