Nutrition profile

100 g of raw spinach contains roughly 23 kcal, yet it is dense in vitamin K, folate and beta-carotene (a precursor of vitamin A). The values are approximate averages. Spinach shrinks a great deal when cooked; a pan of raw leaves turns into a few servings of cooked vegetable, which makes it easier to take in more nutrients from the same amount.

What to know about iron

Spinach contains iron, but it is plant-based (non-haem) iron, absorbed less readily by the body than iron from animal sources. A compound in spinach called oxalate limits absorption somewhat as well. One practical approach is to add a source of vitamin C to a meal containing spinach: a squeeze of lemon, or tomatoes alongside it, can support the absorption of plant iron.

Storage and food safety

Fresh spinach wilts quickly; it can be kept unwashed in a perforated bag with a slightly damp piece of kitchen paper in the fridge for a few days, then washed thoroughly just before use. Soil residue is common on leafy vegetables, so the washing step should not be skipped. A cooked spinach dish should not be left standing at room temperature; refrigerate it within two hours and eat it within a few days.
