https://medlineplus.gov/genetics/condition/lactose-intoleran... "Lactase nonpersistence is most prevalent in people of East Asian descent, with 70 to 100 percent of people affected in these communities." Masai herdsmen are East Africans; so I find that statistic bewildering. "Lactase nonpersistence" means the decline of the production of the enzyme lactase beyond infancy. I don't know whether lactase nonpersistence is equivalent to lactose intolerance. |
