METHODS: Descriptive study, based on an integrative review of literature from PubMed and LILACS data published between January 1992 and August 2011. The keywords \"breastfeeding AND diarrhea\" was searched in Portuguese, English and Spanish in PubMed and LILACS. The guiding question was: \"What was knowledge produced about breast feeding and prevention of diarrhea in children under 2 years between 1992 and 2011 in studies conducted in Brazil?\"
RESULTS: We selected 11 studies that showed the importance of breast feeding in the prevention and protection against diarrhea in children under 6 months, especially among children in exclusive breastfeeding.
CONCLUSIONS: Public health policies should be directed to the context of each locality, in order to reduce the problems that involve the early weaning.
