Adherence to the EAT–Lancet Diet: Unintended Consequences for the Brain?
Study answer

Adherence to the EAT-Lancet diet (WISH) showed small or nonsignificant effects on HRV and cognition, but was associated with lower depressed mood and better focused attention after covariate adjustment. Adherence to AHEI showed stronger associations with higher HRV, better mood, and improved episodic memory. Cluster analysis within the top tertile of EAT-Lancet adherence identified two patterns: Balanced (cluster 1) and Restricted (cluster 2). Cluster 2 characterized by limiting red meat/poultry and lower fish/unsaturated fats had poorer nutrient adequacy (folate, selenium, zinc, iron,…
