Dean Pomerleau Posted November 6, 2015 Report Share Posted November 6, 2015 Tea Reduces Fracture Risk All, A new prospective study  reported on here found that elderly women who drank the most tea had a 30% reduced risk of osteoporotic fractures compared with women who abstained from drinking tea. In the study, researchers followed ~1200 women age 75+ for 10 years and associated their tea drinking habits with subsequence risk of fracture. Here is the highlight from the abstract: In comparison with the lowest teaintake category (≤1 cup/wk), consumption of ≥3 cups/d was associated with a 30%decrease in the risk of any osteoporotic fracture (HR: 0.70; 95% CI: 0.50, 0.96).Compared with women in the lowest tertile of total flavonoid intake (from tea anddiet), women in the highest tertile had a lower risk of any osteoporotic fracture(HR: 0.65; 95% CI: 0.47, 0.88), major osteoporotic fracture (HR: 0.66; 95% CI:0.45, 0.95), and hip fracture (HR: 0.58; 95% CI: 0.36, 0.95). No mention is made of a comparison between the relative effects of black vs. green tea on fracture risk in this cohort. Given the subjects were Australian women, it is likely they were drinking mostly black tea so no meaningful comparison could be made. I recently started drinking a combination of black and green tea based on suggestive evidence that black tea may have some health benefits that green tea does not, and visa versa. This study could be interested as further (albeit weak) support such a strategy. --Dean P.S. Here is a nice infographic on the health benefits of Coffee vs. Tea, although bone health isn't mentioned as a benefit for either one. ---------------  Am J Clin Nutr. 2015 Oct;102(4):958-65. doi: 10.3945/ajcn.115.109892. Epub 2015Aug 12.Tea and flavonoid intake predict osteoporotic fracture risk in elderly Australianwomen: a prospective study.Myers G(1), Prince RL(2), Kerr DA(3), Devine A(4), Woodman RJ(5), Lewis JR(2),Hodgson JM(6).BACKGROUND: Observational studies have linked tea drinking, a major source ofdietary flavonoids, with higher bone density. However, there is a paucity ofprospective studies examining the association of tea drinking and flavonoidintake with fracture risk.OBJECTIVE: The objective of this study was to examine the associations of blacktea drinking and flavonoid intake with fracture risk in a prospective cohort ofwomen aged >75 y.DESIGN: A total of 1188 women were assessed for habitual dietary intake with afood-frequency and beverage questionnaire. Incidence of osteoporotic fracturerequiring hospitalization was determined through the Western Australian HospitalMorbidity Data system. Multivariable adjusted Cox regression was used to examinethe HRs for incident fracture.RESULTS: Over 10 y of follow-up, osteoporotic fractures were identified in 288(24.2%) women; 212 (17.8%) were identified as a major osteoporotic fracture, andof these, 129 (10.9%) were a hip fracture. In comparison with the lowest teaintake category (≤1 cup/wk), consumption of ≥3 cups/d was associated with a 30%decrease in the risk of any osteoporotic fracture (HR: 0.70; 95% CI: 0.50, 0.96).Compared with women in the lowest tertile of total flavonoid intake (from tea anddiet), women in the highest tertile had a lower risk of any osteoporotic fracture(HR: 0.65; 95% CI: 0.47, 0.88), major osteoporotic fracture (HR: 0.66; 95% CI:0.45, 0.95), and hip fracture (HR: 0.58; 95% CI: 0.36, 0.95). For specificclasses of flavonoids, statistically significant reductions in fracture risk wereobserved for higher intake of flavonols for any osteoporotic fracture and majorosteoporotic fracture, as well as flavones for hip fracture (P < 0.05).CONCLUSION: Higher intake of black tea and particular classes of flavonoids wereassociated with lower risk of fracture-related hospitalizations in elderly womenat high risk of fracture.PMID: 26269364 Link to comment Share on other sites More sharing options...
