In a recent study published in Nature Communications , researchers determined the association between EAT-lancet dietary adherence and incident anxiety and depression. In the present study, researchers investigated whether adhering to the EAT-Lancet diet could lower anxiety and depression incidence among 180,446 United Kingdom Biobank participants. The study included UK Biobank members who have completed an online 24-hour food recall questionnaire at least once.
Exclusion criteria included withdrawal, anxiety or depression, anxiolytic usage, and abnormal total energy intakes (below 500 or more than 3,500 kcal/day in females, below 800 or more than 4,000 kcal/day in males). The researchers utilized the Oxford WebQ to obtain dietary data from the remaining 70,000 individuals, who completed four more online questionnaires at 3–4 monthly intervals between February 2011 and April 2012, based on a 24-hour food recall from the preceding day. They used the EAT-Lancet diet index to assess adherence to the EAT-Lancet Commission's recommendations for healthy diets derived from sustainable food systems.
They used three diet scores, i.e., the Knuppel index, the Kesse-Guyot index, and the Stubbendorff index, to analyze the link between EAT-Lancet diet adherence and anxiety and depression.
The researchers tracked the subjects from baseline until outcome occurrence, death, or the last follow-up date (March 23, 2021), whichever came first. They determined illness outcomes using self-reporte.
