I Heard That Spinach Isn't Actually That Full Of Iron, Is That True?

In popular folklore, spinach is a rich source of iron. In reality, a 60 gram serving of boiled spinach contains around 1.9 mg of iron (slightly more when eaten raw). A good many green vegetables contain less than 1 mg of iron for an equivalent serving. Hence spinach does contain a relatively high level of iron for a vegetable, but its consumption does not have special health connotations as folklore might suggest.

The myth about spinach and its high iron content may have first been propagated by Dr. E. von Wolf in 1870, because a misplaced decimal point in his publication led to an iron-content figure that was ten times too high. In 1937, German chemists reinvestigated this "miracle vegetable" and corrected the mistake. It was described by T.J. Hamblin in British Medical Journal, December 1981.

Spinach still has a large nutritional value, especially when fresh, steamed, or quickly boiled. It is a rich source of Vitamin A, Vitamin C, Vitamin E and several vital antioxidants. Recently, opioid peptides called rubiscolins have also been found in spinach. It is a source of folic acid, and this vitamin was first purified from spinach. To benefit from the folate in spinach, it is better to steam it than to boil it. Boiling spinach for four minutes can halve the level of folate.

It is best if you seek facts from literature or a certified nutritionists. Factual information is best used instead of just asking around. But as far as I have read spinach is loaded with all types of good stuff. The darker the leafy green vegetable the more vitamins it packs.
