While the global average for lactose intolerance exceeds 65%, recent data suggests a stark contrast in Sweden. Estimates indicate that a small fraction, likely between 4% and 10% of the Swedish population, experiences noticeable symptoms of lactose intolerance, which is exceptionally low on a global scale.

Approximately two-thirds of the world's adult population is lactose intolerant. This variation explains why there is no single answer to the query, 'Which race do they drink milk?,' and instead points to a complex genetic history rooted in human evolution and cultural practices.
