Lactose malabsorption and lactose intolerance: implications for general milk consumption.

B Torún, N W Solomons, F E Viteri

    Archivos Latinoamericanos De Nutricion
    |December 1, 1979
    PubMed
    Summary

    Lactose malabsorption does not always correlate with intolerance, suggesting milk tolerance is often overestimated. Recommended diagnostic methods and continued milk use in children are discussed.

    Area of Science:

    • Nutritional Science
    • Gastroenterology
    • Pediatrics

    Background:

    • Lactose malabsorption and intolerance are common conditions affecting milk consumption.
    • Existing diagnostic methods and assumptions about milk tolerance require critical evaluation.
    • The role of milk in child nutrition, especially during illness, needs clarification.

    Purpose of the Study:

    • To critically evaluate diagnostic methods for lactose malabsorption and intolerance.
    • To assess the correlation between lactose malabsorption and clinical intolerance.
    • To provide recommendations on milk consumption for children, particularly during illness and in supplementation programs.

    Main Methods:

    • Systematic review of 194 publications on lactose malabsorption and intolerance.

    Related Experiment Videos

  • Critical evaluation of diagnostic techniques, including breath hydrogen analysis and double-blind testing.
  • Analysis of evidence regarding milk consumption's impact on child growth and development.

    • Main Results:

    • A poor correlation exists between lactose malabsorption and intolerance to ordinary milk intake.
    • Evidence supports milk consumption for adequate child growth, even with malnutrition and diarrhea.
    • Current data does not support discouraging milk in food supplementation programs.

    Conclusions:

    • Recommended diagnostic improvements include using physiological lactose doses, milk as the vehicle, double-blind intolerance tests, and breath hydrogen analysis for malabsorption.
    • Temporary substitution of non-human milk during severe diarrhea is advised, with gradual reintroduction during recovery; breastfeeding should continue uninterrupted.
    • Milk remains a valuable component in food supplementation programs, with specific considerations outlined.
