نبذة مختصرة : PURPOSE: Type 2 diabetes is a global health problem. While a healthy diet lowers risk of type 2 diabetes, less is known about diets with low climate impact. This study aimed to investigate adherence to the EAT-Lancet diet and risk of type 2 diabetes in a Danish setting.METHODS: In the Danish Diet, Cancer and Health cohort, dietary data were collected using a validated 192-item food frequency questionnaire, at recruitment in 1993-1997. In total, 54,232 participants aged 50-64 years at baseline with no previous cancer or diabetes diagnoses were included in the current analyses. The EAT-Lancet diet score was used to assess adherence to the EAT-Lancet diet. Participants scored 0 (non-adherence) or 1 (adherence) point for each of the 14 dietary components of the diet score (range 0-14 points). Participants were followed through register linkage until type 2 diabetes diagnosis or censoring. Hazard ratios and 95% confidence intervals (CI) were estimated using multivariable-adjusted Cox regression models.RESULTS: During a median 15-year follow-up period, 7130 participants developed type 2 diabetes. The hazard ratio for developing type 2 diabetes was 0.78 (95% CI 0.71; 0.86) for those with highest EAT-Lancet diet scores (11-14 points) compared to those with lowest scores (0-7 points) after adjusting for potential confounders. After further adjusting for potential mediators, including BMI, the corresponding hazard ratio was 0.83 (95% CI 0.76; 0.92).CONCLUSION: Greater adherence to the EAT-Lancet diet was associated with a lower risk of developing type 2 diabetes in a middle-aged Danish population.
