Black beans and gout
Verdict: Black beans is low in purines — you can eat it regularly as part of a gout-friendly diet.
Black beans are a nutritious legume with a purine content of 85.5 mg per 100 g, which falls into the low category. This makes them a reasonable choice for most people managing gout, especially when consumed in moderate portions as part of a balanced diet. During a gout flare, it's wise to be cautious and keep portions small, as legumes do contain purines that your body converts to uric acid. However, during periods between flares, black beans can fit comfortably into your daily eating plan—a typical serving of 150 g cooked beans provides around 128 mg of purines, leaving plenty of room within a daily maintenance target of 400 mg or less. The key is staying hydrated, spacing out purine-containing foods throughout the day, and monitoring how your body responds. Black beans also offer fibre, protein, and minerals that support overall health, so they needn't be avoided entirely.
