How many Rolled Oats can I eat with gout?

A typical serving is about 40 g, which delivers 18 mg of purines, or about 4% of a ~400 mg working daily target. There is no need to limit them; a normal portion fits easily in a gout-friendly day.

Are Rolled Oats high in purines?

Rolled Oats are low in purines by weight: about 44.3 mg per 100 g. A typical 40 g serving works out to about 18 mg, or about 4% of a ~400 mg working daily target.

Do Rolled Oats cause gout?

No single food causes gout; it develops from high uric acid over time. Rolled Oats are graded A and are low enough that a normal portion will not meaningfully raise your uric acid.

Rolled Oats

Rolled Oats are low risk in a normal serving and a good everyday choice for most people with gout. A typical 40 g serving has about 18 mg of purines, about 4% of a ~400 mg working daily target.

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 18 mg here counts as roughly 5 mg toward your gout risk.

Rolled Oats are an easy choice to keep on hand.

Good to know: Rolled oats, dry weight. The USDA & ODS-NIH Purine Database does not list oats, so this is inferred, not measured: the value is taken from BARLEY (44.3 mg/100g raw, USDA Purine DB 2025 Table 2), the closest analogue we hold; both are whole cereal grains eaten as a groat or porridge with the bran intact, and bran is where cereal purine concentrates (rice bran measures 100.2 mg/100g against 5.9 for cooked white rice). Confidence is low to flag the inference. Note this basis errs HIGH: barley is the most purine-dense whole grain in our catalogue, and even so a 40 g dry serving of oats works out around 5 mg of effective purine, because plant purines carry a 0.3 source weight. Oats remain a safe, fibre-rich choice for gout.

Source details
Value inferred from food composition or a measured constituent food (for example a related whole food, or USDA FoodData Central sugar data). See the note on this food for the specific basis and figures.
2. Fructose data: USDA SR Legacy, with clinical nutrition literature Evidence tier: Peer-reviewed literature

Source details
USDA SR Legacy nutrient database (fdc.nal.usda.gov); supplemented with published clinical nutrition literature where FDC data unavailable. Used as fallback when FDC API returns no fructose value.

Values are per 100g unless a note says otherwise, rounded to three significant figures; per-serving figures are calculated from the unrounded measurement, so recomputing from the rounded number can differ by a milligram or so. A single determination is normal in food composition tables, not a defect. Last reviewed July 18, 2026.

How we grade foods

Grades combine purine and fructose data with known gout triggers and benefits. We show our confidence on every food.
