Miso

Even a large serving stays well within a ~400 mg working daily purine target.

These are plant purines, which research links far more weakly to flares: the 10 mg here counts as roughly 3 mg toward your gout risk.

Miso is an easy choice to keep on hand.

Why grade A

Low risk in a typical serving. A great everyday choice for a gout-friendly diet.

Per 100 g (for comparison)

Purines Moderate confidence
56.1 mg/100g
LowModerateHighVery high

Moderate for gout (50–150 mg/100g).

Fructose Moderate confidence
6 g/100g
LowModerateHighVery high

Moderate for gout (3–8 g/100g).

Processing: NOVA 3 of 4 (processed food). How processing affects the grade.

These are plant purines. Research links purines from vegetables, legumes, and mushrooms far more weakly to gout flares than purines from meat and seafood, so the per-100g figure overstates the real risk here.

Eating miso as part of a bigger dish? The Dish Decoder grades the whole plate, ingredient by ingredient.

Good to know: FRUCTOSE CONTEXT: Value of 6.0g/100g applies to WHITE/SWEET MISO (shiro miso). The koji process in white miso produces significant residual sugars (short fermentation, high rice content). RED MISO (aka miso) has substantially lower fructose (~1-2g/100g) due to longer fermentation consuming more sugars. MIXED MISO is intermediate. For gout patients, red or mixed miso is the lower-fructose choice. This entry should be treated as white miso. Source: USDA SR Legacy; standard Japanese food composition tables.
