Japanese littleneck clams and gout
Verdict: Japanese littleneck clams is moderate purines — eat it in moderation, especially if your uric acid is high.
Japanese littleneck clams are a seafood choice with a moderate purine content of 165.4 mg per 100 g. For someone managing gout, this puts them in a middle category—not off-limits, but requiring thoughtful portion control. During a gout flare, it's wise to avoid them entirely and focus on low-purine foods. However, during stable periods and daily maintenance, a small serving of 100–150 g of cooked clams can fit within a 400 mg daily purine budget, especially if you balance it with plenty of vegetables and whole grains. The key is moderation: think of clams as an occasional treat rather than a regular staple. Staying well-hydrated throughout the day helps your kidneys process purines more effectively, so drink plenty of water alongside any seafood meal. Always listen to your body and track how you feel after eating them.
