    Recent evidence shows the beneficial effects of Baltic Sea diet score (BSDS) and healthy Nordic diet index (HNDI) on chronic diseases; however, there is no evidence to investigate them on the risk of type 2 diabetes mellitus (T2DM). The purpose of this study was to investigate the associations between BSDS and HNDI with the risk of T2DM.Methods: This study used a case-control design with participants aged 18 to 60 diagnosed with type 2 diabetes in the last six months (225 cases, 450 controls). The evaluation of BSDS and HNDI employed a validated 168-item semi-quantitative food frequency questionnaire (FFQ). Binary logistic regression was used to determine how OBS and T2DM are related.The mean scores for the BSDS and HNDI were 16.00 ± 2.49 and 11.99 ± 2.61, respectively. The final model, which accounted for confounding variables, indicated that increased adherence to the HNDI is associated with a reduced likelihood of developing T2DM (OR = 0.42; 95% CI 0.18-0.98; p for trend = 0.043). Additionally, a significant association was observed between lower likelihood of T2DM and higher BSDS scores in both unadjusted (OR = 0.49, 95% CI 0.31-0.77; p for trend = 0.001) and adjusted (OR = 0.48, 95% CI 0.32-0.89; p for trend = 0.003) models.Our research shows that following a Nordic diet significantly reduces the risk of T2DM.Commitment to this dietary pattern may also reduce related risk factors. Further longitudinal studies across diverse populations are needed to validate these findings.
