Evaluation of the Impact of Dietary Education and Intervention on Gout Patients Receiving Urate-Lowering Therapy

The goal of this interventional study is to learn whether dietary education and intervention can reduce blood uric acid levels in patients with gout. The main questions this study aims to answer are: * Can dietary education and intervention reduce gout-related clinical laboratory results? * Can dietary education and intervention improve BMI and SBP/DBP in participants with gout? In this study, participants will be divided into three groups, including a control group, and their outcomes compared, in order to determine whether a low-purine (low-uric-acid) diet and a DASH diet are effective in reducing blood uric acid levels in participants with gout. Participants will: * Participate in the study for a total of 2 years, receiving dietary education and intervention according to their assigned group throughout this period * Complete surveys, physical measurements, and receive dietary education once every 6 months * Receive dietary education by phone and through an app, and complete surveys, once every month
