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, Ireland, 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) aging cohort study (>5000 people).
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). In men, the biomarker of bone breakdown was 9.5% lower in those with the highest yogurt intakes compared to the lowest. This is an indication of reduced bone turnover.
A new study out of Trinity College in Dublin, Ireland has found positive correlation between yogurt consumption and bone health.
Considered the largest observational study of dairy intake and bone and health to date. The study focused on older adults in Ireland. The researchers found that higher hip bone density and a significantly reduced risk of osteoporosis in older populations was associated with an increased yogurt consumption after taking into account traditional risk factors.
The Brittish National Osteoporosis Society (NOS) is warning that the current eating habits of teenagers and young adults is a ticking time bomb for their bones and time is running out for them to prevent permanent damage.
A survey carried out on behalf of the NOS has found that 70% of 18 – 35 year olds are currently, or have previously been, dieting. In addition, 20% had cut or significantly reduced dairy in their diet. Dairy is an important source of calcium, vital in building bone strength when you are young.
Maintaining a calcium intake of at least 1000-1200 mg/day has long been recommended for older individuals to treat and prevent osteoporosis. Calcium supplements are commonly taken to achieve such intakes, which are considerably higher than the average intake of calcium in the diet in older people in Western countries, around 700-900 mg/day. Recently, concerns have emerged about the risk-benefit profile of calcium supplements. The small reductions in total fractures seem outweighed by the moderate risk of minor side effects such as constipation, coupled with the small risk of severe side effects such as cardiovascular events, kidney stones, and admission to hospital with acute gastrointestinal symptoms.
The study concludes: Increasing calcium intake from dietary sources or by taking calcium supplements produces small non-progressive increases in BMD, which are unlikely to lead to a clinically significant reduction in risk of fracture.
