A poor nutritional state, as is the case for many people
today, can increase risks for cancer, cardiovascular disease
and obesity. Technology supported approaches could
potentially be used to positively influence food
consumption. We present the Nutriflect system, which
utilizes users´ shopping data to inform them about their
long term shopping behavior. In an initial study we
conducted structured interviews in grocery stores. Based on
the results we implemented a system that visualized a
household´s collective shopping information via situated
displays. The aim was to raise awareness about shopping
habits and to enable reflection about nutrition without
burdening the users with the manual entry of their eating
habits. We evaluated the system in a 4 week field study in 8
households with 21 users. The results indicate that
contextually situated displays, showing shopping patterns
against personal nutrition goals, can foster a reflective and
respectful approach towards better shopping and nutrition.
