Mediterranean Diet Protects Bones

Thursday, 16 Aug 2012 12:07 PM


Eating a Mediterranean diet enriched with olive oil for two years may protect aging bones, according to a study to be published in the Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM).
Age-related bone mass loss and decreased bone strength affect women and men alike and are important determinants of osteoporosis and fracture risk. Studies have shown that the incidence of osteoporosis in Europe is lower in the Mediterranean basin. The traditional Mediterranean diet, rich in fruits and vegetables, with a high intake of olives and olive oil could be one of the environmental factors underlying this difference.
"The intake of olive oil has been related to the prevention of osteoporosis in experimental and in vitro models," said José Dr. Manuel Fernández-Real of Hospital Dr. Josep Trueta in Girona, Spain and lead author of the study. "This is the first randomized study which demonstrates that olive oil preserves bone, at least as inferred by circulating bone markers, in humans."
The participants in this study were 127 men aged 55 to 80 years old. All were without prior cardiovascular disease but had a diagnosis of Type 2 diabetes had at least three cardiovascular risk factors, namely hypertension, high cholesterol, or a family history of premature cardiovascular disease. Participants were randomly assigned to three intervention groups: Mediterranean diet with mixed nuts, Mediterranean diet with virgin olive oil, and a low-fat diet.
Biochemical measurements of osteocalcin (a protein found in bone), glucose, total cholesterol, HDL-cholesterol, and triglycerides were performed at baseline and after two year follow-up on fasting blood samples. Researchers found that only consumption of the Mediterranean diet with olive oil was associated with a significant increase in the concentrations of total osteocalcin and other bone formation markers. There were also no significant changes in serum calcium in subjects taking olive oil whereas serum calcium decreased significantly in the other two groups.
