![]() However, it is unclear whether replacing red meat with legumes is associated with a reduced risk of hypertension. ĭietary guidelines have emphasized reducing the intake of red and processed meat and replacing these food groups with high-quality plant-based protein sources, such as legumes. However, replacing other animal sources of protein with red meat protein in DASH diet resulted in no more improvement in blood pressure among healthy, and hypertensive subjects. Also, finding from the optimal macronutrients intake (OMNI)-Heart trial which modified the DASH diet by replacing 10% of the carbohydrate with vegetable-based protein indicated a further reduction in blood pressure, compared with the original DASH diet among hypertensive patients. The Dietary Approaches to Stop Hypertension (DASH) diet, which is rich in healthy food groups, was developed to prevent and treatment of hypertension. ĭietary modification can be effective in controlling and preventing diabetes and hypertension. The UK Prospective Diabetes Study showed that among type 2 diabetes patients, a 10 mg reduction in systolic blood pressure reduced the risk of CVD morbidity and mortality by 6–12% in type 2 diabetes patients. The overlap between type 2 diabetes and hypertension markedly increased cardiovascular disease (CVD)-related morbidity and mortality. ![]() Compared with non-diabetic individuals, patients with type 2 diabetes have nearly twice the incidence of hypertension. It is more common in type 2 diabetic patients with a prevalence of 70%. Hypertension is a public health crisis, affecting more than one in four adults globally. In DASH diet, the balance of consumption of refined grains and fruits along with higher vegetable consumption and lower sweet, sodium and energy intake reduced the SBP. The DASH diet, enriched in legumes, could improve SBP in participants with type 2 diabetes. The multivariable RCS analysis showed a U-shaped relationship of refined grains, an L-shaped relationship of fruits, and a linear relationship of sweet, energy, sodium and vegetables intake with SBP. In the legume-based DASH diet, SBP decreased with the legume intake of more than 95.8 g/day ( P nonlinear < 0.001). ResultsĪ reduction in SBP and urinary sodium was observed at week 16 in both dietary interventions, and this reduction was more significant in the legume-based DASH diet, than in the DASH diet. The restricted cubic spline (RCS) was applied to assess the linearity and explore the shape of the relationship between the changes in food groups and systolic blood pressure (SBP) in the two intervention groups. An intention-to-treat approach with multiple imputations of missing data was applied. ![]() Blood pressure and urinary sodium and potassium were measured at baseline and after 16-week interventions. ![]() Participants were randomized to the traditional DASH diet (n = 150) or the legume-based DASH diet (n = 150). We further investigated whether changes in individual dietary food groups in the DASH diet contribute to blood pressure. This study aimed to investigate the effects of legumes in dietary approaches to stop hypertension (DASH) on blood pressure and urinary sodium and potassium in participants with type 2 diabetes.
