Good idea. One can do it by e-mail, or visit the archive site at:

Studies that correlated calcium loss with high protein diets used isolated,
fractionated animo acids from milk or eggs.(1) Dr. Herta Spencer, of the VA
Hospital in Hines, IL shows that when protein is given as meat, subjects do
not show any increase in calcium excreted, or any significant change in
serum calcium, even over a long period.(2) Other investigators found that a
high protein intake increased calcium absorption when dietary calcium was
adequate or high, but not when calcium intake was a low 500 mg per day.(3)
