In March 2020, the COVID-19 pandemic led to a strict lockdown in France for 2 months, drastically changing the daily life of the population. We investigated changes in perceived diet quality and cooking practices during the lockdown in comparison with the preceding period. Between June 9 and 30, 2020, 2422 participants were recruited and completed a questionnaire regarding the evolution of their overall diet and cooking habits during the lockdown. Descriptive analyses showed that 41.5% of participants described dietary changes with a similar proportion reporting positive or negative changes (22.0% and 19.5%, respectively). The exceptional circumstances of the lockdown provided a positive opportunity for some people to improve their diet quality by spending more time cooking (54.8% of those reporting a positive change) or eating more fresh products, including fruits and vegetables (47.4%). By contrast, other participants reported a decline in their diet quality, mainly caused by poorer dietary choices due to the consumption of comfort food (50.3% of those reporting a negative change), snacking (40.1%), or food supply issues (35.9%). The lockdown led to a massive rise in home cooking with 42.0% of all participants cooking more frequently (vs 7.0% cooking less), as barriers such as time constraints were reduced. Using multivariate analyses, we found that this change in cooking frequency varied among population subgroups, especially in regard to financial situation, as individuals in financial difficulty tended to cook less. As home cooking has already been linked to better diet quality and thus health status, our results suggest that the lockdown increased social health inequalities. An adequate public health response is therefore needed to support nutritionally vulnerable populations.
