Daily Yogurt Consumption Leads to Better Bone Health

Healthy postmenopausal women who eat at least one serving of yogurt a day have a lower body mass index (BMI), less fat, and better bone density — at least at some skeletal sites — than women who never consume yogurt, new research shows.  Over time, women who ate yogurt also had less cortical bone loss than women who never ate it, and this was independent of any other factor that could account for differences in bone density, such as physical activity and total calcium intake.  The data suggest that there is a possible protective effect of fermented dairy products on postmenopausal cortical bone loss.

At baseline, women who consumed yogurt (over 91% of the cohort) had a 4.4% higher bone-mineral-density (BMD) value at the lumbar spine than women who never consumed yogurt.  Women who consumed yogurt were also 6.4% leaner than those who never ate it, again independent of total energy intake and physical activity.

At the follow-up assessment 3 years later loss of BMD at the total hip and at the distal radius was attenuated among yogurt consumers, and this effect was again independent of BMI, physical activity, and total calcium and protein intake.  In contrast, no significant difference was seen in BMD at the lumbar spine between yogurt consumers and nonconsumers.

Bacteria contained in high-quality yogurt are also present to ferment the milk, and these bacteria populate the large intestine, where they improve calcium absorption and decrease inflammation.  Fermented dairy products may have a favorable influence on the gut microbiota, which is now implemented in a wide range of disorders, including skeletal health.
