Zinc (Zn) is an essential element of nutrition. It is present in many foods.
The daily needs of Zn are 8 to 15 mg (Hall Moran 2010) and depend on the daily intake of phytates. In nursing mothers they are 11 mg for low intakes of phytate (≤ 330 mg/day) and 14 mg/day for high intakes (≥ 990 mg/day) of phytate (Haase 2020).
There are millions of people in the world with Zn deficiency.
It is used as a treatment in Wilson’s disease and acrodermatitis enteropathica.
Zn intervenes in the process of regulation of lactation (Lee 2016).
Pasteurization of breast milk does not affect the concentration of Zn or other trace elements (Mohd-Taufek 2016).
The mean Zn concentration in breast milk is 4 to 16 mg/L (Picciano 1976, Hannan 2005, Dórea 2012) and is independent of plasma levels and daily maternal intake (Krebs 1995, Chierici 1999, Hannan 2009).
The intestinal absorption of zinc almost doubles during pregnancy and lactation (Fung 1997).
Infant zinc levels depend on zinc levels in breast milk (Dumrongwongsiri 2015)
With a varied and balanced diet, mineral supplements are not necessary. Excess ingestion of zinc can lead to gastric, intestinal and pancytopenia problems (Irving 2003).
