According to the NY Times:
Calcium, eaten in foods or taken as supplements, has little or no effect on bone density or the risk of fracture in people over 50, according to two large reviews of studies in BMJ.
Presumably that’s the British Medical Journal. Before dismissing the finding as just another of these reversals of beliefs so ingrained as to seem like common sense, do know that the studies together had over 50,000 participants. And the BMJ is very highly regarded.
I can’t decide quite why I’m feeling a bit irritated. Maybe one or many of these:
– The chances of a reversal of this showing up within a year, given how these hot health news stories get worked out.
– The sanctimonious manner in which one can be asked by anyone taking health data, “And calcium supplements”?
– The number of times I’ve checked on the calcium content of foods.
– The times I’ve bought prime cost yoghurt because of its high calcium content.
