1. A system for aligning a person'"'"'s diet with specific dietary goals, the system comprising:

  • an input port configured to receive (1) data representative of a dietary program comprising a user-designed or a user-selected dietary program for the person and (2) data representative of one or more foods consumed by the person, wherein the dietary program includes a nutrition-related goal for the person;

    at least one computer processor, in communication with the input port and an electronic database configured to store nutritional information related to a plurality of foods, the at least one computer processor configured to;

    generate, based on the dietary program, a target nutritional profile including a target level for each of a plurality of target nutrients associated with the dietary program, wherein the target nutrients include a plurality of micronutrients and a plurality of macronutrients;

    generate, based on the nutritional information in the electronic database, a consumed amount for each of a plurality of consumed nutrients associated with the one or more foods previously consumed by the person;

    compute a deviation for each of the target nutrients by comparing the target level of the target nutrient to the consumed amount of the respective target nutrient to obtain a plurality of deviations, wherein each deviation indicates a deficit for the respective target nutrient if the consumed amount of the target nutrient is below the target level of the target nutrient, and an excess for the respective target nutrient if the consumed amount of the target nutrient is above the target level of the target nutrient;

    determine a nutrient coefficient for each target nutrient based on the nutrition-related goal associated with the person, wherein the nutrient coefficient for each target nutrient is indicative of an importance of the respective target nutrient to the person relative to other target nutrients;

    compute a nutritional index that represents an aggregate alignment between the consumed amounts of the plurality of consumed nutrients and the target nutritional profile, wherein the nutritional index is based on a weighted function that applies the nutrient coefficient for each target nutrient to the respective deviation for the target nutrient;

    generate a plurality of food recommendations and a predicted index impact for each of the food recommendations, each food recommendation comprising a recommended food and a specified portion size of the recommended food that if consumed by the person improves an alignment of at least one of the target nutrients and simultaneously reduces a negative impact on an alignment of at least another one of the target nutrients, wherein the predicted index impact for each recommended food is indicative of a predicted change in the nutritional index if the person consumes the recommended food; and

    an output port configured to provide the nutritional index, the predicted index impact for each food recommendation, and the plurality of food recommendations for display by a user interface device, wherein the user interface device is configured to display the plurality of food recommendations in an order determined based at least in part on the predicted index impact associated with each food recommendation.
