  1. Adult hypolactasia, milk consumption, and age-specific fertility.

    Article - En anglais

    Beta-galactosidase (lactase) allows the digestion of lactose as its component sugars, galactose and glucose.

    Considerable variation exists worldwide in the prevalence of adults who lose the ability to digest lactose after infancy (hypolactasia) as well as in the amount of milk products they consume.

    Clearly, those populations in which hypolactasia is infrequent and milk consumption high will have greater dietary exposure to galactose.

    Because there is clinical and experimental evidence that galactose may be toxic to ovarian germ cells, the authors sought to determine whether age-specific fertility rates in various countries correlate with the prevalence of adult hypolactasia and per capita milk consumption by analysis of published data on these variables.
