Summary
Brief summary
This is three-month study of milk products for prevention of gout attacks. Patients with recurrent gout attacks will be randomized to three separate milk powder arms; each product will be administered daily as a 250ml milk drink. The three groups will be a control milk product, a standard skim milk powder, and a skim milk powder enriched with anti-inflammatory factors. We will analyse whether any of the products tested reduces the frequency of gout attacks.
