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.
