NeuroDiet

From Neural Planner Software:

NeuroDiet is a neural network application that learns how the foods you eat are related to your health and fitness. All the neural network functions are managed automatically. You don't need to know anything about neural networks. All you need to do is tell NeuroDiet how your symptoms are changing and which foods you are eating. Every day NeuroDiet will produce a list of foods that may be causing problems with your health and fitness.
