Dear fellow researchers,
Does anyone hold any useful information (or possibly a reasonable estimate) on the incidence rates (by age groups, if possible) of lactose intolerance and/or lactase deficiency in US?
The report that was shared by @Safa Aouinti, it is varied among descendants of various population:
"African American, Hispanic, Asian, and American Indian
populations Lactose Intolerance rates may be 50 percent higher in late childhood and adulthood."
