High calcium intake may not help prevent fractures
For years, getting a lot of calcium has been portrayed as one of the best things you could do to prevent osteoporosis and related bone fractures. Small study results supported this view. But when researchers started to crunch the data from large, prospective studies that followed people for many years, the benefits weren’t so clear-cut, reports the March 2008 issue of the Harvard Health Letter.
The ambiguity led to trials to test what effect calcium might have on fracture rates. Two studies showed that calcium didn’t prevent fractures—even when taken in combination with vitamin D. Another study showed that postmenopausal women who took a calcium-vitamin D combination were no less likely to break their hip than women who took a placebo pill.
