Crawfish (crayfish)

Crawfish (crayfish) is fine in moderation. Watch your portion size, especially during a flare. A typical 85 g serving has about 100 mg of purines, about 25% of a ~400 mg working daily target.

Why grade C: per 100 g and processing

Per 100 g (for comparison)

Purines
118 mg/100g
LowModerateHighVery high

Moderate for gout (50–150 mg/100g).

Fructose
0 g/100g
LowModerateHighVery high

Low for gout (< 3 g/100g).

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

Good to know: Mean of three seasoned ready-made crayfish products (thirteen-spice, garlic and spicy), tail meat 99.9, 108.6 and 144.6 mg/100 g. Plain boiled crayfish has not been measured, so treat the figure as a good estimate for crawfish as eaten. The roe measured 84.5 to 173.3 mg/100 g.
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.
