The Dietary Approaches to Stop Hypertension (DASH) diet lowers serum uric acid (SUA) levels compared to the typical American (control) diet. However, the time required for the DASH diet to take effect is unknown. We analyzed data from a parallel arm, randomized-controlled trial in pre-hypertensive or hypertensive adults (N = 103), comparing the effects of DASH or a control diet on SUA measured at 30, 60, and 90 days. Effects were examined overall and within stratified subgroups based on baseline SUA status (SUA ≥6 mg/dL vs <6 mg/dL). The mean age of participants was 51.5 ± 9.7 years, 55% were women, 75% were black, 42% were obese, and 34% had hypertension. Twenty-four of the 103 (23%) participants had a baseline SUA ≥6 mg/dL. Overall, compared to the control, DASH lowered SUA by 0.5 mg/dL at 30 and 90 days. Among participants with baseline SUA ≥6 mg/dL, DASH lowered SUA by 0.8 and 1.0 mg/dL at 30 and 90 days, respectively. These findings demonstrate that the DASH diet reduces SUA within 30 days, with a sustained effect at 90 days, which is informative for healthcare providers counseling patients on time course expectations for uric acid reduction in response to dietary modification.
