Like Marmite, raw tomatoes and coriander, fish is one of those polarising foods – there are the lovers, and then there are \u201cnot a fish person\u201d people who make an involuntary soured face when you suggest a seafood restaurant or recipe. <\/p>\n

Fair enough, but if you’ve got a hater in your family or circle of friends, there’s a decent chance they simply haven’t met their BFF (Best Fish Friend) yet. Many don’t taste at all “fishy” points out Valerie Agyeman, RD, a women\u2019s health dietitian and founder of Flourish Heights<\/a> virtual nutritional counselling service. Incorporating a mild fish into pasta, pizza or tacos can open picky eater’s minds. “I find that adding seafood to favourite foods is always a great idea,” says Agyeman.<\/p>\n

And it’s worth experimenting, because fish \u201cis packed with vitamins and nutrients that can lower blood pressure and help reduce the risk of a heart attack or stroke,\u201d says Grace Derocha<\/a>, a national spokesperson for The Academy of Nutrition and Dietetics. These include omega-3 fatty acids, vitamins D and riboflavin, calcium, iron, zinc, magnesium and potassium. Never mind that health orgs such as the NHS recommend that we eat two portions of fish a week. \u201cFish is a high-quality, lean protein to add to your eating routine for healthy muscles, bones, tissue and skin,\u201d she says. <\/p>\n

That said, some people nix fish because of concerns about sustainability, or a fear of consuming mercury, a neurotoxin that are especially bad for pregnant women and young children, which can be an issue in larger fish. Most types of commonly sold fish are healthy to eat a few times a week, however. “It\u2019s always best to look for sustainable seafood certifications, including MSC to ensure a safe, healthy and accountable seafood supply,\u201d says Agyeman. <\/p>\n

The NHS<\/a> says women who are or might become pregnant should avoid: <\/p>\n

1. SALMON\"healthiest<\/p>\n

Salmon is a super popular fish, and the fat in this oily fish (especially wild-caught salmon) is the \u201cgood\u201d kind, and has lots of calcium and vitamin D, says DeRocha. \u201cThis is because wild caught salmon is found in its natural habitat and hence is less exposed to contaminants and processed fish food,\u201d she says. <\/p>\n

2. TUNA\"healthiest<\/p>\n

You can\u2019t beat tuna for everyday convenience: Rip open a pouch or a single-serve can and toss it in your salad for a quick lunch. \u201cTuna is rich in omega-3 fatty acids, vitamin D, and selenium – a mineral that acts as a powerful antioxidant in the body,\u201d says Agyeman. \u201cAntioxidants protect the body from oxidative stress and damage to your cells.\u201d Don\u2019t let tuna be your only fish, however, because most species have a high mercury content, points out Derocha. In general, bigger varieties (of any fish) contain more, and when it comes to tuna, that means going easy on yellowfin, ahi tuna and albacore. \u201cInstead, opt for smaller species like the skipjack, which is the chunky tuna in a can,\u201d she says.

3. COD\"healthiest<\/p>\n

Cod is a great fish to serve to newbies, says Derocha. \u201cIt has a milder flavour that picky eaters and kids could enjoy.\u201d It\u2019s so universally loved that it\u2019s often used in fish and chips (yum!), and when grilled or baked, cod is low in fat and naturally rich in protein. <\/p>\n

4. SARDINES\"healthiest<\/p>\n

Sardines are not a good starter fish, because, well, they’re “fishy.” These little fish have a strong taste, but they are excellent for you, says Agyeman. \u201cSardines have tiny, edible bones that provide a great dairy-free source of calcium,\u201d she says, and have iron and selenium as well. \u201cSardines and crackers are one of my favourite midday snacks to keep me feeling satiated and get an energy boost.\u201d They\u2019re also good over pasta in tomato sauce, or with lemon and garlic. <\/p>\n

5. HALIBUT\"healthiest<\/p>\n

\u201cHalibut is a firm, white fish with a rather mild flavour,\u201d says Derocha, and so one that\u2019s kid friendly (try it grilled or using it for fish sticks). It\u2019s a good source of selenium, phosphorus, magnesium, and vitamins B6 and B12. <\/p>\n

6. UNAGI (A.K.A. EEL)\"healthiest<\/p>\n

Unagi is much-loved in Japan, and loaded with vitamins and minerals, protein and other key nutrients. \u201cUnagi is also believed to have the highest amount of unsaturated fatty acids than any other sea creature – the omega-3 fatty acid in unagi could help improve blood pressure, lower cholesterol, and help maintain bone health,\u201d says Derocha. \u201cThis and vitamin A are believed to reduce wrinkles and keep the skin supple as well.\u201d Look for Japanese unagi, specifically.<\/p>\n

7. OYSTERS\"oysters<\/p>\n

As if you needed an excuse to test whether this shellfish is, in fact, an aphrodisiac! Oysters are not for beginners, but the salty, slimy slurp is a treat that have regulars racing to the raw bar. \u201cOysters contain a rich amount of zinc, which supports your body\u2019s ability to fight off colds, viruses, and other bugs that make you sick,\u201d says Agyeman. Or try cooking them, says Derocha, perhaps in a stew. They are also great for the environment. \u201cThe shells are an excellent source of calcium, which when used in the garden can help build strong plant barks as well as balance the soil pH,\u201d she adds.<\/p>\n

8. HERRING\"healthiest<\/p>\n

These silvery fish are not only affordable and full of omega-3s, but herring has minimal mercury content, making it one of the cleanest and safest ocean fish to eat, says Derocha. \u201cHerring is an excellent source of vitamin D – for people who don’t get enough sunlight, herring could be an ideal solution to keep your body at recommended levels of vitamin D.\u201d <\/p>\n

9. PRAWNS\"healthiest<\/p>\n

Prawns belong in your tacos, any day of the week. Okay, it is not a fish so much as a crustacean, but “prawns are high in protein and it has a light flavour that kids and adults can enjoy any time of day,\u201d says Agyeman. \u201cIt\u2019s also a great source of iodine and selenium, which supports a healthy thyroid and proper metabolism.\u201d While not as high in omega-3 fatty acids as some other choices, they are low in mercury and calories and high in protein. <\/p>\n

10. SCALLOPS
\"healthiest<\/p>\n

These shellfish have a pleasing texture and delicate flavour. Once shucked (which is how scallops are usually sold), they are simple to prepare, says Derocha. \u201cJust be careful not to overcook them, which is easy to do – all it takes is a quick sear in a super-hot pan for them to be cooked to perfection.\u201d Low in mercury, they\u2019re ranked as sustainable in a variety of wild and farmed varieties, she adds. They’re also a good option for picky eaters, says Agyeman. <\/p>\n

11. CLAMS \"baked<\/p>\n

Agyeman favours these shellfish for their abundance of vitamin B-12, essential for healthy blood cells, nerves and brain function, she says. Derocha agrees. \u201cOne of the best benefits of clams is that their proteins provide several essential amino acids. These are amino acids that the human body cannot make, and therefore must be obtained from dietary sources. A serving of clams provides over 100 % of the recommended daily intake of 11 different amino acids,\u201d including all nine essential ones. <\/p>\n

12. CRAB\"alaskan<\/p>\n

It has a fancy reputation, but there\u2019s no need to save it for special occasions. \u201cDepending on the variety, crab ranges from 80 to 100 calories per 85g serving and offers up 16 to 20 grams of protein, plus 350 to 400mg of omega-3 fatty acids,\u201d she says. As far as sustainability goes, crab is a \u201cbest choice.\u201d<\/p>\n

13. POLLOCK \"beer<\/p>\n

Pollock is primarily caught along the western and southern coastlines of the British Isles and because of its mild flavour and light texture, it\u2019s the most-used type in fish sticks and other battered fish products that kids love. It\u2019s also one of the more affordable, says Derocha, and naturally adopts the flavours of marinades and spices, so is good in lots of dishes. \u201cBut the shining star of Alaska Pollock is the omega-3s that it provides -between 50-1,000 milligrams of omega 3s per serving,\u201d she adds. <\/p>\n
