Every day prunes shifted some bone biomarkers in older males, however after 12 months, they didn’t ship measurable positive aspects in bone mineral density past commonplace calcium and vitamin D3 assist.

In a latest research printed within the journal Vitamins, researchers assessed the results of 12 months of prune supplementation on bone well being in older males with osteopenia.
Osteoporosis is characterised by reductions in bone high quality and bone mineral density (BMD), elevating the danger of fractures, morbidity, and mortality. Over 53 million folks aged ≥50 years or older have low bone mass in the US (US). Of those, 10 million have osteoporosis, together with two million males. Males lose about 0.5% to 1% of their bone mass annually after age 60.
Though pharmacological therapies can be found for osteoporosis, they’ve poor adherence and adversarial results, together with musculoskeletal ache, urinary and pores and skin infections, and gastrointestinal misery. As such, different or complementary therapeutic approaches could also be wanted. Research counsel that some greens and fruits comprise polyphenols which might be bone- and cardiovascular-protective.
Particularly, prunes exhibit a excessive antioxidant capability, with research reporting constructive physiological results, together with on bone metabolism. The bone-protective results of prunes have been demonstrated in animal fashions, with constructive findings reported in people. Nevertheless, research on bone well being and prune supplementation particularly in male populations are scarce.
Concerning the Examine
Within the current research, researchers investigated the results of prune consumption on bone well being in older males with osteopenia. Eligible members have been males aged 55–80 years with a lumbar backbone BMD T-score of −0.1 to −2.5 commonplace deviations beneath the imply, a spread that included males with osteopenia and males with detrimental T-scores that didn’t meet osteopenia standards. Males taking endocrine/neuroactive medicine or different brokers that affect bone metabolism, and people who had not too long ago initiated train applications that have an effect on bone, have been excluded.
People with renal illness, diabetes, heart problems, most cancers, metabolic bone illness, liver illness, gastrointestinal illness, respiratory illness, or every other persistent illness have been additionally excluded. Contributors have been randomized to devour 50 g of prunes, 100 g of prunes, or a multivitamin (management; no prunes) day by day for one yr. All teams have been supplemented with 800 IU vitamin D3 and 450 mg elemental calcium all through the research interval.
Compliance was self-reported utilizing a day by day dosing calendar. Contributors visited the research laboratory at baseline and at three, six, and 12 months, when fasting blood samples have been collected, anthropometrics have been measured, and whole-body and lumbar backbone dual-energy X-ray absorptiometry (DXA) scans have been carried out. A 3-day meals file was used to judge dietary consumption at these time factors.
Bodily exercise and sleep have been decided utilizing the 5-Metropolis Challenge Bodily Exercise Questionnaire at research visits. Blood strain (BP) and resting coronary heart fee (RHR) have been recorded. C-reactive protein (CRP) and bone biomarkers, equivalent to osteocalcin, osteoprotegerin (OPG), tartrate-resistant acid phosphatase 5b (TRAP5b), and sclerostin (SOST), have been measured utilizing enzyme-linked immunosorbent assays (ELISA).
Findings
Sixty-two males have been enrolled, and 59 accomplished the 12-month research protocol. The imply age of members was 67 years. At baseline, controls had considerably greater weight and waist circumference than the 100 g prune group and considerably greater physique mass index (BMI) than each prune teams. There was a major lower in RHR within the 50 g prune group.
Systolic BP confirmed an total lower over time in all teams, however this was not reported as a prune-specific cardiovascular impact. Bodily exercise and sleep didn’t differ between teams and didn’t considerably change over time. Likewise, complete BMD and lumbar BMD didn’t differ between teams, and there have been no important modifications over time. Controls had considerably greater CRP than the 50 g prune group all through the research, however CRP didn’t change considerably over time.
OPG decreased considerably over time in all teams, with the discount larger in controls than within the prune teams. Osteocalcin didn’t differ between teams, and there have been no important temporal modifications. SOST and TRAP5b confirmed important will increase over time throughout all teams. Notably, controls had a considerably larger enhance over time in TRAP5b than the 100 g prune group, though these secondary biomarker variations didn’t correspond to detectable BMD modifications and must be thought-about exploratory.
Conclusions
In sum, one-year prune supplementation didn’t enhance lumbar backbone or complete BMD in older males. Furthermore, supplementation didn’t assist keep bone density past ranges attainable with vitamin D3 and elemental calcium. Though BMD didn’t decline considerably over the research interval, this sample was noticed throughout all teams, together with controls, so it can’t be attributed particularly to prune consumption.
The research’s limitations embrace a small pattern measurement, group imbalance, COVID-19-related disruptions, a broad T-score eligibility vary, comparatively wholesome members, exclusion of males with main persistent ailments, restricted geographic and demographic range, potential unmeasured confounding, and the dearth of a real placebo arm that didn’t obtain any supplementation, amongst others. Furthermore, as a result of compliance was self-reported, discrepancies might exist between logging types and precise consumption.
Additional, larger-scale, longer-duration analysis is required to deepen understanding of the impression of prunes on bone well being in males.
