A tiny segment of the population preaches to another segment of the population that they have osteoporosis or some bone issue and that since bones contain calcium means that they should ingest more calcium to correct their problem.
But Ca is ubiquitous and the problem is not in not getting enough Ca, rather the poisoning of the osteoclast/osteoblast equilibruim by things in diet like all the junk we've previously discussed at length.
Simple minds like simple answers, like, eat more Ca and your problems will go away. Lies by themselves have no consequences, it requires the receiver to believe in the lie, to give it life in their mind. It is ying energy, to be submissive to receive and give life to lies.
