How much can I eat?
A typical serving is about 140 g, which delivers 38 mg of purines, or about 9% of a ~400 mg working daily target.
Fructose raises uric acid whatever it comes from, and this serving carries enough of it to count. The trials that found no effect from fruit tested ordinary portions under controlled energy intake, not large ones.
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 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 38 mg here counts as roughly 11 mg toward your gout risk.
Red or green Grapes fit in moderation, so portion is the thing to get right.
