Love this for prepared meals and home cooked meals, where you need to analyze the ingredients of a dish. Have you considered adding the ability to recognize a standard FDA Nutrition facts label as well? For example if I have a protein bar, it would be great to snap a picture of the label and OCR the macros. I know that differs though from your current tech of a CNN for image analysis, but it would round out the product to cover a greater percent of foods eaten.
