Iron content of spinach – myth and truth

For a long time it was believed that spinach contains around 35 milligrams of iron per 100 grams. Then it turned out that this value agreed with – at least not for fresh spinach. The extremely high iron content was calculated in 1890 for spinach powder and later on may be in error on fresh spinach to transfer – when and how the error came about exactly, is controversial.

Nevertheless, spinach is not an ideal source of iron. On the one hand, the body’s herbal iron is not can use as well as animal. On the other hand, spinach contains oxalic acid, which binds to the iron it contains and the body is so complicated, the mineral.

Therefore, it is advisable to spinach to eat in conjunction with foods, which reduces the effect of the oxalic acid.
