Interesting information from the Keefe Clinic:
The evidence continues to pour in that eating plenty of fruits and vegetables is good for your health. In this case, researchers found that both young and old age groups had improvements in bone mineral status when they ate a lot of fruits and vegetables.
Specifically, boys and girls aged 16-18 years and women aged 60-83 years had significant positive associations between spine bone mineral content and fruit intake. In boys, the association was true for neck bone mineral content as well.
Among women aged 60-83 years, a significant positive association was also found between spine bone mineral content and fruit intake. The results found that if fruit intake doubled, it would result in a 5 percent increment in spine bone mineral content.
Previous studies have also found associations between fruit and vegetable intake and positive measures of bone health.
It is not yet known how fruits and vegetables may affect the bones, though some suggest it may be the alkalizing effect of fruit and vegetable consumption on acid-base balance. Other possible mechanisms include the dietary effects of vitamin K, phytoestrogens and other unidentified dietary components they contain.
