Several recent studies have confirmed what traditional oriental medicine has known for centuries—that dried plums have the capacity to prevent and even reverse bone loss that can occur in our later years.
More recently Florida State University researchers tested 236 women who were between one and ten years into menopause. The women were randomly divided into two groups. One group was given 100 grams of dried plums per day while the other group was given 100 grams of dried apples per day for a year. After doing bone scans at three months, six months and twelve months, the researchers found that the dried plum group showed significantly greater bone mineral density than those women consuming the dried apples over that same period.
In the recent study, biomarkers such as alkaline phosphatase and tartrate-resistant acid phosphatase-5b levels were significantly lower in the dried plum group, for example. These indicate a slower turnover of bone minerals and reduced bone loss.
The research was led by Dr. Bahram Arjmandi, Professor and Chair of Florida State’s Nutrition, Food, and Exercise Sciences Department. Dr. Arjmandi commented on the research.
“Dried plums are the most bone-friendly fruit that I have seen in decades. They are nature’s solution to maintaining good bone health. Over my career, I have tested numerous fruits, including figs, dates, strawberries and raisins, and none of them come anywhere close to having the effect on bone density that dried plums have,” wrote Dr. Arjmandi.
Dr. Arjmandi has also found that California plums seem to provide some of the best nutrient levels.
“Incorporating California dried plums (prunes) into holiday recipes is a step in the right direction. After people start cooking with and snacking on them they love the taste. The good news is they are good for you.”
California produces 99 percent of the dried plums consumed in the United States and 48 percent of the world’s supply of dried plums.
What is the difference between dried plums and prunes? Only the name. In 2000, the U.S. Food and Drug Administration accepted a new identity standard—changing prunes to dried plums—a more accurate description.
These plum findings are confirmed by a study conducted by researchers at Oklahoma State University who looked at post-menopausal mice. For eight weeks, the mice were given either a control diet or a diet that was supplemented with dried plum or other fruits.
Those mice given dried fruit were given dried plum, dried mango, dried apple or dried grape for the eight-week period to determine whether dried fruit, in general, produced the effect or specifically the dried plums. Only the dried plum diet prevented bone loss among the mice.
The researchers also found that the dried plum diet also reversed bone loss among the aging female mice.
