A Mediterranean diet may lower the risk of hip fractures in postmenopausal women, says a new study.
The study was based on data from the Women's Health Initiative (WHI)- three clinical trials and an observational study initiated in 1991 by the National Institutes of Health which address the major health issues of postmenopausal women.
‘Postmenopausal women who had closely followed a Mediterranean diet were less likely to suffer a hip fracture compared to other women who followed other diets. ’
AdvertisementThe researchers examined whether diet affected bone health in postmenopausal women. They found that women who followed a Mediterranean diet were slightly less likely to suffer from hip fractures.
The Mediterranean diet has been linked to improving heart health and weight loss. The diet involves eating vegetables, fruits, nuts, beans and peas, unrefined grains, olive oil and fish. The amount of meat, dairy and saturated fat intake are limited. But the diet also allows a glass of red wine at dinner.
The study involved 90,014 women with an average age of 64. The participants described their diet in a WHI food frequency questionnaire at the beginning of the study. The dietary patterns were compared to four common healthy diets such as the Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH) and two others.
The researchers analyzed whether the women reported hip fracture during 16 years. At the end of the study period, there were 2,121 cases of hip fractures and 28,718 cases of total fractures. Women who followed a Mediterranean diet were 0.29% less likely to suffer from a hip fracture than women who did not follow the diet.
"Our results provide assurance that widely recommended eating patterns do not increase the risk of fractures," said lead study author Dr. Bernhard Haring of the University of Wurzburg in Germany.
"This being said, the average woman should follow a healthy lifestyle which includes adopting a healthy dietary pattern and being physically active."
Osteoporosis-related fractures are a major burden on health care systems in aging societies, with women particularly affected, said Dr. Haring.
The results of the study suggest that a healthy diet, specifically a Mediterranean diet, might play a small role in maintaining bone health in postmenopausal women. This study builds on previous evidence that health might benefit following a Mediterranean diet.
The Mediterranean diet has been linked to benefit brain health, increase life expectancy, aids in weight loss and lower the risk of cancer and cardiovascular diseases.
"At the present time, the U.S. health system almost entirely ignores nutrition in favor of pharmacology and is hugely expensive and ineffective compared to the systems in other countries," wrote Dr. Walter Willett of Harvard School of Public Health, in a related commentary. "Integration of the Mediterranean diet and related dietary patterns into medical practice, hospitals, schools and other institutions has the potential to improve well-being."
