Spinach is a moderate source (10–19% of DV) of the B vitamins, riboflavin and vitamin B 6, vitamin E, potassium, iron, magnesium, and dietary fiber (table). Although spinach contains moderate amounts of iron and calcium, it also contains oxalates, which may inhibit absorption of calcium and iron in the stomach and small intestine. Cooked ...
Raw spinach is high in oxalates, which bind to minerals like calcium and prevent the body from absorbing them, says Stefanski. Oxalates can increase the risk of kidney stones in some people, per ...

As some of its names signify, it has similar flavour and texture properties to spinach, and is cooked like spinach. Like spinach, it contains oxalates ; its medium to low levels of oxalates need to be removed by blanching the leaves in hot water [ 13 ] for one minute, then rinsing in cold water before cooking.
Members of the spinach family and the brassicas (cabbage, broccoli, brussels sprouts) are high in oxalates, as are sorrel and umbellifers like parsley. [37] The leaves and stems of all species of the genus Chenopodium and related genera of the family Amaranthaceae, which includes quinoa, contain high levels of oxalic acid. [38]
However, spinach and Swiss chard contain oxalates that bind iron, making them almost entirely unavailable for absorption. [citation needed] Iron from non-heme sources is more readily absorbed if consumed with foods that contain either heme-bound iron or vitamin C. This is due to a hypothesized "meat factor" which enhances iron absorption. [35]
