High-frequency data collection can transform our understanding of diets and nutrition

Overview

Diet quality is a critical determinant of human health and serves as a key indicator for food system sustainability . However, data on diets are small, scattered, often project-dependent, without a consistent methodology, limiting actionability (Beal et al., 2021). Contextually sensitive technologies exist that can be implemented to generate sustained and high-frequency data flow from crowds (Gibson et al., 2017Lamanna et al., 2019). Harmonisation of such data collection systems with validated diet quality assessment tools represents a pathway for high-frequency diet quality assessment across scales.
