Here's the osteoperosis studies...
Osteoperosis studies I looked up here and there...
1.) A 1994 report in the American Journal of Clinical Nutrition showed that when animal proteins were eliminated from the diet, calcium losses were cut in half. (Remer T, Manz F. Estimation of the renal net acid excretion by adults consuming diets containing variable amounts of protein. Am J Clin Nutr 1994;59:1356-61.)
2.) A 1992 review of fracture rates in many different countries showed that populations with the lowest calcium intakes had far fewer fractures than those with much higher intakes. For example, South African blacks had a very low average daily calcium intake-only 196 milligrams-yet their afracture incidence was only 6.8 per 100,000 person-years, far below that of either black or white Americans, whose incidence rates were 60.4 and 118.3 per 100,000 person-years, respectively. (Abelow BJ, Holford TR, Insogna KL. Cross-cultural association between dietary animal protein and hip fracture: a hypothesis. Calif Tissue Int 1992;50:14-8.)
3.) The Harvard Nurses' Health Study of 77,761 women, aged 34 to 59 followed for 12 years, found that those who drank three or more glasses of milk per day had no reduction in the risk of hip or arm fractures compared to those who drank little or no milk, even after adjustment for weight, menopausal status, smoking, and alcohol use. In fact, the fracture rates were slightly, but significantly, higher for those who consumed this much milk, compared to those who drank little or no milk. (10.
