Fab already gave us some source material on this subject but I promised to do research so here it is.
"Preventing Osteoporosis" by DR. Kenneth Cooper page 117
"Various studies have shown that a diet heavy in animal protein may encourage bone loss. The reason for this is that animal proteins are rich in sulfur-containing amino acids. These acids promote loss of calcium through the urine. Also, retention of acid in the system is thought to promote bone resorption, or destruction of bone tissue. In other words, too much animal protein may help create a negative calcium balance in the body and a net bone loss associated with osteoporosis."
"Stronger Bones" Prevention magazine by James Fleet Ph.D Director of Nutritional Studys University of North Carolina
"It's an accepted fact that eating too much protein leaches calcium from the body, jeopardizing bone health. Eating excess protein produces an acid load in the body that must be countered by chemicals released from bone tissue . In the process, calcium is liberated and washed away in the urine, contributing to bone thinning. Eating twice the RDA for protein boosts daily calcium requirements by 250 milligrams and could contribute to osteoporosis."
"Strong Women Strong Bones by Miriam E. Nelson, Ph.D School of Nutrition Science, Tufts University
"Though adequate protein consumption is essential for strong bones, extremely high protein levels increase urinary excretion of calcium. Problems can develop when people follow unbalanced high-protein diets, or when they add protein supplements such as powders and enriched drinks to a diet that already has plenty of protein."
"The Osteoporosis Handbook" Sydney Bonnick M.D. Center for Research on Womens Health, Texas Womans University
"Excessive protein in the diet can increase the loss of calcium in the urine. Every time you double the amount of protein you eat the amount of calcium you lose in your urine increases by 50%. The recommendation for protein intake for a woman is 44 to 50 g per day. Studies have clearly linked dietary protein consumption to the risk of hip fractures."
I checked 4 other books and they all listed high protein as a contributeing factor for osteoporisis.

NM,
All good info to keep in mind, and a good argument to opt for a healthy, balanced diet.
I keep reading the scientists really can't comment about the long term effects of people following high protein diets like Atkins since they have just become so popular. It takes time for bones to deteriorate, especially if the subjects are younger, stronger, or healthier. But it is a fact that as women get older, our bodies love to chomp away on our bones, and if they are damanged already from years of high-protein diet fads--who knows how bad it will get.
They've already "tweeked" Atkins once--telling the people who follow their program to reduce the amount of saturated fat in what once was a saturated-fat "free-for-all" diet. Can the protein vs bone loss argument be somewhere down the road? As an old lady, I can't afford to take that chance with what bone matter I have left after years of abuse so far.
Let's hope this isn't like the Fen-Fen or Ephedra fiasco where they close the gate after the horses have escaped.

Interesting.... I'll have to look into this more. I'd love to know the molecular and/or chemical specifics :))
Cheers,
Luna ;))
