It's a very interesting ideas you introducing here. I can match music with mood, but I've never match food with mood. When i cook, i usually make whatever i find from my fridge. This is an new idea that can change people's behavior. Maybe instead of matching, you want to eat something to lighten your mood, for example, if you feeling anxious, eat a banana or some brown rice to alleviate their anxiety. You will have to research the different property of food though.
