Lactose tolerance tests were performed on 67 adult Arab villagers. Fifty-four (80.6%) had a low rise in glucose and most had symptoms during the test. Lactose tolerance was not related to age or sex and did not correlate with milk consumption. A high incidence of adult lactose intolerance has been found in all Mediterranean groups studied to date—Greek Cypriots, Jews, and now Arabs.
