Why puberty starts earlier nowadays?

Question

I’ve seen a study which found that the age of puberty (especially female puberty) is dropping rapidly. In 1860 it started around 16.8 and in 2010 it was 10.8. Why is that? Is there any explanation?

There’s a few factors but that’s a major one. Also our livestock being pumped full of hormones works it’s way into our foods and some highly processed foods have unexpected impacts on health. Also your caloric intake has an impact on how fast you age. People and animals that generally eat less age slower and live longer. But if you’re looking for one single reason I’d go with “Change in diet”
