Mussels are one of the most nutrient-dense things you can pull from the sea, and one of the most sustainable: these glossy blue-black shellfish are farmed with a remarkably light environmental footprint. Lean, mineral-rich and surprisingly rich in omega-3, mussels turn up in research on brain health, energy and performance and heart health.

Why mussels are good for you
Mussels are an exceptional source of vitamin B12, which supports nerve function and the formation of red blood cells, and they deliver well-absorbed haem iron, making them a genuinely useful shellfish for keeping energy levels up. They also provide selenium and zinc for immune and antioxidant defences, plus the long-chain omega-3 fats EPA and DHA more usually associated with oily fish, which are studied for heart and brain health.
Mussels are naturally high in purines, compounds the body breaks down into uric acid, so people managing gout may want to keep portions modest.
Mussels nutrition at a glance
The full breakdown is in the nutrition label above. The headline is a lot of nutrition for very little fat or calorie cost: lean protein, omega-3 and a dense package of minerals. The caveat is sodium and freshness rather than the nutrients themselves, since shellfish are naturally salty and must be very fresh, so they are best enjoyed soon after buying and cooked with care.
How to buy, store and cook mussels
Buy mussels that smell clean and of the sea, with tightly closed shells; discard any that are cracked or that stay open when tapped, as these are not alive. Keep them cold and loosely covered, never sealed in water or an airtight bag, and cook them the same day. Scrub the shells, pull away the wiry beard, then steam them in a covered pan with a splash of liquid for just a few minutes until they open; discard any that stay shut. They are wonderful with garlic, white wine and a thick slice of wholemeal bread, and pair naturally with other shellfish such as prawns.
Common questions
Are mussels good for iron? Yes, they are a strong source of haem iron, the well-absorbed form, making them a helpful food for supporting healthy iron levels alongside foods rich in vitamin C.
How do you know if a mussel is safe to eat? Before cooking, discard any with broken shells or shells that will not close when tapped; after cooking, discard any that have not opened. Cook them thoroughly and eat them very fresh.
