Lower-purine seafood
Why the numbers vary
The seafood measured here run from 7.7 mg to 1399.7 mg per 100 g, so the category is a poor guide on its own — which specific food, and prepared how, decides almost everything.
Preparation matters more than the food's name. Oyster measures 282 mg, while Oyster measures 193 mg — a difference of 89 mg. Drying and grilling remove water and concentrate what is left; boiling can move purines into water that is then poured away.

Questions about oysters and purines
Is oysters high in purines?
Median 242 mg per 100 g, oysters falls in the very high band (200–300 mg per 100 g) on the six-level scale used across this site. Individual measurements range from 193 to 282 mg.
How many purines are in a serving of oysters?
It depends entirely which preparation. Compared at the same 150 g: about 290 mg for oyster, about 423 mg for oyster. That upper figure is a like-for-like comparison rather than a serving — dried and concentrated foods are normally used by the spoonful, so their per-100 g value is the fairer read. The table on this page lists both for every preparation measured.
Does cooking change the purine content of oysters?
Substantially. In this database Oyster measures 282 mg while Oyster measures 193 mg per 100 g. Drying and grilling concentrate purines by removing water; boiling can leach some into the cooking liquid.
