Diet and social stress factors the major culprits in girls early puberty
Many young girls are staring puberty before they are emotionally ready for the change. Around the 1900s, in the US the average menarche –when a girl gets her first period- was about 14. After the World War 2 the age of puberty was typically at 11-12 years. Especially since the 1980s has the age of puberty fallen and for increasing number of girls is now gradually declined to 7-8. Ever since the turn of the century many environmental, societal and dietary changes are occurring and by the age of 7 girls are starting to develop breasts and the onset of menstruation.
