Monocultivar Coratina Extra Virgin Olive Oil in UC Patients

Summary

Epidemiological studies suggest that daily intake of fruits and vegetables high in polyphenols or the addition of olive oil containing many polyphenols is associated with a reduced risk of chronic diseases including cardiovascular, metabolic, neurodegenerative, and inflammatory bowel conditions. In vivo experiments demonstrated that the administration of a diet associated with daily intake of extra virgin olive oil (EVOO) reduces histological lesions and symptomatology in rats with a dextran sulfate sodium (DDS) induced colitis. A diet supplemented with hydroxytyrosol (a component of olive oil) showed a reduction of the inflammatory process at the inflamed colon of the rats.
