Abstract
Unaided tailoring of individual food selections to multiple genotype‐directed nutrient intake targets greatly exceeds the abilities of lay consumers and dietetic professionals alike. Previous draft versions provided proof‐of‐concept for computer‐assisted menu planning (http://www.nim.unc.edu/nutrition/guidance.html). Added functionalities and an expanded food database have now improved usability and consumer choice.The personal target sets depend on user characteristics and genetic data. The user never enters personally identifying information, DNA samples are identified by code.The algorithmic core calculates and ranks the sum of normalized parabolic distance functions relative to personal target sets of individually selectable nutrients and food groups in a potential menu. The program offers an initial choice of well‐matched daily meal plans. The user can then make unlimited modifications by replacing, adding or deleting items. Real‐time displays of color‐coded lists, which show alternative foods ranked by goodness‐of‐fit, make finding acceptable choices easy.Initial user tests indicate that this online tool effectively supports personalized meal planning based on complex genotype patterns.
