WEDNESDAY, Aug. 13, 2025 (HealthDay News) — A modified version of the Dietary Approaches to Stop Hypertension (DASH) diet is effective at lowering glucose in adults with type 2 diabetes, according to a study published online Aug. 5 in Nature Medicine<\/em>.<\/p>\n Michael Fang, Ph.D., from Johns Hopkins University in Baltimore, and colleagues conducted a crossover trial in which 89 adults with type 2 diabetes were assigned to four isocaloric diets in a random order: the DASH4D diet (a DASH-style diet tailored for diabetes) or a comparison (typical American) diet, each with higher (3,700\u2009mg\/day at 2,000\u2009kcal) or lower (1,500\u2009mg\/day at 2,000\u2009kcal) sodium, with each lasting five weeks.<\/p>\n The researchers found that the DASH4D (versus comparison) diet significantly reduced mean glucose (mean difference,\u2009\u221211.1\u2009mg\/dL) and increased time in range (mean difference,\u2009+5.2 percentage points). There was no effect on the coefficient of variation. For secondary outcomes, glucose standard deviation and time spent with hyperglycemia (glucose >180\u2009mg\/dL <\/sup>and >250\u2009mg\/dL) were lower in the DASH4D diet. However, time spent with hypoglycemia (glucose <70\u2009mg\/dL and <54\u2009mg\/dL) was similar across diets. No serious adverse events related to continuous glucose monitoring or the study diets were reported.<\/p>\n \u201cThe original DASH diet has long been recommended for people with diabetes and other health conditions due to its effectiveness in lowering blood pressure, but this is the first time a controlled study has shown a significant improvement in glucose control as well,” senior author Elizabeth Selvin, Ph.D., also from Johns Hopkins, said in a statement.<\/p>\n Abstract\/Full Text (subscription or payment may be required)<\/a><\/p>\n
