Spring onion and gout
Verdict: Spring onion is low in purines — you can eat it regularly as part of a gout-friendly diet.
Spring onions are a low-purine vegetable, containing just 10.1 mg of purines per 100 grams in their raw form. This makes them a safe choice for people managing gout, whether you're in daily maintenance mode or recovering from a flare. For context, most health guidelines suggest staying under 400 mg of purines daily during maintenance, so spring onions fit comfortably into your diet without worry. The cooking method makes a small difference: steamed spring onions are slightly lower at 8.1 mg per 100 grams, while roasting increases them to 12.5 mg—but all variants remain in the low range. A practical tip is to enjoy spring onions as part of balanced meals rather than in isolation; their mild flavour works well in salads, stir-fries, or as a garnish. Staying well-hydrated throughout the day remains important for gout management, and low-purine vegetables like spring onions are part of a sustainable eating pattern that supports your overall health.
