The Iron Dilemma: Factors To Consider
Anemia affects around 10% of American seniors, and that number jumps to 34–39% if there’s a comorbidity such as diabetes, hypertension, or hypercholesterolemia, which in turn climbs with increasing age or with other chronic conditions:
So, what can we do about it?
Get iron yes, but how?
We’d be remiss not to say: yes, do of course make sure you get plenty of iron.
Most people know that red meats, which are terrible for the heart and for cancer risk, are good sources of iron.
Well, good insofar as they provide plenty of it! They’re bad for other reasons.
❝Studies consistently show that consumption of red meat has been contributory to a multitude of chronic conditions such as diabetes, CVD, and malignancies.
There are various emerging reasons that strengthen this link-from the basic constituents of red meat like the heme iron component, the metabolic reactions that take place after consumption, and finally to the methods used to cook it.
The causative links show that even occasional use raises the risk of T2DM.❞

To heme or not to heme
Did you catch that in the middle there, about the heme iron component?
Dietary iron is broadly divided into two kinds: heme, and non-heme.
- Heme iron comes from animals
- Non-heme iron comes from plants
Bad news for vegans: non-heme iron is not so easily absorbed as heme iron.
This means that if you’re just eating plants, the RDA may be significantly lowballing the amount actually required. As a rule, about 1.8x more iron may be needed for vegans, to compensate for it being less easily absorbed.
Why this happens: it’s because of the phytic acid / phytate in the plants that contain the iron, blocking its absorption.
Good news for vegans: however, taking iron with vitamin C increases its absorption rate by about 5x better absorption, and several other side-along nutrients do similarly, including allium (from garlic), carotenoids (from many colorful plants), and fermented foods.
Why this happens: it’s because they bind with similar sites as phytic acid, without causing the same effect. To make a metaphor: these foods steal phytic acid’s parking space, so phytic acid can’t do its iron-blocking thing.
By happy coincidence, today’s featured recipe has all of these things in, by the way (vitamin C, allium, carotenoids, and fermented foods), and the star ingredient (fava beans) is a rich source of iron.
What are good sources of iron, then?
In the category of plants:
- Beans (pick your favorites / eat a variety)
- Lentils (pick your favorites / eat a variety)
- Greens (especially dark leafy greens)
- Apricots (you can get these dried, for convenience!)
- Dark chocolate (5mg per 1oz square!)*
*Ok, technically dark chocolate is not a plant; cacao is a plant; dark chocolate is usually plant-based, though, as there is no reason to add milk.
In the category of dairy products:
That’s not a publication error; dairy products are just not great for iron. Cheeses are more nutrient-dense than milk, and have less than 0.5mg per oz, in other words, the top dairy product has around 10x less iron than dark chocolate, which came in 5th place and let’s face it, we were doing broad categories there. If we listed all the beans, lentils, greens, etc it’d be a much longer list.
Eggs, which are sometimes considered under the category of dairy by virtue of not being an animal (yet!) but an animal product, have around 1mg per egg, by the way, so considering eggs are nearer 2oz, that’s not much better than the cheese.
“But what about if…”
The above is good science and general good advice for most people. That said, some people may have conditions that preclude the foods we recommended, or have other considerations, and so things may be different. Anemia can sometimes be caused by things that can’t be fixed by diet (beyond the scope of today’s article; another time, perhaps), but for example, if you have leukemia then definitely discuss things with your doctors first. Other illnesses, and some medications, can also have troublesome effects that can contribute to anemia. Again, we can offer very good general information here, but we don’t know your medical history, and our standard legal/medical disclaimer applies as always.
