It is already well-known that prunes are good to your intestine, however new Penn State analysis suggests they might be good for bone well being, too.
In a analysis overview, the researchers discovered that prunes may help stop or delay bone loss in postmenopausal ladies, presumably attributable to their capacity to cut back irritation and oxidative stress, each of which contribute to bone loss.
“In postmenopausal women, decrease ranges of estrogen can set off an increase of oxidative stress and irritation, rising the danger of weakening bones that will result in fractures,” stated Connie Rogers, affiliate professor of dietary sciences and physiology. “Incorporating prunes into the eating regimen might assist defend bones by slowing or reversing this course of.”
The overview was just lately revealed within the journal Advances in Vitamin.
Osteoporosis is a situation by which bones develop into weak or brittle that may occur to anybody at any age, however in line with the researchers is most typical amongst ladies over the age of fifty. The situation impacts greater than 200 million ladies worldwide, inflicting virtually 9 million fractures annually.
Whereas medicines exist to deal with osteoporosis, the researchers stated there’s a rising curiosity for tactics to deal with the situation with diet.
“Fruit and veggies which might be wealthy in bioactive compounds reminiscent of phenolic acid, flavonoids and carotenoids can probably assist defend in opposition to osteoporosis,” stated Mary Jane De Souza, professor of kinesiology and physiology, “with prunes particularly gaining consideration in earlier analysis.”
In keeping with the researchers, bones are maintained all through grownup life by processes that frequently construct new bone cells whereas eradicating outdated ones. However after the age of 40, this breaking down of outdated cells begins to outpace the formation of latest ones. This may be brought on by a number of components together with irritation and oxidative stress, which is when free radicals and antioxidants are unbalanced within the physique.
Prunes, nonetheless, have many dietary advantages reminiscent of minerals, vitamin Ok, phenolic compounds and dietary fiber—all which could possibly assist counter a few of these results.
For his or her overview, the researchers analyzed knowledge from 16 preclinical research in rodent fashions, ten preclinical research and two medical trials. Throughout the research, the researchers discovered proof that consuming prunes helped cut back irritation and oxidative stress and promoted bone health.
For instance, the clinical trials discovered that consuming 100 grams of prunes—about 10 prunes—every day for one 12 months improved bone mineral density of bones within the forearm and decrease backbone and decreased indicators of bone turnover.
Moreover, consuming 50 or 100 grams of prunes a day for six months prevented lack of complete bone mineral density and decreased TRAP-5b—a marker of bone resorption—in comparison with ladies who did not eat prunes.
“Taken collectively, proof from in vitro, preclinical studies, and restricted medical research recommend prunes might assist to cut back bone loss,” Rogers stated. “This can be attributable to altered bone turnover and by inhibiting irritation and suppressing markers of oxidative stress.”
The researchers stated one potential mechanism for the results is prunes triggering a change within the gut microbiome that then lowers irritation within the colon. This may increasingly then decrease ranges of pro-inflammatory cytokines and markers of oxidative harm.
Sooner or later, the researchers plan to additional report on the results of prune consumption for 12 months on bone outcomes, inflammatory pathways and the intestine microbiota in a randomized managed trial that was led by De Souza.
