Olive oil and bone health
The incidence of osteoporotic fractures is lower in Mediterranean countries. Virgin olive oil, a key component of the Mediterranean diet, with a recognized beneficial effect on metabolism and cardiovascular health, may reduce the risk of osteoporotic fractures, according to new clinical results.
Consumption of extra virgin olive oil, rich in polyphenols, is associated with a significant reduction in the risk of osteoporotic fractures, according to a study recently published in the Journal of Clinical Nutrition. The study investigated 870 middle-aged and elderly participants from the Mediterranean region and their effects on bone biochemical markers and osteoporotic fractures.
This research confirmed previous studies on olive polyphenols and provides further evidence for their potential for prevention and their beneficial effects on bone formation and metabolism. The study was conducted by researchers from the Prevención con Dieta Mediterranea (PREDIMED) in Madrid who assessed the effect of the Mediterranean diet in Spain through a data questionnaire on the dietary intake of men aged 55-80 years and women aged 60-80 years who showed an increase cardiovascular risk. The questionnaire concerned the consumption of different types of olive oil: extra virgin olive oil (EVOO), refined and kernel oil.
People with the highest intake of extra virgin olive oil (average intake 55.35. 4.62 g / day) had a 51% lower risk of osteoporotic fractures. No relationship was found between the ratio of monounsaturated / polyunsaturated fatty acids and the risk of fractures. This suggests that the polyunsaturated fatty acids present in extra virgin olive oil are not responsible for the positive effect on bone health but phenols. This finding enhances the beneficial role of phenolic compounds present in extra virgin olive oil compared to others which contain a small amount of these bioactive compounds.
Previous studies have also shown that olives, olive oil and their polyphenols can be considered bone protectors. In particular, women who ate olive oil and followed a Mediterranean diet were less likely to suffer from hip fractures.

The unlimited beneficial properties of extra virgin olive oil help our good health in many ways.
Olive oil is the protagonist of the Mediterranean diet and since ancient times our ancestors had realized its value.
Olive oil is associated with a reduced risk of developing cancer since its components (the phenolic compound also known as oleocanthal) can be selected to kill cancer cells while leaving healthy cells intact, the researchers say.
Regular use of olive oil has been found to reduce cardiovascular risk factors for women suffering from fibromyalgia, according to a new study.
Which oil is right for you? This largely depends on the type of cooking you do. The oil smoke point, which is where the oil begins to burn and smoke, is one of the most important things to consider.
