Vitamin deficiencies are generally rare in exclusively breastfed infants but when the mothers diets are deficient their infants may have low intakes of certain vitamins such as vitamin A riboflavin vitamin B6 and vitamin B12. There was a positive correlation between zinc.
For example zinc is required for several enzymatic functions including cell and tissue growth cell division embryogenesis fetal growth and development as. Pregnant women need more zinc than usual because the. Children on restricted diets and babies who are exclusively breastfed longer than 6 months may also experience zinc deficiency.
Lessened appetite lowered immune function limited activity growth faltering. Only a few dozen cases have been reported. This paper describes a breast-fed preterm infant who developed profound zinc deficiency and low plasmacopperconcentrations.
All infants should be offered complementary foods that contain zinc including meat poultry oysters spinach nuts beans and mushrooms. Zinc deficiency can happen in people who have problems absorbing nutrients for example older people and those who have some gut diseases. Thus there seems little question that zinc deficiency occurs in young infants including those who are breastfed but the circumstances are not yet well characterized.
We performed a zinc supplementation trial in Paris France to find out whether such growth faltering is due to nutritional zinc deficiency. There was a higher proportion of maternal zinc deficiency in zinc-deficient infants than those without zinc deficiency 667 vs 162 p002. Pregnant or breastfeeding mothers are prone to zinc deficiency as babies get zinc only from their mother leaving the mothers body with lower amounts of zinc.
Good sources of zinc include meat especially red meat and yogurt. A vegetarian diet can lead to zinc deficiency as lots of zinc is obtained from meat and seafood. In most cases healthy full-term exclusively breastfed babies have sufficient iron stores for at least 6 months.
Causes Of Zinc Deficiency In Humans. Zinc is called an essential trace element. Breastfed being a self-limiting and benign condi-tion caused by defective mammary zinc secretion known as transient symptomatic zinc deficiency TSZD3 4 Zinc deficiency is rare but some studies have reported that the acquired deficit including subclinical deficiencies and asymptomatic indi-viduals can affects up to 17 of the population worldwide particularly in.
The acquired types of zinc deficiency could be caused by insufficient intake such as in cases of low milk zinc levels in breastfeeding women increased loss as in gastrointestinal illnesses recalcitrant diarrhea intestinal fistulas or urinary losses renal diseases malabsorption as in case of chronic inflammatory bowel diseases and increased requirement such as in preterm.

They are characterized by zinc deficiency and a triad of periorificial and acral dermatitis alopecia and diarrhea. It is attributable to the decreased zinc content of human milk as compared to cows milk and the increased demand of zinc in rapidly thriving preterm infants.
A mutation in the gene for a zinc transporter protein may account for abnormally low milk zinc concentrations associated with severe zinc deficiency in breastfed infants. Type II hypozincemia of infancy is a rare hereditary zinc deficiency occurring in infants while exclusively on breast feeding. Nutrient deficiencies even in minute amounts might have detrimental effects on both pregnancy and lactation.
Infants with zinc deficiency should be supplemented with 2mgkg of zinc sulfate daily and they may continue to breastfeed. Exclusively breastfed babies who are born healthy and at full term are at very low risk only 3 in the first 6 months of being iron deficient. We conclude that nutritional zinc deficiency is a frequently misdiagnosed problem in thriving fully breast-fed preterm babies.

The people at the highest risk of zinc deficiency in the United States are infants who are breastfeeding and older adults. Zinc deficiency in breast-fed full-term infants is sometimes caused by congenital acrodermatitis enteropathica OMIM201100 which is caused by a mutation in the SLC39A4ZIP4 gene18192021 and.
Breastfed infants with zinc deficiency had significantly lower maternal zinc concentrations compared with those without zinc deficiency. Giving supplemental iron to a baby under 6 months of age may be harmful. Healthy full-term breastfed babies do not need additional zinc past what they get from breastmilk and after 6-8 months from complementary foods.
Similarly the estimated preventive effect of zinc supplementation on pneumonia is similar to that estimated for breastfeeding. Some medicines can also increase the loss of zinc through urine. Among breastfed infants growth faltering in comparison with reference growth curves is common in both developing and developed countries.
