A study in postmenopausal people suggests eating nutrient-rich prunes every day may be beneficial to bone health, reducing inflammatory factors that contribute to osteoporosis. The research will be presented this week in Philadelphia at the American Physiological Society’s (APS) annual meeting at Experimental Biology 2022.

An estimated 13.6 million people in the U.S. over the age of 50 will develop osteoporosis—a loss of bone strength caused by reduced mineral density of the bones—by the year 2030. Osteoporosis increases the risk of fracture, especially in older adults. People who experience menopause have lower levels of estrogen, which trigger an increase in inflammation in the body, which can also contribute to bone loss.

Previous research has shown that polyphenol extracts—plant compounds that act as antioxidants and reduce inflammation—in prunes promote lower levels of oxidative stress and inflammation in a type of bone cell called osteoclasts. In a new study, researchers from the Integrative and Biomedical Physiology Program and the Departments of Nutritional Sciences and Kinesiology at The Pennsylvania State University explored the effects of prunes on bone health after menopause.
