Nutraceuticals and foods of interestResearch is focused on studying the beneficial effects of polyphenols present in olive oil. We demonstrated that hydroxytyrosol promotes the production of new neurons from neural stem cells in the aged hippocampus. With F.Tirone and M. Caruso,we are now evaluating the effects of oral administration of hydroxytyrosol and polyphenolic extracts from oil production waste products on 1) cognitive abilities and stress, 2) muscle regeneration and metabolism, 3) composition of the microbiota, in aged mice. Olive oil, hydroxytyrosol, polyphenolic extracts from oil production waste products obtained in collaboration with laboratories of Prof. C. Caruso and Prof. R. Bernini (DEB and DAFNE, Università della Tuscia, Viterbo). Fields of application Biological validation of natural compounds from olive oil for the production of dietary supplements. Aging is a complex process that involves the progressive decline of various physiological systems and that represents a challenge for the health and socio-economic system. Cognitive impairment, progressive loss of muscle mass and strength and alterations in the composition of the intestinal microbiota are highly significant pathological traits associated with aging that can be prevented or delayed by adhering to the Mediterranean diet (MD). Olive oil is an essential MD component. Its production is associated with a large amount of waste and by-products, which have negative impacts on the environment, but which represent an important possible source of bioactive phenolic compounds. Facilities and equipments The laboratories are well equipped with all the basic instruments.
