The Association between the EAT-Lancet Diet and Diabetes: A Systematic Review

Several studies have explored the association between diabetes and the EAT-Lancet diet. Thus, the objective of our study was to conduct a systematic review to analyze and summarize all clinical studies concerning the association between diabetes and the EAT-Lancet diet. We undertook a comprehensive search of the Embase, Cochrane, and PubMed databases up to 15 August 2023. All clinical studies concerning the association between diabetes and the EAT-Lancet diet were summarized and analyzed. In total, our systematic review included five studies of four prospective studies and one cross-sectional study, encompassing 259,315 participants. All the included studies were evaluated as high quality. The outcomes from all studies indicated that adherence to the EAT-Lancet diet was correlated with a reduced risk of diabetes. In conclusion, the EAT-Lancet diet may be an effective dietary intervention for diabetes. Nevertheless, the number of studies examining the association between diabetes and the EAT-Lancet diet is limited. Further high-quality studies are required to expand our understanding of the benefits of the EAT-Lancet diet for patients with diabetes.
