There is a lot of information available (data, guidelines, resources) on what is healthy food. But they fail to provide an answer which can be used in real time by the consumer to get an answer if specific product is healthier or more risky. The data (e.g. https://health.gov/dietaryguidelines/2015/guidelines/ and http://openfood.schoolofdata.ch/food-allergens/) should be combined with personal physical condition and nutrient table recognition to provide a useful solution for people.
