Nice, just tried it out. I can think of a few changes that would certainly improve the user experience.
For one, it would be nice to build a list of "favorite foods" that you tend to eat frequently, secondly, the ability to enter and store recipes would be nice - it's rather tedious to enter all of the ingredients for some meals.
Maybe a longer term improvement would be a coaching function - after the analysis is complete, maybe suggest some changes to balance the diet, based on a user supplied goal.
Great work, thanks!
The question is, are you going to die sitting on the sofa - or doing something interesting?
