A lot of it in the height increase outside North America and Western Europe comes from better nutrition. Borderline malnourishment in childhood and adolescence effects adult height (among many other things.) Go to a country that developed very quickly, and you will notice a marked height difference in generations. South Koreans in their 20’s and 30’s, who grew up when the county was a leading modern industrial economy, tower over their older counterparts who grew up in the 1950’s, when Korea was a recently-war-torn agrarian backwater.
