Washington, Nov 10 (ANI): Consumption of dairy foods and higher protein may improve bone health during diet and exercise in overweight premenopausal women, a new study has suggested.
Stuart Phillips and his team from the McMaster University in Hamilton, Ontario conducted a controlled randomised weight loss intervention trial involving 90 premenopausal overweight or obese women which was designed to achieve weight loss and be supportive of bone health.
They employed modest dietary calorie restriction and daily exercise including aerobic and resistance training with varied intakes of protein and dairy foods.
The researchers used dual-energy X-ray absorptiometry (DXA) scans to assess bone mineral density and content, and analyzed participants' urine and blood samples to evaluate serum levels of several bone health biomarkers.
They found that consumption of diets higher in protein with an emphasis on dairy foods during a diet and exercise period, positively affected markersof bone turnover, calcium, vitamin D status and bone metabolism in overweight and obese premenopausal women.
"Our findings show that a diet with a high proportion of dairy foods and higher than recommended protein intake was associated with improved markers for bone health," Phillips, senior author of the study, said.
"Thus, to avoid deleterious consequences to their bone health, women who are attempting weight loss through dieting should practice consumption of more protein from dairy sources," he added.
The study has been accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM). (ANI)
