it would be interesting to try to constrain / regularize this problem such that the solution is palatable. User could answer some questions about ingredient preferences to build approximate set of weights for the LP objective. Also easy to add some constraints that prevent huge amounts of one food. Tools to allow the user to "critique" the solution which generate new constraints or modify the objective. Also would be interesting to run the same LP over historical ingredient price datasets and see how the optimal diet changes as ingredient prices fluctuate.
