Background <p>The aim of this study was to examine the associations between adherence to theDietary Approaches to Stop Hypertension (DASH) diet, the Mediterranean diet, and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet and metabolic parameters in individualswith Type 2 diabetes mellitus (T2DM).</p> Methods <p>This cross-sectional study was conducted with 90individuals with T2DM. Participants completed a questionnaire form containing sociodemographiccharacteristics, and their anthropometric measurements, biochemical parameters, body compositionanalyses, Visceral Adiposity Index, and nutritional status were evaluated.</p> Results <p>According tomultivariate regression analyses, each 1-point increase in the MIND diet score was found to be inversely +associated with LDL-cholesterol (β = − 0.011), triglycerides (β = − 0.010), and Visceral Adiposity Index (β = − 0.387). Each 1-point increase in the Mediterranean diet score was inversely associated with Body Weight (β = − 0.028), Waist Circumference (β = − 0.058), Visceral Fat Percentage (β = − 0.139), Fasting Blood Glucose (β = − 0.016), and Triglycerides (β = − 0.014). Each 1-point increase in the DASH dietscore was associated with a decrease in fasting blood glucose (β = − 0.007) and triglyceride levels (β =− 0.005; <i>p</i>&lt; 0.01).</p> Conclusion <p>It has been observed that adherence to dietary patterns is associatedwith metabolic parameters in individuals with type 2 diabetes, and adherence to the Mediterranean diethas been found to be associated with a greater number of metabolic parameters compared to otherdietary patterns.</p> Graphical abstract <p></p>
