Effect of milk-containing diets on the severity and duration of childhood diarrhea.

Individual components of milk from humans and other mammalian species may influence the severity, duration, and nutritional outcome of childhood diarrhea in different ways. Nonetheless, empirical data from clinical trials can be used to assess children's responses to specific milk-containing diets. Factors modifying the response to milk include its source, amount, frequency of feeding, type of processing, and accompanying foods, as well as the type and severity of enteric infection and specific characteristics of the host. Whereas breast-fed infants have less severe diarrhea when breast milk is continued rather than interrupted, infants and children fed with non-human milks tend to have more severe illness than those receiving milk-free or lactose-limited formulas or milk-cereal mixtures. Fermentation of milk may reduce the severity of lactose malabsorption, but additional information regarding the efficacy of yogurt in acute, childhood diarrhea is still needed.
