20 Super Nutritious Fish to Power Up Your Diet

13. Mahi-Mahi - The Tropical Powerhouse

Known for its stunning colours and firm texture, Mahi-Mahi (or dolphinfish – no relation to dolphins!) is a lean, tropical powerhouse. It provides an excellent source of high-quality protein, essential for muscle building and repair, along with significant amounts of selenium, potassium, and vitamin B12. Its flavour is mild and slightly sweet, making it incredibly versatile for grilling, baking, or blackening. Mahi-Mahi holds up well in tacos, sandwiches, or simply served with tropical salsa. As a fast-growing species, it's also often considered a more sustainable choice among larger ocean fish, offering a taste of the tropics with solid nutritional backing.

14. Red Snapper - The Crowd-Pleasing Classic

A favourite in coastal cuisines, Red Snapper is prized for its slightly sweet, nutty flavour and firm, flaky texture. This lean white fish is an excellent source of protein and selenium, a powerful antioxidant that supports immune function. It also provides potassium and vitamin B12. Red Snapper is incredibly versatile; its mildness allows it to absorb marinades and spices beautifully. It shines when baked whole, grilled as fillets, or pan-seared. While ensuring you're getting genuine Red Snapper (mislabeling can occur) is important, this fish is a delicious and nutritious crowd-pleaser, perfect for a healthy, flavourful meal.
