All six micronutrients richly found in ASF, vitamin A, vitamin B12, riboflavin, calcium, iron and zinc play a critical role in the growth and development of children.[1][5] Inadequate stores of these micronutrients, either resulting from inadequate intake or poor absorption, is associated with poor growth, anemias (iron deficiency anemia and macrocytic anemia), rickets, night blindness, impaired cognitive functioning, neuromuscular deficits, diminished work capacity, psychiatric disorders and death.[1] Some of these affects, such as impaired cognitive development from an iron deficiency, are irreversible.girja

The vegan diet is more restricted, and recommendations differ. Poorly planned vegan diets may be low in vitamin B12, calcium, omega-3 fatty acids, vitamin D, iron, zinc, riboflavin (vitamin B2), and iodine.

The Vegan Society and Vegan Outreach recommend that vegans eat foods fortified with B12 or take a supplement. B12 is a bacterial product that cannot be found reliably in plant foods, and is needed for the formation and maturation of red blood cells and the synthesis of DNA, and for normal nerve function; a deficiency can lead to a number of health problems, including megaloblastic anemia.[43] Iodine supplementation may be necessary for vegans in countries where salt is not typically iodized, where it is iodized at low levels, or where, as
