Kefir, a fermented milk product, "has the potential to be utilized as an alternative treatment for postmenopausal osteoporosis". That is according to research published by Chen, et al. in the latest issue of Osteoporosis International. Kefir's amazing bone-health-promoting effects come not only from its high calcium content but also from its abundance of bio-active proteins. When milk is cultured with yeast and bacteria unique peptides are formed that enhance calcium absorption, boost the immune system, prevent blood clots, and ward off bacterial infections. Adding kefir to your daily diet can be a great boost to your overall health.
By studying ovariectomized rats, Chen and colleagues determined that kefir, given daily over a 12 week period not only reduced CTX (a bone resorption marker indicative of osteoclast bone resorbing activity) but also actually prevented bone loss. The kefir improved bone mineral density as well as trabecular strength properties as measured through micro-CT scanning.
The authors concluded that kefir "may have the potential to prevent or treat osteoporosis in humans resulting from estrogen deficiency."
