IntroductionThe level of iodine in breast milk may be inadequate and compromise the health of this, both due to excess and lack, some population groups remain deficient because of the low consumption of iodate salt, because there is an increase in consumption of other sources of iodine, such as supplements and fortified foods.ObjectiveTo evaluate the effect of the consumption of fortified foods and nutritional supplements with iodine on maternal milk levels.MethodologySystematic review based on the Prism method, using the descriptors provided by DeCS. The reading, selection and analysis of the methodological quality of the articles was done by two researchers independently.ResultsFrom 346 abstracts, 6 were eligible. The median iodination range between the studies ranged from 75 to 600 µg in supplements and 150 and 225 µg in fortified foods with effect on increased iodine concentration of breastmilk (BMIC), achieving the adequacy of the median BMIC in 4 of the 6 studies.ConclusionIodine ingestion through supplements or fortified foods results in improved iodine levels in breast milk.© 2021 Machamba AAL et al.
