I didn't become anemic because of my diet, but for other reasons (age-related women's problems, if you know what I mean). But many of the foods rich in iron are foods that just don't appeal to me (in general, but especially now), in large part because they leave me bloated and uncomfortable. Beans and lentils, kale, anything wheat-based... so many others... And stuff I like which should be ok, I've been warned against because of the calcium content, like broccoli. Broccoli is delicious! But also has enough calcium potentially to interfere with the absorption of iron.
I get that I have to suck it up, but it's an annoyance,and look at that! Annoyance is also the title of this topic!
I love spaghetti with tomato sauce. It's my "I don't feel like cooking" comfort food, and is one of dishes for which I will suffer the bloating. Cast iron pan spaghetti it is! (no parmesan, though. Darn calcium!)
