From an epidemiological point of view, nutrition plays a role in the pathogenesis of the most common diseases, but edible plants can concretely contribute to improve human health. Natural products in various forms have been used since the most ancient times for the treatment of pathological conditions and for health benefits all over the world. A standardized approach to dietary antioxidant treatment is an open field where edible plants can contribute to optimise nutrition. Products obtained from tea, grape, bilberry and olive, as well as additional plants belonging to the rich portfolio of Western and Eastern countries, once properly investigated, could also contribute to maintain healthy physiological functions and reduce the risk of some major pathologies. Indena has been working for over 80 years in the research of medicinal and edible plants, developing and assessing the use of functional botanical extracts in various ''delivering formats'', including some food matrix. Clinical trials support the efficacy of these extracts. To know more, check www.indena.com or contact us.
