Iron, calcium among essential minerals for mother and baby

Iron, calcium among essential minerals for mother and baby.jpg
Pregnant and nursing mothers have unique nutritional requirements to help feed the needs of themselves and their babies.

It should come as no surprise that the maternal nutritional status of essential nutrients can affect the mother and pregnancy outcomes. With some nutrients, maternal consumption can also have a postnatal effect on the infant. Thus, adequate maternal dietary consumption is key to providing optimal infant nutrition and subsequent development and growth.

During pregnancy, the National Institutes of Health (NIH) notes daily iron requirements are higher than that of a comparable non-pregnant female. The primary reason for this increase in iron needs is to support the growth and oxygenation of the maternal support tissues and the growing fetal tissues, per an Institute of Medicine (IOM) publication. In a recent analysis of NHANES data sets, iron deficiency was prevalent in 16.3% of pregnant females, and iron deficiency anemia was found 2.6% of pregnant females in the U.S.1 In China, 19.8% of women had iron deficiency and 13.9% had iron deficiency anemia.2 Iron deficiency in pregnant women can increase the risk for preeclampsia and fetal membrane rupture.3

Calcium is essential for many functions in the body but is primarily known for mineralization of the bones. A review article on calcium in pregnancy indicated the maternal body undergoes several changes to supply the growing fetus sufficient calcium for its needs.4 The review noted chronic low calcium intake can increase the risk for gestational complications, such as preeclampsia and preterm delivery. The fetal calcium needs are prioritized over the maternal needs. The mother will supply the needs for the fetal tissues through increasing maternal intestinal absorptive capability from dietary sources of calcium, and by bone mineral resorption from her skeleton if insufficient calcium is absorbed from dietary sources. This bone remodeling can be short term or—depending on intake and level of bone remodeling—can lead to a more permanent condition of osteoporosis.
