Which canning preparation method retains fewer beneficial omega-3 fatty acids compared to tuna packed in oil?

Answer

Packed in water

Tuna that is canned and packed in water is the leaner option regarding overall fat content. While this means lower total calories, the beneficial omega-3 fatty acids are fat-soluble and thus are retained in lower quantities in the water medium compared to tuna packed in oil. Tuna packed in oil absorbs some of the surrounding oil, increasing its total fat and consequently its intake of omega-3s, although the type of oil dictates the overall fat profile quality.
