The rapid expansion of food and nutrition information requires new ways of data sharing and dissemination. Interactive platforms integrating data portals and visualization dashboards have been effectively utilized to describe, monitor, and track information related to food and nutrition. Yet, a comprehensive evaluation of emerging interactive systems is lacking. We conducted a systematic review on publicly available dashboards using a set of 48 evaluation metrics for data integrity, completeness, granularity, visualization quality, and interactivity based on four major principles: evidence, efficiency, emphasis, and ethics. We evaluated 13 dashboards, summarized their characteristics, strengths, and limitations, and provided guidelines for nutrition dashboard development. We applied mixed effects models to summarize evaluation results adjusted for inter-rater variability. The proposed metrics and evaluation principles help to improve data standardization and harmonization, dashboard performance and usability, broaden information and knowledge sharing among researchers, practitioners, and decision-makers in the field of food and nutrition, and accelerate data literacy and communication.

The rapid development of nutrition science is embracing digital transformation to generate large amounts of data. The Precision Nutrition and “Big Data” places increasing demand for data repositories and visualization, which enhances the digital transformation. We defined the need for an integrated nutrition data platform as a web-based platform that can collect, store, track, analyze, monitor, and visually display key metrics in nutrition and health while allowing users to interact with visuals and download data provided in the platform. Interactive dashboards create new opportunities for scholars and practitioners to generate and test hypotheses. We are presenting the development and implementation of the Global Nutrition and Health Atlas (GNHA: https://sites.tufts.edu/gnha/), an open access online platform covering nutrition and health data with 26 themes and 500 + indicators from 190 + countries up to 30 years. We view GNHA as an interactive tool aiming to share information and perspectives and foster collaborations and innovations.
