There is also a little iron in bananas: 0. 3 to 0. 5 mg per 100 g of fruit. This tracement intervenes in the hematopoyesis process, that is, in the production of hemoglobin, as well as in the synthesis of thyroid hormones. The lack of this micronutrient immediately affects the composition of the blood: the person can develop anemia.
