Nutrient-dense sardines offer heart benefits but pose risks for gout and high blood pressure

Sardines are a highly nutritious, affordable seafood option rich in omega-3s, protein, and calcium, but their high sodium and purine content require caution for individuals with hypertension, kidney disease, or gout.
Key points
- Sardines are small, oily fish from the herring family, with various species allowed under the label depending on the country, though their nutritional profiles remain similar.
- The fish are processed quickly after capture, cooked, and canned with liquid to ensure shelf stability and soften bones for consumption.
- Nutritional benefits include high levels of EPA and DHA omega-3 fatty acids, which support heart health and reduce inflammation, along with complete protein and calcium from edible bones.
- Sardines are classified as a 'Best Choice' by the U.S. Food and Drug Administration for children and pregnant women due to low mercury accumulation.
- Health concerns include high sodium content, often ranging from 300 to 500 milligrams per can, and high purine levels that can trigger gout flare-ups.
- Approximately 1% of Americans have a finned fish allergy, though specific sardine allergies are rarer, and individuals with heart or kidney conditions should monitor intake.
