Coconut Water

Coconut Water is low risk in a normal serving and a good everyday choice for most people with gout. A typical 240 g serving is essentially purine-free.

General information, not a substitute for advice from your doctor or dietitian.

This purine value is inferred, not measured directly for this food. See the sources note below for how it was derived.

There is a little fructose here. Fructose raises uric acid whatever its source, but at this amount it is a minor contributor next to the purine number above.

How we count fructose

This is the fructose, not the total sugar: it counts free fructose plus half of sucrose, so a sucrose-sweetened product carries roughly twice this much sugar overall.

Evidence: Ayoub-Charette et al., J Nutr 2021 (fructose by food source) · White et al., Am J Clin Nutr 2018 (whole apple vs. a fructose drink, matched dose)

Even the largest serving here stays under half a day's purines.

Why grade A: per 100 g and processing

Per 100 g (for comparison)

Purines Estimated
0 mg/100g
LowModerateHighVery high

Low for gout (< 50 mg/100g).

Fructose Estimated
1.3 g/100g
LowModerateHighVery high

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

Processing: Unprocessed or minimally processed, NOVA 1 of 4. How processing affects the grade.

Good to know: Packaged or fresh coconut water, unsweetened. Comprehensive purine databases (USDA/ODS-NIH Purine DB 2025 and Japanese gout tables) list no measurable purine for it. Its natural sugars are glucose and fructose, not the uricogenic purine bases. Value set to 0 mg/100g. Sweetened or flavored versions add sugar.
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.
