Miso Soup
With moderationMiso soup is a low-purine, fermented soybean broth that can fit a gout-friendly diet in moderation. Its high sodium content is the main concern.
- Low in purines compared with meat-based broths and organ meats
- Hydrating and warm, which supports fluid intake for uric acid clearance
- Fermented soy may offer protein without the purine load of animal sources
- High sodium can worsen blood pressure and kidney strain, both linked to gout risk
- Dashi and some instant versions may contain bonito flakes or fish extracts, which are high in purines
- Instant packets can be very salty, so portions add up quickly
Overview
Miso soup is typically made from dashi stock, fermented soybean paste (miso), tofu, seaweed, and green onion. Most of its ingredients are low in purines, which makes it a generally reasonable choice for people managing gout [1].
Purine Considerations
Traditional dashi is often brewed from katsuobushi (dried bonito) or kombu. Bonito is a fish with a relatively high purine content, so bonito-based dashi adds purines to the bowl. Kombu-based or vegetable dashi avoids this issue. Tofu and seaweed are low in purines and are good additions [2].
Sodium
The main drawback is sodium. Miso is heavily salted, and a single bowl can contain a substantial share of the recommended daily limit, especially with instant preparations. High sodium intake is associated with elevated blood pressure and reduced kidney function, both of which can raise uric acid levels and gout risk [3].
Practical Tips
Choose kombu or vegetable dashi when possible, use smaller servings, avoid adding extra salt, and pair the soup with plenty of water. Homemade versions allow better control over sodium and stock ingredients.
