The Mediterranean diet helps to maintain the health of the skeletal system for longer. 

Adherence to this style of eating for two years shows benefits for maintaining bone strength at a later age, according to a study. 
It has already been proven that the Mediterranean style of eating improves brain activity, fertility, heart health, reduces the risk of heart attack and the development of malignant diseases.
Previous studies have shown that people living in the Mediterranean region have a lower risk of osteoporosis than in Northern Europe, which may be due to various dietary factors, experts say.
The Mediterranean diet includes high consumption of fruits, vegetables, fish, nuts, whole grains and healthy fats, such as those in olive oil, and avoid consumption of red meat and dairy products.
According to a new study, this eating style provides additional benefits to the skeletal system. The research team found that those who consumed more olive oil had high levels of the hormone osteocalcin in the blood, which is linked to bone strength.
The experiment involved 127 people who followed a Mediterranean diet with three main differences - an emphasis on mixed nuts, consumption of at least 50 ml of raw olive oil a day, and a low-fat diet.
Participants regularly use olive oil for cooking and dressing for salads, eat more fruits and vegetables, drink moderate amounts of red wine and avoid consuming red meat, butter, cream, cakes, hard alcohol and visiting fast food restaurants.

Olive oil is rich in healthy omega-6 fats. 
Two years later, olive oil consumers were found to have significant increases in concentrations of osteocalcin and other markers associated with bone formation. 
The other two diets do not show the same effect, said Dr. Jose Manuel Fernandez-Real of the Josep Trueta Hospital in Girona, Spain. 
The results are published in the Journal of Clinical Endocrinology and Metabolism .
