Calcium in Evolutionary Perspective


Calcium in Evolutionary Perspective

S B Eaton et al. Am J Clin Nutr.


The nutritional requirements of contemporary humans were almost certainly established over eons of evolutionary experience and the best available evidence indicates that this evolution occurred in a high-calcium nutritional environment. The exercise and dietary patterns of humans living at the end of the Stone Age can be considered natural paradigms: calcium intake was twice that for contemporary humans and requirements for physical exertion were also greater than at present. Bony remains from that period suggest that Stone Agers developed a greater peak bone mass and experienced less age-related bone loss than do humans in the 20th Century.
