Everyone absorbs iron in their diet. Some of us can’t get rid of it as easily as others. Are there do’s and don’t, a special diet, forbidden horrors? Simple answer: no, no and no.
Present a medical condition that has something to do with diet and all the crazies come out of the woodwork. Iron absorption is a natural function of the human body. In people with hemochromatosis, it just happens to hang around. That iron is absorbed through your diet but it doesn’t follow that a decrease in iron in your diet will, necessarily, decrease iron deposits in hemochromatosis.
All food groups have iron and we only absorb a small fraction of that iron. There is some speculation that the iron we absorb is of the heme variety, as opposed to the non-heme, but that research is inconclusive. There is another theory that a defect in hepcidin, a circulating peptide produced by the liver, is the defect in hemochromatosis that causes greater intestinal absorption of iron. Heme iron is more prevalent in red meat and vegetarians have lower serum ferritin levels and so the dots get joined and two and two can become five.
Iron supplements in food were introduced as a marketing gimmick in the 1950s and that’s about all it amounted to, a gimmick. Ok, don’t eat raw shellfish, not because of the amount of iron they do or do not contain, but more usefully because of other bacteria.
The one that really gets me going, though, is the assertion that cast iron pots could kill you. Well, I agree, if you want to swing a 12″ skillet at someone’s head. Those are heavy suckers. But absorbing killer levels of iron from a well seasoned skillet? Codswallop.
Look, the way I see it, is if you eat sensibly, you’re fine. Don’t take health supplements with concentrated iron and go easy on the vitamin c, particularly around meal time, as it facilitates the absorption of iron.
As a diabetic, my diet has always been based on three principles; low fat, no sugar, high fibre. Add plenty of fresh vegetables and fruit in to the mix along with a judicious balance of grains and nuts and you’re on a winner. Just because you have a condition with an iron overload doesn’t mean if you eat less iron, it will help you. Your body will still need iron and it will, if you’re eating a good, balanced diet, find it, too. The problem for people like us is getting rid of the excess, once the body has used what it needs.
I like to eat fish, particularly hake and mackerel. Coffee, I’m told, should be avoided but hell, Starbucks notwithstanding, I enjoy a sup of java. At the same time, a good friend of mine turned me on to Japanese Matcha tea that has a high tannin level, is an anti-oxidant and can lessen, if not entirely prevent, the absorption of dietary iron. And apart from anything else, a good cup of Matcha a day can get you involved in some wonderful tea making ritual.
Alcohol? ok, we should all drink less and yes, there is iron in beer and spirits, though a glass of wine is not to be sneezed at. I’m sure this has ruffled a few feathers but I don’t like fad food fascists. Eat sensibly and not in excess, you’ll be fine.
Please don’t take what you’ve read here as the gospel, according to how to behave with hemochromatosis. I’ve got my own problems to deal with and that involves staying healthy by eating as sensibly as I can. All I do is write about it.
