Fish and seafood
Eat fish and seafood 2–3 times a week as part of a heart-healthy diet.
People who regularly eat fish tend to have a lower risk of heart disease and stroke. Fish and seafood provide protein, selenium, zinc, iodine and vitamins A and D as well as omega-3 fats.
What to choose
Fish and seafood contain omega-3 fats which help to maintain good general health and reduce the risk of heart disease and stroke.
The fish highest in omega-3 fats include:
- blue-eye trevalla
- blue mackerel
- canned sardines, canned salmon and some varieties of canned tuna.
Other fish and seafood that are good sources of omega-3 include barramundi, bream, flathead, squid, scallops and mussels.
The benefits of eating fish far outweigh the risk of the small amounts of mercury contamination.
Mercury is found in the environment, and accumulates in fish and seafood which we then eat.
At high levels mercury can be toxic, but the good news is you can safely eat the fish and seafood listed above without consuming high levels of mercury. Fish and seafood that can be high in mercury include orange roughy (deep sea perch), catfish, shark (flake) and billfish (swordfish/broadbill or marlin).

How much to eat
Eat 2–3 serves of fish (including oily fish) or seafood every week.
A serve of fish is 100–150 g or about the size of your whole hand.
Fish and seafood are protein foods. Aim for 1–3 serves of protein foods each day (lean meat, poultry, fish, eggs, nuts and seeds or legumes). Find out more about serves of protein foods
