It is often recommended for the elderly or people withosteoporosis to consume food supplements based on calcium and vitamin D. Strengthening the bones, it would lower the risk of fractures. Several previous studies had already had mixed results on this subject. In order to provide new data, Chinese researchers from Tianjin Hospital carried out a meta-analysis of 33 clinical trials comparing the use of these supplements (calcium, vitamin D or both) with a placebo or lack of treatment. Their study appeared in the Journal of the American Medical Association.
Pay attention to your diet
A total of 51,145 adults over the age of 50 participated in these clinical trials. No significant difference was observed for calcium and/or vitamin D intake in relation to the number of fractures. These observations were made regardless of the doses taken, the sex of the patient or his history of fractures. This study therefore does not support the consumption of calcium or vitamin D as a means of preventing fractures. This goes in the direction of two previous British studies who had noticed an increase in bone density of only 1 to 2% after 5 years! This increase was, moreover, unlikely to significantly reduce the risk of fractures… According to the doctors, A balanced diet should be enough to keep our bones healthy.
