prunesevery day can be beneficial for bone health by reducing inflammatory factors that contribute to osteoporosissuggests a study in postmenopausal women to be presented this week in Philadelphia at the American Physiological Society (APS) annual meeting in Experimental Biology 2022.
In Spain, nearly 3 million people, most of them women, suffer from osteoporosis, a pathology that thins and weakens the bones so that they become brittle and break easily.
It is estimated that in 2030, 13.6 million people over the age of 50 in the US will develop this disease. Women, after menopause, see reduced your estrogen levelswhich triggers increased inflammation in the body, which can also contribute to bone loss.
Previous research has shown that extracts of polyphenols (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.
A new study, conducted by researchers from the Program for Integrative and Biomedical Physiology and the Departments of Nutritional Sciences and Kinesiology at Pennsylvania State University, has explored the effects of prunes on bone health after menopause.
The participating women, who had a low bone mineral density score (a marker of osteoporosis), were divided into three groups: one group ate 50 grams of prunes (about six pieces) daily for 12 months; a second group ate 100 grams of prunes (about 12 pieces) daily for 12 months; and a control group ate no prunes.
The research team analyzed blood samples taken from all the volunteers before and after the trial and found significant reductions in inflammatory markers in the two groups that took the prunes compared to the control group.
“Our findings suggest that consuming six to 12 prunes per day may reduce pro-inflammatory mediators that may contribute to bone loss in postmenopausal women. Therefore, prunes could be a promising nutritional intervention to prevent the increase in inflammatory mediators that are often seen as part of the aging process,” concludes Janhavi Damani, first author of the study.
