Note that this post- hoc analysis of a randomized trial suggested a DASH- style diet might lower serum urate levels. Interestingly, higher sodium intake was also associated with lower serum urate levels. People with hyperuricemia who followed the blood- pressure- lowering DASH diet showed significant decreases in serum urate levels, post- hoc analysis of data from an influential randomized study found. In the Dietary Approaches to Stop Hypertension (DASH) study, participants adhering to the diet, which emphasizes the consumption of vegetables, fruits, and low- fat dairy foods as well as whole grains, poultry, fish, and nuts, had a mean decrease in serum urate levels of - 0. L (9. 5% CI - 0. 6. Stephen P. Juraschek, MD, Ph. D, of Johns Hopkins University, and colleagues. And an even greater urate- lowering effect was seen for participants whose baseline serum urate level was 7 mg/d. L or higher, with a change of - 1. L (9. 5% CI - 2. 5. Arthritis & Rheumatology. That effect size . Hyperuricemia also is recognized as an important risk factor for cardiovascular disease. The original DASH- Sodium study sought to evaluate the effects on blood pressure of this diet compared with a typical American diet, with varying levels of sodium, and found that substantial blood pressure reduction occurred, particularly with low sodium intake. We also hypothesized that reducing sodium intake would lower uric acid levels, given its association with high blood pressure. Participants consumed each of the sodium level diets for 3. This study design allowed within- person comparisons of uric acid levels according to sodium consumption, the team explained. The secondary analysis included 1. More than half were women, three- quarters were black, more than 4. Mean serum uric acid level was 5 mg/d. L. Among those whose baseline serum urate level was less than 5 mg/d. L, no effects were seen for the DASH diet. But for those whose baseline level was 5 to 6 mg/d. L, the reduction in uric acid was - 0. L, and for those with levels of 6 to 7 mg/d. L, there was a reduction of - 0. L. Contrary to expectations, increasing the sodium intake from the lowest level to the medium level decreased serum uric acid by 0. L (9. 5% CI - 0. 5 to - 0. L (9. 5% CI - 0. 6 to - 0. P< 0. 0. 01 for both) for the highest level, the researchers reported. The relationship between sodium intake and uric acid is controversial, yet previous physiologic studies have suggested similar findings. This would suggest that decreased sodium reabsorption in response to higher sodium intake would also decrease urate reabsorption. It is also possible that the inverse relationship between sodium intake and uric acid reflects action of the renin- angiotensin system, as uric acid is inversely related to renal blood flow and vascular resistance. However, sudden changes in uric acid levels (either sudden increases or decreases) can trigger gout flares. Knowing that sodium can cause uric acid levels to fluctuate can help patients and physicians understand more about potential dietary causes of gout flares.
