This paper gives an overview of the MenuGene nutrition counseling expert system and
its main components, focusing on home health monitoring / dietary logging. Published
solutions so far can satisfy nutrient constraints, but does not take harmony rules
into account. The novelty of the algorithm used by MenuGene is that dietetic knowledge
including harmony rules can take part of the menu synthesis process. Our results show
that a considerable part of dietary counseling can be extended by computer aided approach,
if we provide easy to use interfaces for patients and dietetic experts. According
to our tests with volunteers an average logging accuracy of ca. 15% can be achieved
with our Dietlog web interface.
