Ageing of the population is a major event in the world. Gerontological/geriatric literature unanimously indicate that physical exercise and diet are at present the two available fundamental approaches to contrast/prevent most of the age associated alterations. In the elderly the inflammageing, the oxidative stress and the alteration of the intestinal microbiota can be influenced by nutritional status and possibly corrected by an appropriate dietetic intervention:

Nowadays the nutraceutical food supplements become an opportunity for the consumer to improve the quality of individual diet for specific needs This study will focus on the development of a specific dietary approach through an E-Health dietary service, associated or not to nutraceutical food supplements intake, to modulate the oxidative stress, inflammageing and gut microflora in the elderly people.
