Processing: NOVA 1 of 4 (unprocessed or minimally processed). How processing affects the grade.

Good to know: No species-specific purine assay for Pangasius (basa / swai, family Pangasiidae) is published in the purine literature. Value adopted from Cod, Atlantic (110.3 mg/100g, USDA Purine DB 2025) as the nearest MEASURED lean, low-fat white-fish analogue. Pangasius has a comparably lean freshwater-whitefish profile (Fishes 2022, MDPI nutritional profiling of farmed Pangasius). NOT proxied from US channel catfish (Catfish, farmed, 205 mg/100g): despite the shared name, channel catfish (Ictaluridae) is a different, fattier family with atypically high hypoxanthine, and would overstate the risk. Treat it as an estimate. A typical fillet portion lands in the moderate (Yellow / Low Risk) band.

Diet is part of the picture, not all of it

For most people the body makes the majority of its own uric acid. Food contributes the smaller share. Eating well lowers your risk and helps you feel in control, but for many people diet alone does not bring uric acid down enough to stop flares. Medication often does the heavy lifting. Use these grades to make easier daily choices, and work with your doctor on the full plan.

How these numbers work

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. The fructose figure is derived, not a label value: it counts free fructose plus half of sucrose, because sucrose is half fructose and the body treats both the same way. A sucrose-sweetened food therefore carries roughly twice this much total sugar.
