Oily fish are fish that contain at least 10% fat, most of which are the healthier omega-3 oils. In Australia, the oiliest fish include: canned salmon and sardines, some varieties of canned tuna, salmon, gemfish, blue-eye trevalla, blue mackerel, oysters and arrow squid.
Healthy Heart and Brain
Our bodies don't produce omega-3 fatty acids so we must get them through the food we eat. Omega-3 fatty acids are found in every kind of fish, but are especially high in fatty fish. Some good choices are salmon, trout, sardines, herring, canned mackerel, canned light tuna, and oysters.
Wild Alaskan salmon, oysters and sardines are highest in healthy fats; white fish such as cod or flounder tend to be leaner. White meat has slightly less saturated fat than dark. Turkey is fairly comparable to chicken in nutrients, but both its dark and white meat are slightly leaner.
Because of their many nutritional benefits, prawns are considered by a variety of health experts to be among the healthiest foods in the world. Prawns are a great source of high quality protein, and provide some of the most important vitamins and minerals that make up a healthy diet.
“For most individuals it's fine to eat fish every day,” says Eric Rimm, professor of epidemiology and nutrition, in an August 30, 2015 article on Today.com, adding that “it's certainly better to eat fish every day than to eat beef every day.”
Salmon. Salmon is full of Omega-3, a fatty acid known to be highly beneficial to the brain—Omega-3 provides more oxygen to the brain, and allows us to retain new information, while still remembering old information. The best fish to eat for brain health are salmon, tuna and herring.
The fish with the highest mg of Omega-3 fatty acids are anchovies, herring, mackerel, oysters, and so many others!
Is barramundi healthier than salmon? Salmon and barramundi are both great options as part of a healthy lifestyle! While barramundi has half the calories of Atlantic farmed salmon, both fish are high in omega-3 fatty acids, which play a vital role in brain and heart health.
Packed with nutrients for a healthier you
With half the calories of salmon, Barramundi is still packed with Omega-3 fatty acids (known to promote both brain and cardiovascular health) and boasts 21 grams of lean protein in a four-ounce serving.
White fish
Good choices include King George whiting, flathead and snapper. Plus: It's official – all Australian fish species have now been analysed and every variety has enough omega-3s to be a 'good source'.
Halibut, grouper, mahi-mahi, albacore tuna and canned tuna fall under the FDA's “good choices” category and should be eaten no more than once a week. Swordfish, orange roughy and bigeye tuna are best avoided, as they contain the highest levels of mercury.

What are the foods that fight memory loss? Berries, fish, and leafy green vegetables are 3 of the best foods that fight memory loss. There's a mountain of evidence showing they support and protect brain health.
Research shows that the best brain foods are the same ones that protect your heart and blood vessels, including the following: Green, leafy vegetables. Leafy greens such as kale, spinach, collards, and broccoli are rich in brain-healthy nutrients like vitamin K, lutein, folate, and beta carotene.
While they are both excellent sources of protein and add to your nutrient profile, the benefits of fish tend to be slightly higher than chicken, especially when it comes to the Omega-3 content in it.
Frozen fish is just as nutritious as fresh fish, according to the Natural Fisheries Institute. For fish that is properly frozen right after harvest, like our barramundi, the nutritional value, moisture, and taste is completely preserved.
Australian wild prawns have naturally high levels of many nutrients which contribute to a healthy lifestyle. They are a good source of Omega 3, Phosphorous, Selenium and sometimes Iodine. Prawns are even lower in calories and fat than chicken yet with much more protein.
Avocados contain several nutrients including carotenoids, monounsaturated fats, potassium, and fiber that have been associated with a reduced risk of chronic diseases, especially when included as part of a balanced nutritious diet.
Tomatoes are low in calories and provide important nutrients like vitamin C and potassium. They're also rich in antioxidants—one called lycopene, responsible for tomatoes' characteristic color, is linked to several benefits, such as a reduced risk of heart disease and certain cancers.
