Gratitude to my wife (and office manager) for sharing this interesting study, published in 2022, with me.
Researchers at Penn State University randomly assigned 235 post-menopausal women to either eat 50 grams of prunes (aka dried plums) or not every day for a year. For context, 50 grams of prunes is about six prunes per day. After a year, they found that the women eating the prunes had better bone mineral density, and an accordingly lower estimated risk for bone fractures, than the women who weren’t.
In other words, doing absolutely nothing other than adding six prunes per day to your diet might be a tool to keep your bones healthy, at least in post-menopausal women.
