In the 1960s, Ancer Keys, a US expert on nutrition, studied the health benefits of the Mediterranean diet for the first time. Since then many studies on the benefits of olive oil have been conducted. According to several studies performed in Italy, Spain and Greece (the main olive-oil-producing countries), the incidence of diseases is lower in these countries than in Northern Europe.

The Environmental, Biochemical and Nutritional Analytical Control research group, directed by Professors Alberto Fern?ndez Guti?rrez and Antonio Segura Carretero, used the most advanced analytical techniques for a precise study on the antioxidant properties of olive oil, characterized by its polyphenolic composition and its potential to combat degenerative diseases.

The study was completed with the collaboration of the Institut of Nutrition and Food Technology of the University of Granada [http://www.ugr.es] and the Nutrition Team of the Hospital Virgen de las Nieves (Granada). Together with the research group, they have determined that consumption of olive oil rich in polyphenols (natural antioxidants) improves the lives of people suffering from oxidative stress, and is also highly beneficial for the prevention of cell aging and osteoporosis.

This research has stirred the interest of the Control Board of the Designation of Origin Sierra Segura. After analysing samples from 15 olive oil mills, researchers have demonstrated that olive oil is very rich in polyphenols. According to Professors Alberto Fern?ndez and Antonio Segura, ?as preventive substances, polyphenols help to combat any oxidative disease associated with the degenerative process.?

The Environmental, Biochemical and Nutritional Analytical Control research group of the UGR [http://www.ugr.es] has carried out several related studies, such as the creation of a system aimed at guaranteeing the quality of bee honey and determining its geographical origin, or the polyphenolic characterization of food products such as honey, beer and propoils.

About the UNIVERSITY OF GRANADA

The University of Granada (UGR) was founded in 1531, under the initiative of Emperor Charles V. In this way, Granada asserted its vocation as a university city, open to different cultures, peoples and beliefs, continuing the tradition of the Arab University of Yusuf I (Madrassa, 14th century). With 475 years of tradition, the University of Granada has been an exceptional witness to history, as its influence in the city's social and cultural environment grew until it was to become, over a period of almost five centuries, an intellectual and cultural nucleus in Southern Spain in its own right. The University of Granada has also made a strong commitment to its future by fostering the development of quality research, whose guiding criteria are to stress traditional lines of research, to support investigation which - although less developed - may prove useful to a changing society and to forge bonds with firms and institutions. As a result of its growth in scientific production, the UGR is among the top Spanish universities. More than 400 research groups are working in all different areas of knowledge, in collaboration with both national and international research groups. The University of Granada offers to 81,600 students - 10 per cent of which are foreign students - 75 degree courses distributed in 28 centres. The UGR is the leading European destination for Erasmus/Socrates students, the most important Spanish university in graduation prizes, the third in the number of doctoral courses with the Distinction of Quality granted by the Ministry of Education and Science and the sixth in scientific production.
