Yogurt consumption in older adults linked with better bone health.
The largest observational study to date of dairy intakes and bone and frailty measurements in older adults has found that increased yogurt consumption was associated with a higher hip bone density and a significantly reduced risk of osteoporosis in older women and men on the island of Ireland, after taking into account traditional risk factors.
The study led by Trinity College Dublin in collaboration with St James's Hospital Dublin and co-investigators from Nutrition at Ulster University, Coleraine investigated participants from the Trinity Ulster Department of Agriculture (TUDA) ageing cohort study.
Total hip and femoral neck bone mineral density measures in females were 3.1-3.9% higher among those with the highest yogurt intakes compared to the lowest and improvements were observed in some of the physical function measures (6.7% better).
After adjusting for all these factors, each unit increase in yogurt intake in women was associated with a 31% lower risk of osteopenia and a 39% lower risk of osteoporosis.
In men, a 52% lower risk of osteoporosis was found.
Vitamin D supplements were also associated with significantly reduced risks both in men and women.
Osteoporosis is a chronic condition associated with a reduction in bone strength and an increased risk of bone fracture.
The data suggest that improving yogurt intakes could be a strategy for maintaining bone health but it needs verification through future research as it is observational."
The TUDA study was funded by the Irish Department of Agriculture, Food and the Marine Food Institutional Research Measure initiative and the Northern Ireland Department for Employment and Learning (DEL), Cross-Border Research and Development Programme: "Strengthening the all Island Research Base".
