The Health Hazards of Cast Iron Pans

by Sarah Healthy LivingComments: 202

cast iron pansGiven the amount of time I spend in the kitchen preparing meals for my family, you might be surprised to learn that I do not own any cast iron pans. What’s more,  I don’t intend to purchase or use cast iron pans anytime in the future (I choose to cook in toxin free, traditional clay pots).

This may seem like heresy particularly since cast iron skillets are almost universally considered to be a healthy and durable choice for preparation of homecooked meals. However, I have good reasons for my head scratching decision, and science bears out my serious concerns about using cast iron pans unless they also include a quality enamel layer to prevent contact of the food with the iron surface.

Excess Iron is a Health Hazard

My primary reason for opting out of cast iron revolves around the health problems caused by excess iron in the diet.

Women do not typically need to worry about this problem as long as they are still menstruating as losing blood each month is a protective factor against this condition.  Growing children also are not particularly susceptible as growth obviously requires more blood and more iron.

However, for adult men (even fully grown young men) and menopausal women, cast iron can definitely pose a problem as the iron that naturally gets into food from utilization of this type of cookware can result in iron rising to toxic levels which is associated with a host of serious health conditions.  Iron is one of  the few minerals we cannot eliminate except through blood loss, therefore supplements should never contain iron and cooking with cast iron is a questionable choice for this segment of the population.

Most people view iron as a nutrient, and indeed it is.  It is also a powerful agent of oxidation in the body, which means it increases the chances of cancer and can severely damage the heart, arteries, and other organs when intake is excessive.  In addition, persons with an inherited condition called haemochromatosis, or iron overload disease, can be especially harmed from iron intake.  If you have any family members with this condition (about 1 million Americans), you should be especially careful with sources of iron in your diet.

Iron Overload Symptoms

Unfortunately, the symptoms of iron overload are similar to those of other conditions, therefore it may be wise to request a transferrin saturation test at your next check up to eliminate iron as a potential source of your health woes if you suffer from any of the following and are an adult male or menopausal female:

  • Fatigue
  • Joint or muscle weakness
  • Mysterious stomach or other gastrointestinal pain/nausea
  • Weight loss that cannot be explained
  • Elevated liver enzymes
  • Shortness of breath
  • Early menopause
  • Loss of sex drive
  • Impotence
  • Loss of body hair

Later stage symptoms include:

  • Greying or bronzing of the skin
  • Blood sugar issues
  • Irregular heartbeat
  • Liver problems
  • Arthritis

If you’ve been cooking with cast iron for a long time and are an adult male or menopausal female, it might be wise to donate blood on occasion to reduce iron stores and switch to another type of nontoxic cookware such as enamel, glass, or titanium.

Anemia Problems Are Usually an Imbalanced Gut – Not Inadequate Iron Intake

Believe it or not, there is plenty of iron in the diet of the typical American. There is almost certainly adequate iron intake for a person eating a diet based on traditional foods and even in the diets of vegetarians.

Therefore, if you are anemic and feel the need to use cast iron to increase your iron levels, you may wish to consider an imbalanced gut as a  more likely source of the problem as common gut pathogens consume iron and are a frequent cause of anemia.   These pathogens include Actinomyces spp., Mycobacterium spp., pathogenic strains of E. coli, Corynebacterium spp., and many others.

Increasing iron intake with cast iron only makes these iron loving pathogens grow stronger and does little to remedy anemia.  Therefore, rebalancing the gut with beneficial bacterial strains through diet and lifestyle changes rather than use of cast iron or iron supplements is the best approach to solving this problem.

    The iron from the cast iron is called inorganic iron which the body cannot use, your body can only use organic iron. So any iron that gets into the blood from the cast iron won’t help your body any. Stainless steel pots and pans are fine as long as they are not overly scratched. the nickel in stainless steel can leach into your foods depending on how acidic the food is. I mainly use a stainless steel pot for boiling water for pastas etc. Ceramic coated frying pans are the safer off them all, but I’ll still use my trusted Cast Iron skillet as long as I keep it properly seasoned and dry. And its just not the pan you cook with. Look at what utensils you are using to cook with. A lot of people use the stainless steel utensils and scrape a lot of that crap into their bodies. I always use wood or utensils with food grade silicone, and I have one or two steel spatulas. Mainly use wood though as much as possible.

    There is no 100% safe way to cook, but all you can do is eliminate as much toxic material going into your body and occasionally do a body detox diet.

    I get frequent blood work, at least once per month, and my hemoglobin and iron levels are always within normal range. I use cast iron cookware, as I am vegetarian, to increase iron consumption. To make sure I don’t get anemic, I also I take a multi-vitamin/multi-mineral everyday that contains iron. I have never had iron overload. I am have not passed menopause yet. When I do, I will take less supplements. The best thing to do is to ask your doctor or dietitian to make sure that we are getting a good amount of these important minerals in our diet.

      Blood work at least once a month? Wow, that seems seriously over the top medicalization to me.

      Also, menstruating women are NOT likely to have this problem because they are losing blood every month. As stated in the article, adult men are the biggest risk with middle aged/older men the highest risk.

    Well my great grandfather lived to be well over 100 and cast iron is all they had to cook with. My grandmother 86 and her sister 96 both have used cast iron all of their life.

    So if there were great health problems you would think all the old people I know who cook with it in the south would have died at a young age.

    Stainless steel can be scratched so where does that go. Enamels contain lead now some Le Crueset products are made in china!!! All other cookware has a long list of problems too except for lead free glass which I love.

    Most woman don’t eat a lot of red meat so our iron is usually low.

    So I say season it well with grape seed oil and store it properly cook in it properly and you would be fine.

    Oh and my great aunt was almost 100 and she used it all of her life too. hmmm.

    Then there’s my health concerned mother-in-law she weighs 114 lbs her whole life and who used any thing but cast iron and she’s almost dead at 77 and has been very ill for about 15 years now. She used stainless.

    I have heard doctors say it’s extremely hard to take in the iron from cooking in it. So we breath toxins every day. Toxins are in the air and water etc so just enjoy life eat healthy and live.

    Found this study which clearly mentions “Study reports on nickel release from different grades of stainless steels clearly show that even in the worst cases, the Ni release from stainless steels is usually clearly below the limit of 0.5 µg/cm2 /week. Only studies with one grade (AISI 303, high sulphur content) have shown release rates above the limit.”. Guess SS should be safe for all kinds of cooking.

    Interesting article and perpective, but I believe oversimplified. There apparently is evidence that iron cookware can add some iron to your intake; and iron overload is a hugely overlooked problem.I know, because I have an overload problem that is genetically induced. However, I also just bought iron cookware because I’m tired of eating Teflon. I donate blood 4-6 times per year and have my iron levels checked annually. They are now nearing normal levels, and I plan to aim for an optimal level of 50-100 micrograms per milliliter. Iron tests are almost never part of a normal physical; the should be. Everyone should have their iron levels checked; donate blood as needed to bring it to an optimal level (the very low end of what’s considered normal); and if this were done, it might preven vast amounts of health problems. Iron cookware, per se, is not the problem. The problem is a complete ignorance of, and lack of action about iron overload issues.

      Sorry to use your post as a starting point but I couldn’t find a “post reply” option. So first of all I agree with you. People that use Teflon just don’t realize how many pieces of that stuff gets scraped into every meal they cook. It’s a poison and was NOT designed for long term use as cast iron was. I grew up with the ol’ cast iron skillet and proudly use one today. For anyone to become afflicted with “iron poisoning”, you’d have to probably use the stuff for every meal, every day for years. I’d be more worried about overdosing on iron from supplements than I would be cookware. Secondly, going back to the Teflon issue, unless one replaces their Teflon coated cookware every six months or so, you my friends, are the ones in danger of food poisoning. Not only from the Teflon itself, but also from the left behind food particles that it absorbs. If you are to really against cast iron, the buy stainless with copper bottoms. . .but I hope you know how to cook! :)

    Thanks Sarah for saying this. I read about 20 years ago that cast iron cookware was identified as a major cause of liver cancer particularly in developing countries. Iron is ageing and not something you want to add to your load, particularly if you are post menopausal or not allowed to donate blood. For those suggesting lack of evidence they also do not cite any studies about the long term use of cast iron cookware on mortality, because they don’t have any studies. There seems to be this huge sales job going on with cast iron cookware on the internet which is quite recent. Dr Mercola sells some ceramic cookware for those of you wanting a healthy option.

    Please share your sources that Cast Iron cookware is a source of Iron overdose.. There is such a small trace of additional iron in a final cooked food that the only way for a person to to O.D. on a CI pan would be to eat the pan.. Considering for almost a century Cast Iron was the primary cookware on this planet I find it amazing that we have all survived.. And the claim that we can’t eliminate if from our Bodies???? Really???? The most common cause of that problem is an hereditary disease known as Hemochromatosis……

      People have been using it for a long time and MOST of them have been fine. Just like most people don’t get cancer. But iron in cookware can be a problem for some people, and that problem can be fatal. For them it’s not so much case closed as casket closed.

      That’s not how it works. I work in healthcare field. What it comes down to is individual vulnerabilities. One person might be fine with higher levels of Iron while another person can develop toxicities. We see same thing with smokers. Some can smoke for 70 years and not develop lung problems and another can smoke for 20 years and develop advanced COPD. Everyone has disease process they are vulnerable to. It depends on if those vulnerabilities are triggered enough to initiate the disease process.

    I recently switched to cast iron pans, mostly because I got tired about replacing my cookware every 2 years. So, I switched to the all American Lodge pans. Although they are pricey in my part of the world, they still are a lot cheaper then Le Creuset or Hackmann.

    Before switching to the scientific part- the shocking truth was how much tastier everything seems to taste. I was truly amazed.

    OK now the scientific part – as always, the truth is somewhere in the middle:

    According to some studies (e.g. apparently it CAN add to your iron intake:

    ABSTRACT: Amounts of iron released from iron pots vary from meal to meal. The effects of salt, pH, and organic acids as iron chelators were studied. Maize (corn) porridges were prepared in a cast iron pot from maize flour and 12 aqueous solutions with different pH (3.7 or 7.2), salt contents (0% or 0.5% NaCl), and organic acids (1% lactate, 1% citrate, or none). Salt had no effect, but acidic pH or organic acids (citrate > lactate) significantly increased iron amount, from 1.7 mg to 26.8 mg Fe per 100 g. The amounts released could be important in the treatment and prevention of iron deficiency.

    These levels are nothing to be worried about. And I will, for sure choose cast iron again.It is imho opinion, the safest, and tastiest way to cook.

    Hi, I work in the lab of a foundry that produces cast iron products. For any iron to transfer from an unprotected cast iron pot you would have to generate heats that normal every day cooking would never reach, cast iron also contains traces of lead, copper, aluminium, phosphorous and other elements that on their own are not good for ones health, however when mixed as an alloy of cast iron they are trapped within a complex matrix and so harmless. Stainless steel is also an alloy with iron in it but high chromium level protect it from rusting. I understand people want to be health conscious but I use cast iron cook ware with no worry. Hope this helps.

    I have heard a lot of this information and I have always made sure to properly season my cast iron and I use enameled for cooking sauces that have acidic properties than will eat away your seasoning. I believe that if you take care of your cast iron and keep it seasoned properly, the iron leaching into your food is negligible. You have to look at all the facts and who puts the studies out there. Here’s a fact: Once you buy cast iron you never have to buy anything else, ever.

    Now who hates this? People that market cookware of other kinds. Nothing against this site because i do believe the author has only the best intentions into maintaining our health. The internet and media is loaded with studies that are backed by marketing campaigns for the sole purpose of separating people from their hard earned dollars. I will never give up my cast iron. My father still cooks with it constantly and he has no problems with iron related disorders at all.

    So many experts want to criticize this blogger, I certainly appreciate your insight and expertise. As a diagnosed sufferer of Hemochromatosis, let me enlighten everyone to two facts that no one seems to know through their extensive online research, 1. Every physician I have ever seen for treatment of this condition instructed me to NOT use cast iron cookware because I need to avoid every source of additional iron beyond that which is naturally occurring in the food I eat. 2. Hemochromatosis is much more common that people realize but goes relatively untested thus untreated. People die from it’s side effects never realizing Hemochromatosis was the real cause for their heart attack or cancer.

    What she is telling you is not a scare tactic, it is just information she didn’t cite well with references. Many people, especially anemic women could benefit from cooking with cast iron but everyone should consult with their doctor before making any decisions about their healthcare.

    The worst problem is in cooking acidic foods like tomatoes, vinegar, etc. They will leach iron out of your pan, which makes them taste rather metalic too.

    I apologize in advance for my bluntness, but this article is nothing but a bunch of bad facts. The human body only absorbs as much iron from the diet as it needs, which is why excess iron is excreted in feces and will turn it black. There is a rare condition in which the body absorbs too much, but that is MUCH more uncommon than anemia. Shame on you for discouraging the use of cast iron because many more people would benefit from using it than wouldn’t.

      Iron metabolism is still very poorly understood. It may be implicated in many common disease processes and not just in those people who have genetic hemochromatosis (iron overload). My iron levels increased dramatically after 1 year of regular use of cast iron cookware which took me well out of the healthy range. This was discovered when I had tests to see why I developed back and joint pain during that period despite not having any injuries. As my iron levels diminish – through giving blood – the pain is slowly, very slowly, subsiding. Which is good because even strong prescription painkillers did very little.

    Here’s the thing:

    1) I don’t doubt that people can get an overload of iron. BUT, this article doesn’t discuss if, in fact, a traceable amount of iron is absorbed from food cooked on cast iron. I’ve heard from other sources that the iron from cookware is not absorbed.

    2) The philosophy behind this website is that of using traditional food preparation. Well, guess what? Cast iron has been in use for hundreds of years. One would think that concerns about using cast iron cookware would have surfaced earlier.

    3) The entire conveyance of this information is that of a “scare tactic”. Classic “tells” of a scare tactic include sharing controversial information about a topic of little consequence, while providing no referenced backing and no alternatives to the thing being bashed (Unless you’re a millionaire and can afford the gold-plated version of everything). Unfortunately, I’m seeing a trend of scare tactics in recent posts on this website. Certainly, sometimes the truth and facts are little-known and not well-received. (Take the truth about “healthy” fats like margarine!) I’m all about listing to the little-known voices, especially in the medical/health realm. But when a source is frequently and consistently “discovering” controversial information that has little to no scientific or historic backing, it makes the source less than credible. At this point, I feel this website is drawing at straws simply to keep fresh content going. I am disappointed, since I’ve appreciated and respected Sarah’s research in the past.

      A really well seasoned cast iron skillet cooks the best slow cooked scrambled eggs ever :)

      Using the stainless steel I find if you heat the pan slowly wait for it to get really really hot and then really really really hot then drop a drop of water in and see if it dances across the pan is a good way to learn if the pan is at the right temp. Then add oil or butter just enough to barely coat the pan and then when the oil is hot add eggs and cook how ever you like. It takes a bit to learn how to keep an egg from sticking but I find a little olive oil with a little butter works great.

      Don’t know if that helps there are big differences in stainless steel cookware brands.

    Hello Sarah,

    Your claims are not backed up by any cited research. The iron given off in American made cast iron cooking is miniscule. It does improve an iron poor diet. There is no proof that it harms menopausal women or men. It also is broken down in the body to be excreted. It also can be excreted whole through defecation. IT IS THE ONLY WAY OXYGEN IS CARRIED TO CELLS. It constipates the system because it has an Iron binding capacity that BINDS. Therefore if you have average to high iron levels, it is a good idea to regularly take stool softeners. New research is old research. There is growing eveidence that a theory produced in 1934 is correct in killing cancer cells. That is the ability to oxygenate cells, increasing ooygen inside a cancerous cell, thus killing it. Most cancer cells survive, mutate and grow through aneorobic means, i.e. fermentation and acidosis. It is the sugars from aneorobic conditions that feeds cancer cells. Oygen litterally reverses this process and eplodes and kills CA cells. Again the only way O2 gets into cells from the blood stream is through Fe+ or iron carrying through the blood.

    Cast iron cannot be that bad using it just a few times a week. You stated that oxidation causes cancer ? Wrong ! It fights cancer cells and free radicals. Although you do have a point. You must be middle aged, using cast iron for breakfast and dinner cooking ? Users that use it 2 to 3 times a week may be good for you.

    My wife and I have a chronic iron deficiency. In my wife case, it is really bad. We bought a whole Lodge Signature collection from the USA to cook two years ago. My levels of iron are now normal. My wife’s level improved but were not sufficiently good, so she takes some iron suplements sometimes.

    We were going to buy unexpensive old French cast iron pottery from the late XIX and early XX century, when we discovered that the old sale brochures (from 1914) of Pied-Selle cast iron (from Fumay in France) had a mild cover of tin. Then we realised that we have to buy something modern and made in Europe or in America, not Asian and not old, that is truly safe (no tin or heavy metals).

    The choice was then between the only two US or EU manufactures of non-enameled cast iron cookware: Lodge from the USA or Skeppshult from Sweden. We choosed Lodge Signature because it was the most beautiful one.

    I have cooked in and have had my meals prepared in cast iron all my life. I have no intentions of using other alternative cookware. I have two stainless steel pans that I use rarely. I have generations of family that have used them, some I have are handed down, others purchased used 36 years back. They are well seasoned, and I occasionally reseason them. Most of what I use are over 50 years old and ALL made in USA. A rarity now. I have never heard anything so negative about cast iron skillet cookware before. It will be just a matter of time before other cookware will be in the spot light, titanium cookware included.

    I love cooking with my cast iron pan and I am a young male adult. I give a pint of blood every 2 months so I’m not worried about iron build up. Cast iron pans, like every other kitchen implement, has its time and its place. I wouldn’t recommend using it for everything, but it has no equal for recipes that benefit from browning… indoor steaks, skillet potatoes, etc. I agree its not the end all, be all, pan, but I strongly recommend having one on hand.

    I am looking at cookware from a health POV and also looking at cooking for ‘survival’. I don’t like aluminum, not crazy about other cookware and am investigating others. BUT, is there anything besides cast iron that can be used over an open fire or campstove? To me that is a big issue in this day and time.

    Sarah, in your blog (castigating cast iron cookware, I see absolutely no documentation of your charge against cooking in cast iron. Even the doctor in your source doesn’t refer to cast iron. I wonder if somehow you have ever looked into the dangers of teflon in ones diet. It is a given that it leaches into the food we eat that was cooked in a pan coated in the stuff.

    A wee tad of extremism here? There’s so little risk of iron toxicity from cast iron, this position is really pretty over the top. Especially from a well-seasoned pan which puts a barrier between the pan and the food. If you already have iron toxicity (almost certainly not CAUSED by your cookware), by all means lay off the cast iron, but this is a case of a little bit of knowledge leading to a ridiculous assumption being passed off as fact. Look at a few dozen other sites seeking out the stats, as I have been doing, and you will find no need for such dire action against your lovely cast iron ware.

    If using glass cookware make sure it is made out of BoroSilicate Glass. This is what the Europeans used and it was awesome, this is also the way pyrex used to make their cooking glassware. Now Pyrex uses soda-lime glass.

    Le Creuset is very good for enamel.
    All-Clad is one of the best if not the best for Stainless Steel.

    Hemochromatosis runs rampant in my family. There is a genetic test for it, to know for sure. (1 in 8 Caucasian Americans carries it, by the way). It’s highly manageable by donating blood regularly (or getting medical phlebotomy every couple weeks if your iron is reeeeaally high). Ask your doctor for your iron levels (cheap and easy) if you can’t afford the genetic test. Also, enjoy a cup of iced tea with your cast iron cooked meal. Tea blocks iron absorption. Don’t panic, be informed. Hemochromatosis is only a danger when you DON’T know if you have it.

    Dear Sarah I wanted to know if cast iron pans were safe so I went to the web site and found you. I’m so glad I did. You helped me alot to understand about cast iron pans. My mother grew up using them and I started using them when I got married. But a few years ago I heard it was bad to use them so I stopped. I really didn’t understand why they were bad until I read your article. Thank you so much for all the information. If you can please let me know which brand is safer to buy I would appreciate it. On Sept 10,2011 Melisssa’s comment at the end of her letter about Dr.Mercola safe set of pots & pans, can you tell me where they are sold. Thank you again for all your Great help.

I am so grateful for it and always seem to trust the advice you give because Iknow whatever you post you have put time and research into & deem it safe for your family, whereas I feel like I don’t have the time to do as much research because i have 3 children under the age of 3 so things tend to be a bit crazy :) (in a good way) I was curious what you think about Dr. Mercola’s Ceramic cookware (that supposedly??? isn’t supposed to leach anything?) I currently own Calphalon one anodized pans (Not sure how bad those are for you?) a Large SS pot for making stock & a cast iron pan for frying eggs. I definitely would like to replace them with what would be best for my family, but tend to get overwhelmed in figuring out what!!!! I know you posted enamel (no lead), glass and titanium are best. Do you have any brands, links, or any pans specific you would feel safe using for your family? And is that Dr Mercola set safe & a good option or is there another set you would recommend?

    Thank you so much for your help! I greatly appreciate it! Blessings, Melissa

    Ha! I guess there’s more than one way to cook an egg! I have great luck using a small stainless skillet with a heavy base (like All Clad or Emeril copper/stainless base). I heat it on super LOW heat and use homemade lard for the fat. It doesn’t stick at all — in fact, it practically floats right out of the pan. I fry farm-fresh eggs this way, low and slow, sunny side up, and it cooks the whites nicely while leaving the yolks less cooked, preserving their yummy goodness.

    I really want to impress upon people to do their own homework and not allow fear to guide them.. as even HHE admits there are no studies that show cast iron usage directly causes abnormally high levels of iron. Abnormal Levels in the body are an indication of Dysfunction in the body and the mechanism that shuttle iron out of the enterocytes and into the blood.

    Just because your diet has iron in it from food or from cast iron…does not guarantee it is actually absorbed much less USED in the body. Prenatal vitamins that have iron in them often use an form of iron that is not good for the body and actually causes elevated iron levels. Iron from cast iron is not a significant source of iron in the diet… if you are consuming lots of greens…. they have quite a bit of iron as well…as do meats. So if you are allowing your fear to guide you…cut out meats, beans, veggies, grains….etc And go on an air and water diet.

    I PAYS to understand how iron is absorbed….:

    Once you understand that the body actually controls it’s usage of iron… and it’s levels…. (unless there is a dysfunction present) you realize that if cast iron has been used for such a LONG TIME with out widespread excessive Iron levels… that it is pretty safe unless YOU, The individual, has a dysfunction that affects iron levels in some way.

      Hi EM, again … iron used in the past was by people who did not have the guts that are in the terrible shape of modern people. Even folks like me who eat well have very poor gut function compared with the pre-antibiotic/ pre-baby formula age. Folks like me (who are the majority of people) have imbalanced guts despite all our best efforts because the gut wall was improperly populated from the get go. We manage it with good diet, lots of probiotic foods, etc, but the fact remains that our guts hold the key to our absorption levels and people without excellent gut function (almost everyone) can be more easily poisoned by metals than folks who have excellent gut function. You cannot compare the 2 populations as Traditional Cultures had no pollution, no antibiotics, no birth control pill, no processed foods etc etc to mess up their gut flora.

        If the villi are as damaged as is supposed today… then you run into BOTH issues of poor performance in regulating absorption/usage AND the inability to ABSORB. If you are warning people about iron… you SHOULD have made gut health a major portion of your article… as such, you did not. You made it about cast iron…. not about the health of the individual and ended up spreading your own fear to others instead of providing the full information. I am not debating your intent… i am presenting the reality of one of the affects this article had. You only focus on the health of the gut being involved in the deficiency of Iron…when it is involved in both sides of the spectrum.

        I appreciate your blog as do many people…and what i do not like is having to do damage control (not here but in other places) from the fear triggered by the incomplete article…. by providing the rest of the information that should have been provided.

        I completely agree that we can not compare traditional cultures with modern…. and had you included this reply to my post in your original article…. you would have a lot less people focusing on cast iron… and a lot more people focusing on getting their gut health improved. 😉

    I don’t own any cast iron (except an enameled La Creuset dutch oven), but I still found your facts about excessive iron quite interesting. My husband sometimes suffers from IBS and other GI problems, fatigue, and joint pain. We’ve been trying everything to help him out. This spring, he gave blood, and reported that he felt a ton better. His problems have been much less ever since. He used to give blood all the time, and didn’t have these issues then, so I wonder if it might be related!

    Personally, I think men are given extra iron with the expectation that they would be injured more often while hunting or defending the tribe. In our modern, less violent and physical society, men aren’t shedding blood as often as they used to, so giving blood is a good substitute (and a very generous action!). I myself often have low iron, so I don’t worry about it so much, or for the baby either, but I think my husband would benefit from making blood donation a regular thing. Thanks for the info!

    Just wanted to share my story about this.
    I recently went to my MD because I have been exhausted constantly. He did a slew of bloodwork and found that my iron levels are elevated. All other numbers are ok, or so he said. I haven’t seen the results with my own eyes yet.
    Just a little history though, I have 19 month old twins and during that pregnancy I became quite anemic as multiple moms tend to do. I refused to take their iron supplements and instead took a little floradix instead. My numbers came up just enough to go ahead with a homebirth and then I stopped taking it. But what I started to do and have continued doing is COOKING WITH A CAST IRON PAN. Then my numbers came back high.
    I have become MORE tired over the past 6 months even though the babies sleeping patterns have improved. And I was cooking everything in the cast iron pans all along this time. So for the past month and a half or more I have stopped using my favorite pans and am due to go have my bloodwork repeated. I am even more curious now to find out if my levels went back down after reading this article. And as soon as I can find the time to escape my house and two of the cutest crazy babies, I’ll get to the lab! I can say that I have been feeling a little bit better the past couple of weeks but we’ll see if it’s related to this or not.
    I have never cooked in glass or enamel (yes, lead free, I know…) or even heard of titanium pans. Unfortunately, they would require an investment that I probably can’t make since I am not working right now. I’ll just keep scraping my stainless.

      Thank you for sharing your story, Elizabeth. I was greatly encouraged by my midwife to switch to cast iron when I was pregnant to ensure safe iron levels, but I never would do it. She said she never saw a pregnant woman cooking with cast iron that had low iron levels .. I’m sure that was an exaggeration and there are exceptions to that, no doubt, but it goes to show that cast iron in her experience (many years as a midwife testing hundreds of ladies for iron levels) cast iron has a significant impact on iron levels.

    I have one cast iron skillet that I love very dearly. I use it several times a week to fry eggs and bacon. I love reading everything you post Sarah, but for now, I’m sticking with my beloved cast iron skillet from my Mema. The rest of my cookware is Al-Clad. I paid a lot of money for good sturdy cookware and I hope that as long as the ingredients that are going in it are healthy that the leeching will be minimal.

    My husband and I once were invited to this dinner party where the guy was selling cookware called “Salad Master” the price of this cookware made my Al-Clad look like I got it from a thrift store! The theory was that this awesome “salad master” cookware was not supposed to leech ANYthing into the foods. They did a horrible taste test with baking soda but the entire presentation felt like a huge sham to me. Maybe there was something to their skillets, but then again, it might have been all smoke and mirrors. We did not purchase anything that night and I’ve been happy with my cookware!

    Thanks for keeping us thinking!

    I cook eggs in my All-Clad skillet all the time. Here is what I do. Heat the skillet gently before adding fat. Add fat and allow it to heat – then add eggs. If you scramble them – let them sit for 3 minutes w/o stirring & then stir. This generally works for me. And the butter doesn’t burn either.

    Julie, hemachromotosis organizations state that you do not need to eat a low-iron diet, b/c dietary meat doesn’t contribute to the problem. I haven’t seen their stance on cast iron, but the reality is, stainless steel leaches nickel, most enamel leaches lead or other chemicals, Teflon definitely leaches all kinds of chemicals, and I’ve never seen a glass skillet. Properly seasoned cast iron turns the coating into a polymer which I seriously doubt is leaching. I want to see some hard proof via properly controlled studies showing ferritin levels rising to a dangerous level when cast iron is used regularly.

      I have not personally seen any hard data on it. I have seen plenty of places that talk about using cast iron to boost blood iron levels. I do not feel comfortable waiting for a study to say its dangerous before playing it safe. The cautious choice would be to avoid it, i think. Obviously an occasional meal is not a big deal. I would worry more about all the aluminum they use in the preparation of food in the restaurant industry. But, it is indeed something to ponder and think about which is why I posted about it for those who might have some issues and not be aware of the potential dangers.

    Sarah, I think it’s also important to think about meat factor. Meats like hamburger have a lot of iron too. If you are not cooking with cast iron due to worry of iron in your food are you eating heavy iron meats like cow meat? It it certainly something to be aware of in your cookware, and it is important to use safe cookware, but if you use your cast iron CORRECTLY without acidic things and have it well oiled it should leach very little iron into your food and be nothing but your friend. If you are worried about exessive iron I would be more corncerned about the high levels of iron in meat foods.

      Good point! Its true that men aren’t losing iron on a monthly basis in the same way as women, but they still need it as it is vital for red blood cell production. The absorption of iron from the diet is variable based on the requirements of the individual, therefore if you are fit and well (and in this case male) then you are incredibly unlikely to get iron overload.

      I think you can get ones that are full titanium as well last I checked. Everybody freaks out about aluminum, but it is not a problem unless it comes in contact with the food. So a titanium coating should be fine. Aluminum really leeches if you scrape it with cooking utensils (metal ones), for example, which is one reason aluminum cookware is so bad. If you aren’t scraping it so that it gets into the food and it’s not contacting the food anyway, that should be quite safe. Most ice cream makers have an aluminum interior (mine does). No big deal unless you go scraping the ice cream out with a big metal spoon.

      Ceramic cookware is NOT enamel! Enamel is glaze-coated metal. Ceramic cookware is glazed ceramic. Stove-top ceramic is specially formulated to resist the thermal shock. It will break if you drop it.

      I just thought that you didn’t seem to tell the whole story, or give any hope for people now left in the dark. Cast iron cookware may not be for you and your husband, but it is a much safer option than what most people are cooking with. There is significant evidence that the absorption rate is much lower than that of food. The fact that you didn’t have any sources threw us all for a loop too, I believe. Also, the body does eliminate iron through the sloughing of the intestine, which happens about every week or so.

      Please don’t feel like we are attacking you in all of these firey comments. There may just be a little more to the story. This is great information, like you always give to us! Thank you!

    Because I have used cast iron — almost every day — for literally decades (I’m 55 yrs old), and recently heard that post-menopausal women can inadvertently overload their systems with iron from cooking in cast iron, my naturopath and I thought it would be a good idea to test ferritin (iron) blood levels. Not only were my blood iron levels in the normal range, they were on the low side–which is my normal level and consistent with my lifelong health history. Meaning, cast iron made no difference at all. Since cast iron has been used on a daily basis by thousands over several centuries, I don’t believe cooking in cast iron affects the overwhelming majority of people. Perhaps a few, very rare, bizarre cases, but, isn’t that true of everything? I suggest everyone have a ferritin test done, and once you see everything is normal, go back to enjoying cast iron cooking. There’s no better way to cook (okay, stainless steel is better for a few things, but cast iron still rocks).

      I agree with Deb here. If you are worried, get a blood test. Do NOT go out and buy new cookware because of this article. A blood test, which most insurance companies will pay for, will probably alleviate any fears. You can get it tested once a year to make sure you are in the clear. I just had my tested and my iron levels are wonderful. I’ve been using cast iron daily for a few years. My husband is in the Army and they test his blood all the time. He’s fine too. I think the information here is, like Deb said, for the absolute minority.

          I agree with Deb and the others here. I have read articles about the dangers of stainless steel in leeching heavy metals as well. I think it is just too easy to worry too much about all of this. I say if Ma Ingalls used it (and many, many, many of our foremothers) without any known issues then it’s not too big of a deal. But getting a blood test if you are worried is a far better idea than buying a new set of cookware.

    I can’t give blood because I have cancer, but anyways, I’ve looked for good cast iron skillets just to use now and then & as soon as I find one, even the tried and true good brands, u scrape ur fingernail on them & this rust or black stuff comes up. Is that the iron? That would end up in our food. I dont understand it. I really just want one of those cast iron pans that u put corn bread mixture in and it shapes it like corn cobs…like the pans at cracker barrel. Can someone explain what that coating is that comes off and is that what iron is that gets in ur food??

        If you are buying NEW cast iron BEWARE!!!

        First of all, ONLY buy LODGE – it is made in America. ALL OTHER BRANDS ARE MADE IN CHINA = TOXIC additives!!!

        Second, even if you buy new Lodge, it comes “pre-seasoned.” You MUST REMOVE their SOY-BASED “seasoning” and re-season it yourself!!!

        I would scrub the heck out of it with dish soap and a copper scrubby until nothing comes off. Dry it off thoroughly.
        Then, put it into a cold oven and turn it up to 350-400 degrees and let it heat up for 30 minutes or so (after it hits temp), then use a fat of your choice (lard, coconut oil – NOT a liquid oil) and rub the ENTIRE pan with it (bottom and handle as well) and put it back in the oven for 15 minutes. Remove pan and wipe off any excess grease and char. Re-apply more fat all over, put pan back in oven, turn oven off and allow it to sit inside as oven cools. After 20 minutes or so, remove pan, wipe it all down, and re-apply another thin coat of fat only on the inside, put back in cooling oven and leave until oven is completely cool.
        Season pan on rack in middle of oven, and put the extra rack below it with tin foil or a larger pan or cookie sheet to catch any fat that may drip down.

        This will create a safe, initial seasoning. A well-seasoned pan happens over time with use – from the fat you cook with.

        NEVER WASH A CAST IRON PAN WITH SOAP AND WATER!!! To clean it, simply wipe it off after each use with a paper towel. Store it in a CLOSED, dust-free place – otherwise dust will adhere to the seasoning! I store mine in the oven.

        If it collects grime or you burn something realy bad, you can clean it by pouring some boiling water into it while it is on the stove and adding a bunch of salt and let it boil and scrape out any crud. BUT, you MUST immediately dry it off (while hot), put it back on the burner and re-season it with fat.

        Soap will destroy the pan if used more than once or twice every ten years or so, and water will cause it to rust. So, always make sure it is fully dry before storing.

        You can salvage an old rusty pan by either washing it off and then heating it up really hot and scrubbing off the rust, or even just try heating it up really hot and scrubbing off the rust (depending how bad it is). Then, immediately re-season it as above.

    I have enamel, stainless steel and cast iron… they all get used regularly and each have their place. Given that every cookware I’ve heard of has some sort of issue, we will continue to utilize cast iron as our primary cookware. Cast iron presents far fewer health issues than teflon, aluminum or low quality stainless steel. The issues stated with cast iron are easily solved by donating blood and that simple act will not only help the donor eliminate excess iron it may very well save someone’s life.

    Cast iron is one of the oldest forms of cookware. Most of the healthy peoples studied by Dr. Price used it. The long lived peoples who have been studied in the last century, such as the Okinawans, Georgians, Hunza’s, etc, all use it. These peoples often lived to their nineties and even longer, remaining in excellent health, often eating food cooked on cast iron cookware every day of their lives.

    I cook on cast iron every day, and have done so for almost forty years. Yesterday I used it three times, which is not uncommon. My mother cooked with cast iron, so I have had food cooked on it on an almost daily basis for over 50 years. No symptoms of iron toxicity, and my blood iron content was always ideal, when I had blood tests.

    That said, many people suffer from iron toxicity. But as I understand it, this toxicity is caused by the forms of iron added to supplements, and used to “enrich” breads, flour, and other foods. That form of iron is quite different than cast iron. These forms of iron were never placed into human bodies until the twentieth century.

    People have been using cast iron for thousands of years. I have never heard of cast iron pans causing this problem. If you have can refer us to some source material that supports cast iron pans causing iron overdose, I would like to review it.

    I would never take a supplement containing iron, or a food product that was “enriched”.

      It is my understanding that iron is iron where ingestion and toxicity is concerned. My research on iron overload does not specify that one type of iron is ok and another is not. All sources are a threat. I think its an important point to make that the folks studied by Dr. Price didn’t have imbalanced guts either and an imbalance of gut flora contributes to absorption of metals to toxicity levels.

      It is true that the absorption of iron from cookware vs the absorption from food is different. The body doesn’t absorb all iron anyhow, because it know too much is a bad thing. The absorption from cookware may be as little as 2%.

      I quite agree. I sure hope, Sarah, you didn’t base your entire article on the word of Dr. Weil.

I’ll need more than that on which to base an opinion against cast iron.

      Mercola sells cast iron pans and he has hemochromotosis, as did his father (so stated in one of his articles). Ok then. Is he a salesman or what??!

    I am not convinced that the increase in iron with most foods is significant. A study I read indicates that acidic foods cooked in iron does raise the iron absorbed significantly, but a steak or hamburger in an old cast iron pan is very, very small. I actually have the genetic propensity to haemochromatosis and am post-menopausal. My iron levels remain in the normal ranges and I use a cast iron skillet for all meat cooking that isn’t grilled, though I do use stainless for spaghetti sauces and the like. I have used my old cast iron skillet for at least twenty years and my mother in law for forty before that. I understand that new skillets/pans cause more absorption than older ones, but still ~ I don’t think using a cast iron skillet even daily for frying an egg is that risky.

    Have you looked into how how much iron truly does leech out, especially in a well-seasoned pan? The coating of grease/oil on a well seasoned pan can protect certain leeching properties. This is why tomatoes and other acidic foods can actually be cooked in cast iron, although only if the pan is well seasoned. As you use your pan it builds up a natural coating. Now if you use soap or don’t re-grease your pan after cleaning it, this can present a different set of issues.

    Also, do you have any references for this info.? I would be interested in doing further research. Thanks so much!

      It really depends, Therese, on many factors (heat, cooking time, seasoning of the pan, food being cooked etc). I personally choose not to take the risk at all as there are plenty of nontoxic options for cookware.

Put cold butter in, let it sizzle minute, it will turn a tiny bit brown (yuum, brown butter!) Pour eggs in and if making an omelet, use a thin spatula like a fish-turner. Done in 2-3 minutes and NO STICKING!!

      I make omelets everyday – in an antique cast iron pan well coated with coconut oil and ghee.
      The key to ANY metal pan is to heat it up really hot FIRST, and then add your fat and turn down the heat before you add the eggs to prevent your eggs from burning. I let my omelet cook slowly so it doesn’t burn on the bottom. It has to be hot enough when you pour in the eggs that they sizzle and bubble a bit, but you must immediately turn the heat down quite low as soon as you see the eggs starting to set on the bottom and edges – then add the cheese and cover with a lid and turn to low and let sit until it all cooks through and the cheese melts. It takes some getting used too – too hot and the bottom burns, not hot enough when the eggs hit the pan and the omelette never sets right. Also, even though it finishes on low, it will not burn, but don’t walk away and forget about it – after 10-15 minutes it will taste like chewy cardboard!

      Yeah, I know you can fry an egg on a well-seasoned cast iron pan with no oil – but, sorry, an egg with no oil is DISGUSTING!!!

        I assume this website is American, because that is a very American attitude and not shared by a lot of the world!

        There is no reason at all why people ‘should be getting regular blood work done’ at all. In the UK the general view is that people should not undergo unnecessary tests, particularly invasive ones. If there is no clinical indication for bloods then why have them? In the US attitudes to healthcare are a little different, and if you can charge people for tests, even if they’re not required, then it will happen.

      Hi Teresa, stainless steel has it’s own issues.

You’ll find that people who follow Sarah and the Weston A Price Foundation principles LOVE to eat loads and loads of butter and healthly fats (NOT to be mistaken for vegetable oils) (I’m talking coconut oil, olive oil).

        You make the statement that you’re an expert and yet you also do not provide supporting facts, numbers, stats or case studies. Could you perhaps elaborate?

        Sarah would never suggest someone use Teflon for cooking. The use of stainless steel is by far superior.

        I wish you all the best in getting to know and understand the principles of the WAPF.

        Couldn’t agree more. The opinion appears to be based on some misconceptions. Food cooked in a well seasoned CI pan, the iron. The pan would leach only a minor amount of minerals.

        I’ve used cast iron for years, as did my mother and grandmothers with no health problems.
        The remainder of my pots and pans are tin lined copper. Again, if the lining wears thin, come copper may leach, but not enough to cause a problem. No so with other cooking surfaces. Most leach something. l have heard that stainless is not leach proof,

        I agree, buy American made cast iron. All of mine is years old, most decades old. I don’t like the new stuff, and there is no telling what is in the iron in foreign pots. Season it wall, which requires a little effort, and do not use chemicals or abrasives to clean and you are good to go.

        Opinion, I know, but so too was the article

        Not very healthy Mike?

        We are all FULL of FAT and living well. Source Weston A. Price for more information if you are willing to do some real studies with real results…

        I love my simple but VERY heavy-duty stainless steel small frying pan. I use Smart Balance, olive oil, and so forth — I just use it for scrambled eggs and grilled cheese. But I feel SAFE using it for my little girls and husband. :)

        This is a great discussion!

          Smart Balance is NOT SAFE AT ALL!!!!!! Use REAL BUTTER!!!!!!
          Actually, use Coconut oil and ghee to fry your eggs in a cast iron pan – that’s what I do.

          To Mike – you NEED FAT TO SEASON CAST IRON! 😉

            i hate using stainless steal, i always seem to burn the food (gets hot too fast, even on low heats, that could be partially due to the stupid electric oven though). i agree with mike, cast iron can’t leach out that much and is way healthier than tephlon and way easier than stainless steal.

        Disclaimer: I agree that too much iron is a bad thing. My grandparents both had iron issues… they stopped using their cast iron pans (switched to stainless at great expense) and… lo and behold… no change in their blood-iron levels! Turns out they were getting too much iron from their well water.

        That said, I’m not arguing the point that iron is one thing we don’t need to supplement in our diet… but to suggest that cast iron pans are a source for iron contamination in our food and bodies tells me either you are cooking on unseasoned cast iron, or, you don’t know what you’re talking about/making shit up. Where’s your proof? Where’s your facts? Scientific support? I think you are just in love with yourself and think you know best for everyone.

        Frequent cast iron cooker here… and a scientist to boot… and I am not at all swayed by your “expertise”. If a cast iron pan is properly seasoned, your food will not contact the iron at all. The seasoning (I.E. baked-on oil AKA patina AKA dehydrated, carbonized lipid material) creates a water-proof, non-stick barrier between your food and the iron. IF you learn first how to properly care for your cast iron pans (most include instructions) you will come to realize this yourself.

        For everyone else who is reading this article and ready to throw your pans away, send them to me! OR, stop using soap to wash them (heat over 160*=sterile!) just hit them with some hot water (wait till they cool first!) and scrub them with a copper/stainless scrubby, put them on low heat till they’re dry, then give them a coat of oil or shortening (IMO olive oil produces the best, longest lasting patina, though it takes a few “seasonings” as the layers are relatively thin)

        Seasoning instructions: coat your pan in a thin layer of oil or shortening –

        (olive oil would be my first choice, then crisco-type shortening, things like butter work too but give the food more of an off flavor when baked on… vegetable fat > animal fat for seasoning)

        Once lightly coated, place in an oven at around 400*F, until they stop smoking. This will stink/smoke up your house, so best to do it on a nice day with the windows open. Allow the pan to cool, wipe it with some more oil, and repeat if desired. Some times I use my Misto to hit it with more OO while its still hot, and stick it back in for another round. 3 coats of OO is a great start, and the patina will improve with regular use and proper care. Eventually you will be able to do eggs, pancakes, whatever, with little or no oil whatsoever.

        Eventually you should have a glossy black coating that repels water and food. Acids are your enemy now! You should re-season prior to/after cooking acidic foods, such as tomato based sauces etc. NEVER WASH YOUR PANS WITH SOAP I know we’ve all been brainwashed by DOW Chemical to do otherwise but it is not necessary, as you will see.

        Want to re-season? Run them through a cleaning cycle in the oven and they will come out looking like the day they were cast… oil them quickly or they will begin to rust just from the moisture in the air. Dishwashers work for removing the patina too, but they will come out rusty, and this is not recommended.

        Whoever wrote this article is assuming that iron pans=iron in the blood. I can assure you from experience, both in my own life, the lives of my family, and studies I’ve read myself, that cast iron is the healthiest of cookware that you can use. Once seasoned, they require less cooking oils/fats than any other cookware (aside from “non-stick” chemical coatings, which I hope none of you use) and if properly maintained will last your lifetime. They are durable, inexpensive, though a little heavy, and come in all shapes and sizes.

        For what it’s worth, seasoned carbon steel is very similar to cast iron, while saving some weight. Steel does not heat as evenly as cast, so it’s a trade for the reduced weight, but they both have the same effect when given a nice patina. If the weight of cast iron is an issue, give seasoned carbon steel a try, just use less heat.

          I am a fan of cast iron (remembering my mom killed our Canary when she burned something in a Teflon pan). Unfortunately made in USA cast iron seems to have disappeared. Loge is made in China now, I think. I don’t mind that too much except that they don’t machine the cooking surface any more so it’s not a machined, smooth cooking surface. I can’t imagine that it can ever be good for cooking. Kind of a disappointment for new CI users I’m sure. My tip: buy used; plenty available on eBay.

            Lodge’s non-enameled cast iron cookware is still made in the USA — check their website. Their enabled cast iron cookware is made in China, but according to them under very strict supervision.

        I’m with Mike. It is asinine to publish ANY literature with no scientific research to back such claims. Individuals have been using CASTED IRON for centuries as cookware; and many other applications. I haven’t time to discuss the scholarly articles of well made cast derived from organic iron vs. inorganic iron–but I can assure you that a quick study on Google Scholar will provoke alternate ways of thinking on the subject. And as Mike said: Stainless is the ONLY way to cook and insure a low-lower level of toxicity. However, stainless cookware is not made as thickly due to it’s sheer strength compared to CI thus, causing a lower level of thermal retention (it does not hold heat as well as cast). Therefore, I will stick to the fine art which has endured time– and cook on it as well!

        And doesn’t using a well seasoned pan eliminate much of the interaction between the pan and the food?

        While I’m all with you on this one. I just bought a cast iron pan today [it came from Walgreen’s so I’m not expecting the quality of my Great-Grandmother’s 103 year old pan] and it was made in China. Just so everyone knows that not all cast iron cook wear is made in the USA.

          so after well over a year now, how is your made in China pan doing??? just curious – i bought one at Aldi and it is probably made in China as well and i have an old one i found at a thrift shop – way big difference (then again, if i use my Aldi one more and get it to be old it may do just as well)

      You have lost your marbles. The amount of iron absorb by the body thru cooking with cast iron isn’t really measurable. You need to provide scientific research from a recognized source to substantiate your claims before you publish this garbage as fact
