"and one proof is that osteoporosis in more predominant on those countries with high milk consumption, like the US."
You mean lazy people from rich countries with poor diets. It is not proof at all. How balanced a diet is and the amount of exercise children get in their developing years, and later, is much more important.
I clearly stated, "for children".
Yes, dairy products can be unhealthy for adults. The same goes for other animal products. However, there is no doubt that animal products provide nutrition.
What a high rate of osteoporosis in countries with high consumption of milk proves is that consuming milk not only does not provide bioavailable calcium to our bones but in fact removes calcium from the bones. This is true for both adults and children.
Also the extremely potent growth homon present in cow's milk is not good for children and that has been agravated by the introduction of genetically modified growth hormon (rBGH) that is injected to cows every two weeks so they produce more milk. You can get additional information on http://www.ejnet.org/bgh/nogood.html
That's why I don 't drink cows milk and my doughter doesn't either.
I'm not vegan, I'm not against animal products, I consume them also, but not milk, processed foods or non-bio food loaded with poisons and genetically modified.
I live in Europe, so the milk here doesn't have injected hormones. Or at least I think it doesn't - it used to be banned. I remember the US complaining about it because they couldn't import their products. Maybe they do export to us now.
Even if the cows are not inyected with recombinant bobine growth hormone (rBGH) it still has "natural" BGH which is meant to make the calf to grow from 30kg to over 140kg in only 4 months. It is believed that BGH is not active in humans but this study sugest that there is a metabolic activity in humans of a fragment of BGH Metabolic Effects in Children of a 37 Amino Acid Fragment of Bovine Growth Hormone 1!. In other words, european milk cotains cows growth homones that are affecting our children, well not mine because I don't give her milk and gets all the calcium she needs from chickpeas, green leaf vegetables, brocolli and almonds.
