Jerusalem artichoke and gout
Verdict: Jerusalem artichoke is low in purines — you can eat it regularly as part of a gout-friendly diet.
Jerusalem artichoke is a root vegetable with a mild, slightly sweet flavour that is safe to eat regularly if you have gout. At 11.9 mg of purines per 100 g in its raw form, it sits comfortably in the low-purine category—well below the 400 mg daily threshold recommended during maintenance. Even when sautéed (12.3 mg per 100 g) or roasted (14 mg per 100 g), the purine levels remain modest. This means you can include Jerusalem artichoke as part of a balanced meal without worry during gout-free periods. A typical serving of 150 g contributes only about 18 mg of purines, leaving plenty of room for other foods. Boiling and steaming reduce purine content slightly to around 9 mg per 100 g, making these gentle cooking methods ideal if you want to minimise intake further. Pair Jerusalem artichoke with plenty of water throughout the day to support kidney function and help flush uric acid from your body.
