Until the 20th century, the average age of puberty for girls was 16 or 17 years old. Now, we’re seeing significant numbers of girls starting to grow breasts before they’re 8. The change has been so dramatic that the medical profession has had to keep changing its standards for what’s currently pathological. The question is why.

Is it just fiction that the increase in meat consumption has something to do with it?

It appears to be fact. Based on Harvard data, “Girls who consumed more…animal protein and less vegetable protein” started their periods earlier. And it may not just be the hormone content in milk, meat, and eggs.

A study of Korean children found that seafood and processed meat seemed to be the main culprits, and they think it may be the endocrine-disrupting industrial chemicals that build up in the meat—fish in particular—like the dioxins and PCBs, which may be what’s doing it.

  1. imagine how a plant-based america would change the whole birth control debate! i wonder how much teenage pregnancy would be reduced?

  2. Ive heard that environmental pollutants are much less in colder water, Alaskan Salmon, because the cold water is much dense and thus pollutants descend faster….but what about migrating fish carrying the contaminant?

  4. I guess this explains why I got my period at age 10, a couple of years younger than my mother, and even younger than my older sister. I ate a LOT of animal products as a kid. I hope to pass on what I am now learning to my future kids, and until then, to everyone I know. I was too young for puberty, I hadn’t even learned about it in school, yet. I would have rather had more childhood bliss, than monthly cramping. I even had to go to the doctor frequently, because of my irregular cycle. That’s not the ideal way to become a woman.
