How Safe Is Cast Iron Cookware? Truth and Myths 2023

Cast iron cookware has been a staple in kitchens for centuries. It is known for its durability, even heat distribution, and ability to retain heat. However, some people are concerned about the safety of using cast iron cookware for cooking. 

Is cast iron cookware safe for health?

Is there any health risk while cooking with cast iron cookware?

If you only ate cast iron, you’d have to be a mouse to reap the health benefits of the mineral consumption. Due to the microscopic size at which mineral transfer occurs, cast iron is not inherently healthier than other cooking surfaces. While it may help with the sting, it won’t help with the anemia.

Typically, people use seasoned cast-iron skillets, which do not release considerable amounts of iron into food. As a result, using cast iron in the kitchen should be seen as something other than a viable alternative to eating iron-rich foods.

 In this article, we will examine the safety of cast iron cookware and provide the information you need to make an informed decision while purchasing cast iron cookware.

Is Cast Iron Cookware Safe For Health? What Does The Research Say About It?

Previously, people thought that by using a cast iron skillet, their food would absorb a lot more iron if they ate it. Researchers evaluated twenty items to prove this, and the results were published in the Journal of the American Dietetic Association in July 1986, proving the claim. 

They measured iron and moisture content before and after cooking in an iron skillet and a non-iron dish. Because iron absorption might be impacted by how long it takes for a skillet to season, they used a brand-new, pre-seasoned cast-iron pan. The study also compared the effectiveness of a brand-new iron skillet to that of a slightly used one regarding iron absorption.

According to the study, many dishes’ iron levels dramatically increase when cooked in an iron pan. Applesauce and spaghetti sauce are two examples of high-acid, high-moisture foods that are great for iron absorption. The amount of iron in applesauce per 100 grams (approximately 3 oz) grew from 0.35 mg to 7.3 mg, whereas the amount of iron in spaghetti sauce went from 0.6 mg to 5.7 mg.

Iron absorption increased in food when cooked at lower temperatures for extended periods. In addition, they discovered that iron content in foods increased when cooked in a modern iron skillet compared to an older one. Because the iron was in constant touch with the food during the cooking process, the food absorbed more iron when the heat and stirring were applied more often. Iron absorption was reduced from hamburgers, corn tortillas, cornbread, and liver with onions. Most likely, this was because they were cooked for shorter periods and had less time to develop a crust because they were turned only once or not at all.

Iron absorption during home cooking has been linked to factors such as the skillet’s age and the heated dish’s length.

Is Cast Iron Skillet Proved To Be A Source Of Iron? 

A tiny amount of the mineral from the cast iron pan will be transferred to the meal and absorbed by the body as a result of cooking with cast iron. Due to the limited mineral transfer, it would be difficult to argue that cast-iron cookware is a significant source of iron.

What science has to say about it is as follows: 

An attempt in 2003 to evaluate whether or not cast iron meal preparation could help reduce anemia in underdeveloped countries failed to find convincing evidence in favor of the skillets. The authors discovered encouraging findings but cautioned that further research is needed before cast iron may be widely touted for its mineral transfer benefits in treating anemia. It means that while some people did experience an increase in hemoglobin production, this was not a consistent or predictable trend.

A component that can remove the iron from the pan using acid is also essential for iron transfer. By 2020, research out of Korea had established that acids were the trigger for mineral extraction from cast-iron cookware. Oiling cast iron, on the other hand, decreased acid-induced mineral leaching.

What does this imply, then? 

Iron, and any other minerals in the pan, won’t be drawn into food if you don’t use acidic ingredients (and ideally high heat). 

“The release of hazardous metals was significantly dependent on pH.” 

write the scientists. If you cook acidic foods, a cast iron pan’s coating can be “stripped” of its protective microlayers.

To What Extent Can Cast-Iron Skillets Improve Your Health?

We could benefit from more research on the viability of cast iron pans as a good iron supply, but we can still take measures right now to increase their use.

• Get plenty of use out of them

Cast iron increases your net iron intake the more you use it. One more benefit of using your pans frequently is that they will last longer and perform better with each usage.

• It would help if you weren’t Scared To Prepare Meals With High Acidity.

We are cautioned against using cast-iron cookware for foods with a high pH. To absorb the most iron possible, you should utilize acidic compounds (those with a lower pH) because of their mild surface-stripping properties.

• Put Them To Good Use By Cooking Iron-Rich Dishes 

Searing, sautéing, and roasting meals that already contain a lot of iron suit your skillet. While red meat and other animal proteins are excellent providers of iron, there are also many excellent vegetarian options. Iron-rich tofu, lentils, and chickpeas are simple to incorporate into a stir-fry.

What Are The Benefits And Side Effects Of Cast Iron Cookware?

Cast iron is the best material for making cookware since it is durable, heats evenly and quickly, is inexpensive, and does not stick. It’s impossible to use a cast-iron pot for every meal, it’s cumbersome to move around, and it needs regular maintenance (seasoning) to keep it in good cooking shape. Rust develops on cast iron if it isn’t maintained correctly. However, cast iron cookware has disadvantages, too, besides its advantages. Here I’ve listed some of them:

Benefits of Cooking With Cast Iron Cookware

• Intended for use in both conventional and convection ovens
• Superior resistance to extremely high temperatures
• Superior ability to retain heat
• Versatile
• Durable
• Nonstick (when seasoning maintained)
• Non-destructive to the iron’s finish when cleaned.
• Reliable stoves and pots 
• no dangerous coatings
• endless existence
• Affordable

Side Effects Of Cast Iron Cookware

• You may consume more iron from meals cooked in cast iron pans than you would from other sources. While fresher, unseasoned pans will leach more iron than older ones cooked with acidic foods, the reverse is true for well-seasoned, older pans.
• Cast iron is difficult to work with because of its weight and requires special attention (at least until it is thoroughly seasoned).
• Because cast iron isn’t a great heat conductor, it can easily create uneven temperatures in different areas.
• Tomato sauce cooked in a cast-iron skillet may take on an off-flavor due to the leached iron. Seasoned pans are your friend here for their nonstick properties and for preventing unwanted flavors from transferring to the food you prepare.
• Seasoning is necessary for cast iron cookware; Consuming oxidized oil particles daily may seem unhealthy, but consuming too much iron, especially when cooking with a newer or less-seasoned pan, is more likely to have adverse effects.

Does Cast Iron Skillet Cause Cancer?

No evidence suggests that the cast iron skillet increases the likelihood of developing cancer. But if you worry about chemicals and metals leaching into your food, here are some easy ways to reduce your risk.

• Check The State Of The Cooking Equipment. 
• Ensure your cast iron cookware has no chips, cracks, or rough edges that could harbor bacteria. 
• Instead of using aluminum foil or plastic containers, keep leftovers in glass containers. 
• Make do with wooden or silicone spatulas and spoons. Scratches from metal and hard plastic utensils can allow bacteria to thrive on cookware surfaces.
• Keep acidic meals to a minimum if they are cooked or kept in metal. Acidic foods like tomatoes, citrus, and vinegar can accelerate metal-leaching. 

Is Cast Iron Healthier Than Nonstick?

The PFAs and Teflon coating on nonstick utensils are dangerous forever chemicals that can hurt your health.

Instead, cast-iron cookware provides a sturdy platform for your meals and boosts their nutritional value by adding iron (In small amounts). Make nutritious meals, then eat them!

Is iron good for health?

The human body needs iron as a mineral for proper development and growth. Myoglobin and hemoglobin, proteins found in red blood cells, transport oxygen from the lungs to the rest of the body, and iron is a necessary component in their synthesis. The production of several hormones also requires iron.
