The answer is probably more about absorption than quantity, say our panel of experts

I’ve been advised to increase the iron in my diet but, as a vegetarian preoccupied with getting sufficient protein, I’m at a loss.

June, by email

Last year, a study by Randox Health found that almost one in three women who attended its UK clinics have an iron deficiency, which is to say that June isn’t alone. Yes, there are good sources that vegetarians can tap into, but we first need to address a few key points: “The heme iron you get from animal sources – red meat and darker poultry, say – is in a form that’s slightly better absorbed than non-heme iron, which is found in the likes of beans, tofu and leafy greens,” says Dominique Ludwig, nutritionist and author of No-Nonsense Nutrition. This is where vitamin C is your friend: “When we eat non-heme iron and vitamin C together, it increases absorption, so it might be a case for having peppers or tomatoes with your tofu.” But there’s another potential hitch: “On a vegetarian diet, some of that iron can be blocked from absorption because of things such as phytates [a plant compound found in whole grains, legumes, etc], or tannins in tea and dairy,” Ludwig adds, so it’s not simply about how much iron you’re getting, but how good your absorption is.
