Canned Tuna

Overview

Canned tuna is a convenient, protein-rich fish, but it is a moderate-to-high purine food. Purines are broken down into uric acid, and elevated uric acid is the underlying driver of gout flares [1].

Purine Content

Fish varies widely in purines. Canned light tuna (skipjack) generally contains less purine than albacore, which is sold as "white" tuna and is closer to fresh tuna in purine content [1][2]. Fish with higher purines, such as sardines, anchovies, and mackerel, are typically considered less suitable during flares [2].

Other Considerations

Tuna's omega-3 fatty acids are beneficial for overall cardiovascular health, which is relevant because people with gout often have higher cardiovascular risk [3]. Check labels for sodium content, since salted or flavored tuna can add to fluid retention and blood pressure concerns. Packing in water is usually preferable to oil.

Practical Guidance

Most people with gout can include canned light tuna occasionally in normal portions, roughly a few servings per week, while limiting albacore. During an acute flare, it may be wise to avoid fish high in purines until symptoms settle. Pairing fish with plenty of vegetables, whole grains, and water supports better uric acid control. Alcohol should be avoided alongside fish meals, since it increases uric acid production and reduces its excretion [1].
