The dietary modifications were more effective in reducing both SBP and DBP vs. control diet .
The Low-sodium , High-fiber , DASH , Low-fat , Low-protein and Vegan dietary approach were significantly more effective in reducing SBP compared to a control diet .
The High-fiber , Low-fat , Low-protein and Vegan diet were significantly more effective in reducing DBP .
The Low-sodium and High fiber diets had the greatest lowering effect on SBP and DBP in T2D patients .
CONCLUSIONS Adopting healthful dietary modifications were more effective in reducing both SBP and DBP vs. control .
The High-fiber and Low-sodium diets had the greatest lowering effect on SBP and DBP in T2D

Investigating the effect of DASH diet on blood pressure of patients with type 2 diabetes and prehypertension: Randomized clinical trial.
BACKGROUND AND OBJECTIVES Prehypertension in people with type 2 diabetes is associated with increased risk of cardiovascular disease and lower extremity damages compared to people with normal blood pressure . On the other h and , limited studies have conducted to investigate the effect of DASH diet on blood pressure and prehypertension in patients with type 2 diabetes . Therefore , in this study , we aim ed to evaluate the effect of DASH diet on blood pressure and prehypertension in patients with type 2 diabetes . MATERIAL S AND METHODS In this clinical trial , 80 patients with diabetes type 2 and prehypertension in the age range of 18 - 65 years were r and omly allocated to intervention ( n = 40 ) and control ( n = 40 ) groups for 12 weeks . The intervention group had DASH diet and the control group received diabetic diet in accordance with the recommendations of the American Diabetes Association ( ADA ) with 24-h dietary recall ; systolic and diastolic blood pressures were measured before and after study . RESULTS Taking DASH diet and diabetic diet for 12 weeks caused significant reduction in systolic blood pressure in the intervention group ( P value = 0.003 ) . Diastolic blood pressure showed no significant change in none of the two groups . CONCLUSION Following the DASH diet in patients with prehypertension has beneficial effects in improving systolic blood pressure and can be effective to prevent the development of hypertension . Hence , there are needs for long-term interventions with larger sample size in future studies
