Personalized Nutrition Advice for Optimizing Dietary Habits and Metabolic Status

"A digital environment which combines biological information, personal habits and preference to provide nutritional recommendations. This digital environment is composed by the follow softwares:1. The recommender system: software that combine the behavioral and biological information about the volunteer and generates personalized nutritional recommendations; 2. The ALDI microsite: A microsite that retrieves the personalized recommendations for the volunteer from the recommender system. The ALDI microsite matches food categories with products of the ALDI catalogue. As a result, the volunteer receives a list of products classified under different food categories that are recommended for him/her. Next to each food category, the number of servings recommended (weekly or daily) is also shown.~The ALDI microsite is a tool only to elaborate a shopping list through personalized recommendations. Therefore, volunteers can choose to buy their food shopping list at wherever store other from ALDI."

Participants will use the same software described in for the Personalized nutrition group together with a behavioral change program designed to increase the adherence to the recommendations provided by the ALDI microsite by promoting a proper attitude by means of a series of personalized, goal-orientated, friendly, achievable actions delivered periodically to the volunteer. The behavioral change program will be fed with the results of behavior questionnaires. The personalized messages will be delivered through the ALDI microsite. These personalized messages will be available only for those subjects engaged in the Personalized Plan group.

The participants in the control group will not have personalized recommendations. These participants will have access to a restricted version of the ALDI microsite where the list of recommended products correspond to categories that are general recommendations according to Mediterranean diet.
