A study has revealed that eating meat can lead to premature puberty in girls. The study was conducted by researchers from University of Bristol and University of Brighton, U. K. It was funded by World Cancer Research Fund.
Experts claim that it is better to avoid diets containing large amount of meat from an early age. As part of this research, 3,000 girls' diets were followed from birth and they were compared when they turned 12.
When these girls reached the age of 12, they were divided into two groups. The first group had started their periods while the second group did. Their diets were also compared when they were aged 3, 7 and 10 years, respectively.

Once again, meat is the target of the hormones and estrogen debate in relation to teenage girls and puberty rates. Unfortunately, this media report falls flat. Hormones are naturally occurring in meat and dairy products, just as they are naturally occurring in people.
A 3-oz. steak from a non-implanted animal has an average of 1.3 nanograms of estrogen, 0.3 nanograms of testosterone and 0.3 nanograms of progesterone. The same-size serving from an implanted animal had an average of 1.9 nanograms of estrogen, 0.6 nanograms of testosterone and 0.5 nanograms of progesterone. Significant? Consider this: a non-pregnant woman produces about 480,000 nanograms of estrogen, 240,000 nanograms of testosterone and 10.1 million nanograms of progesterone daily. (Source: Organic Consumer)
