Diet and gout… the proof is in the … whatever
DASH diet crushes gout risk
Dr. Jack Cush writing in Rheum Now reported on a study by Choi et al who examined the benefits of the DASH diet. The DASH diet is commonly employed as a dietary means of controlling hypertension.  Like the Prudent diet, the DASH diet has no or low animal protein, but plenty of fruits, vegetables, and low fat dairy products. They compared the incidence of gout in those adhering to either a DASH diet or Western diet and used dietary "scores" to indicate the degree of adherence to either. 
They enrolled 78906 women from Nurses Health Study beginning in 1984. With 22 years of follow-up, there were 778 incident gout cases. Those patients on the DASH diet had 33-40% lower risk of developing gout. Conversely, the Western Diet had a 37-68% higher risk.
