Does eating non-organic food (milk/meat) cause early puberty in girls? my niece's ped told her mom to give organic as reg milk causes early puberty.

Possibly but...: There is evidence that girls who consume relatively high levels of dairy ; meat have earlier puberty but it is not clear if organic dairy ; meat would affect this; it might be due to the protein increasing growth hormone, but it might also be related to pesticide residues that have estrogen-like effects. I advise eating organic for other reasons- see http://huff.To/1byvjbz ; http://bit.Ly/19xax7e.
