Age dependency of the lactase persistence and lactase restriction phenotypes among children in Sri Lanka and Britain.

All neonates are born with intestinal lactase activity. In most of them the intestinal lactase activity is lost during childhood (lactase restriction phenotype). In a minority of children normal intestinal lactase activity is retained (lactase persistence phenotype).
