Sushi is no different from any other type of cuisine. To tackle gout, you have to start from a basically healthy diet. That means avoiding excesses of calories, iron, and animal purines. It does not mean avoiding these completely – just eat a sensible amount. Every person’s needs are different, so you might ask for personal help in the forum. Before you do, I urge you to read my Gout Foods guidelines.
Because of this, there is no specific advice on sushi. However, I did mention sushi in Octopus and Gout. Also, see Gout Foods Table for Fish.
