Calories in Spinach, baby
The 'iron superfood' reputation that started with a 19th-century decimal error
27 kcal
What makes spinach so powerful?
Spinach's legendary iron reputation traces back to a mistake: a 19th-century data point got copied with a misplaced decimal point, making spinach look like it had ten times more iron than it actually does — a myth so persistent it later inspired Popeye's spinach-fueled strength. Spinach genuinely is a solid plant source of iron, just not a freakish one, and crucially, its iron is the "non-heme" plant form, which the body absorbs far less efficiently than the iron in meat — unless you pair it with vitamin C. Spinach is also high in oxalates, compounds that bind calcium and further reduce how much of spinach's own calcium and iron you actually absorb.
The decimal point myth
A 19th-century data error inflated spinach's iron reputation tenfold — the myth still persists today.
Iron needs a partner
Spinach's plant-based iron absorbs poorly alone; vitamin C dramatically improves uptake.
Oxalates work against it
Spinach's own oxalates bind some of its calcium and iron, limiting how much you actually absorb.
💡 When & how to use it
Pair spinach with a vitamin C source — lemon, tomato, citrus — to meaningfully boost iron absorption. Light cooking actually reduces oxalate content compared to eating it raw, so cooked spinach can deliver more usable calcium and iron than a raw salad.
