The disclosed system calculates a single score for a consumable that indicates the nutritional health of that consumable. Nutritional health in one embodiment is an indication of whether nutrients within a consumable are within a healthy range that is specific to a user based on a recommended caloric intake. The system determines the impact on the individual's nutritional health by determining whether the nutritional content of a consumable falls within a range customized to the individual. This range may be calculated by, for example, using a plurality of possible minimum intake values and an upper limit (if one exists) for each nutrient. In an embodiment, the system particularly emphasizes the impact, when negative, of consuming amounts of nutrients that are outside of a pair of endpoints that define a healthy amount of the nutrient for consumption.
