Abstract

Purpose

This literature scoping review aims to investigate if, how and why eating behaviours change after a crisis event such as a natural disaster, financial crisis or pandemic in high-income countries.

Design/methodology/approach

The COVID-19 pandemic and resulting “lockdowns” and social distancing measures have changed access to food, the types of food consumed and usual eating behaviours. Early research on the effect of the COVID-19 pandemic is compared with existing literature on other high-impact crises in high-income countries around the world, such as Hurricane Katrina and the Global Financial Crisis. A search of four electronic databases in August 2020 of literature from 2000 to 2020 yielded 50 relevant publications that were included in the qualitative thematic analysis.

Findings

The analysis found that crisis events made accessing food more difficult and led to increased food insecurity. Home cooking, sharing food and eating together (within households during the pandemic) all increased during and after a crisis. Resources often reduced and needed to be pooled. Crises had a multi-directional impact on dietary patterns, and the motivators for dietary pattern change differ between populations and crises.

Originality/value

In conclusion, eating behaviours impacted by crises because of the disruption of food systems, increased food insecurity and changes in daily routines. Community networks were a strong protective factor against adverse outcomes from food insecurity.
