Conjugated linoleic acid inhibits osteoclast differentiation
We have unquestionably moved from the “milk it does a body good” dogma of bone health to one of inflammation driven bone loss. Given that unhealthy lifestyles lead to inflammation, it is no big surprise that osteoporosis is becoming a larger and larger issue in Western cultures. It has less to do with dairy and calcium intake (and given that animal proteins like dairy are more inflammatory…) and more to do with lowering oxidative stress and inflammation.
This is one of the reasons why we have seen fish oils help with bone–it has no direct effect on bone, rather, it lowers inflammation and stops the loss of bone.
