Is calamares high in purines?

Yes: Shellfish red meat and anything else rich in protein as well.

Moderately high: Calamari is moderately high in purines. They are not nearly as high as organ meats, sardines and anchovies, but are moderately high so should be minimized. If gout is stable having moderate portions now and then may be tolerated. A variety of natural remedies can be helpful for gout including vitamin c, Folic Acid and tart cherry juice.
