 Breastfeeding practices have been shown to have a dramatic effect on the incidence of diarrheal disease in poor populations.Studies across a number of developing nations have shown that those who receive exclusive breastfeeding during their first 6 months of life are better protected against infection with diarrheal diseases.One study in Brazil found that non-breastfed infants were 14 times more likely to die from diarrhea than exclusively breastfed infants.
