Animal protein intake as strongly associated with bone fracture rate for different countries [Abelow, B. et al. Calcif. Tissue Int., 50: 14-18, 1992] and unlike plant proteins, animal protein increases the acid load in the body [1. Wachsman, A. and Bernstein. Lancet, May 4, 1968: 958-959, 1968; Brosnan, J. T. and Brosnan, M. E. In: H. H. Draper (ed.), Advances in Nutritional Research, pp. 77-105. New York: Plenum Press, 1982; Frassetto, L. A., et al. Am. J. Clin. Nutri., 68: 576-583, 1998]
