Introduction: This study aims at systematically reviewing the observational and interventional studies on the association of maternal macro- and micronutrient intake with breast milk content. Methods: We systematically searched the Medline via PubMed, Scopus, and ISI Web of Knowledge till October 2016 with the following search strategy: ( human milk OR breast milk OR breast milk composition OR human breast milk composition OR composition breast milk OR mother milk OR human breast milk )AND ( maternal diet OR maternal nutrition ). We also searched Google scholar for increasing the sensitivity of our search. The search was not limited to title and abstract due to the possibility that the desired outcome might have been considered a secondary aim. We excluded conference papers, editorials, letters, commentary, short survey, and notes. The search was refined to English language, and we did not consider any time limitation. To increase the sensitivity and to select more studies, the reference list of the published studies was checked as well. Results: This review included 59 observational and 43 interventional studies on maternal diet related to breast milk composition. Different studies determined the associations and effects of some maternal dietary intake of micro and macronutrients and its reflection in human milk. Conclusion: Maternal dietary intake, particularly fatty acids, and some micronutrients, including fat soluble vitamins, vitamin B1, and vitamin C, was related to their content in breast milk composition.
