Many elderly suffer from nutritional problems that can cause (or can be caused by) a number of complications such as weakened immune systems and chronic health conditions, such as diabetes type 2, high blood pressure, cardiovascular diseases, stroke or even osteoporosis. Through appropriate adjustments in their diets, on the basis of nutritional advice, the burden of established diseases as well as the risks of developing further conditions can be diminished.
The goal of our proposed project LIFANA is to develop and evaluate the LIFANA Nutrition Solution (Figure) to support healthy nutrition through all phases of ageing – from active seniors to elderly users and patients in need of daily care. Individual meal recommendations and decision support in the supermarket will assist the users to change their eating habits in order to maintain a healthier lifestyle and increase their quality of life. Our objective is to integrate, adapt and extend existing components for meal-planning (Fraunhofer Nutrition application, FhP) and shopping assistance (WikiFoodR, LIST) from the research partners into our business partner GOC’s existing smartphone software, which targets the special needs of elderly users (GoLivePhoneR) and caregivers (GoLiveAssistR).
The LIFANA Nutrition Solution will be cocreated with primary end-users through the help of end-user organisations in the Netherlands (KBO) and Portugal (SCML), but also tailored towards the needs of secondary end-users, such as professionals from healthcare care organisations, represented in LIFANA by our Swiss clinical partner CER.
In the end, the LIFANA solution will be marketed by GOC as part of their GoLive product family. Central to our integrated solution is a meal planning recommender system, having its roots in the AAL project CordonGris, which suggests meals for a whole week based on the user's personal profile. This may include general preferences, such as culture, taste, and budget, but more importantly automated and personalised nutritional recommendations based on advice provided by professional nutritionists and allergists.
The goal will be to include dishes that are nutritionally appropriate on their own and that the user likes (or are similar to the dishes the user is known to like). In addition, we will strive for the appropriateness of the whole menu (nutrient balance, calorie content, diversity, allergies). The meals will be adapted to the different regional cultures within the EU. Depending on the individual abilities and situation of the user, the package will further support (i) shopping tasks for self-cooking, (ii) coordination of shopping tasks with informal carers, and (iii) grocery delivery services.
