Certain lifestyle and nutritional factors are known to
reduce the risk of osteoporosis. Among the nutritional factors, dried plums or
prunes (Prunus domestica L.) are the most
effective fruits in both preventing and reversing bone loss.
A clinical study published in the
British Journal of Nutrition in 2011 examined the extent to
which dried plums reverse bone loss in osteopenic postmenopausal women. In the
study, 160 women who were 1–10 years postmenopausal and not on hormone
replacement therapy or any other prescribed medication known to influence bone
metabolism were randomly assigned to one of the two treatment groups: dried
plums (100 g/d) or dried apples (comparative control). (One hundred grams
of dried plums per day equals about 10 dried plums.) Participants received 500 mg
calcium plus 400 IU vitamin D daily.
Dried plums significantly increased the BMD of the ulna and spine in
comparison with dried apples. In comparison with corresponding baseline values,
only dried plums significantly decreased serum levels of bone turnover markers,
including bone-specific alkaline phosphatase and tartrate-resistant acid
phosphatase-5b. The findings of this study confirmed that dried plums improve
BMD in postmenopausal women, in part due to suppressing the rate of bone
turnover.
