Genetic and environmental factors associated with lactose digestion in African populations.

Abstract excerpt

Impaired lactose digestion, primarily resulting from lactase non-persistence (LNP), is widely observed across African and non-African populations; however, its prevalence differs according to genetic background and dietary practices. Although numerous pastoralist cultures in Africa have independently developed lactase persistence (LP), a sizable portion of the population experiences primary or secondary lactose...
