Findings from a new study suggest that natural pigments found in plants may help protect against bone loss in older men and women. Researchers funded by the Agricultural Research Service (ARS) reported the findings in a paper published online by The American Journal of Clinical Nutrition.
The study was led by epidemiologist Katherine Tucker with the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University in Boston, Mass. Tucker directs the HNRCA's Dietary Assessment and Epidemiology Research Program.
Other studies have consistently shown that fruit and vegetable intake is good for bones. Biological antioxidants in fruits and vegetables, such as carotenoids, protect cells and tissues from damage caused by naturally occurring oxygen free radicals in the body. Such plant nutrients may help protect the skeleton by reducing oxidative stress and thereby inhibiting bone breakdown or resorption.
