The Surprising Nutritional Profile of Mussels in a Jar
Many consumers view canned or jarred seafood with suspicion, often assuming it to be inferior to its fresh counterpart. However, when it comes to mussels, this is far from the truth. Mussels in a jar, including those canned in oil or brine, retain a significant portion of their impressive nutritional benefits, offering a convenient and accessible superfood. They are particularly noteworthy for their high content of protein, omega-3 fatty acids, and an array of crucial vitamins and minerals, which can support various aspects of your health, from brain function to immunity.
What Makes Mussels So Healthy?
Mussels are celebrated for their rich nutrient density, with some species, like New Zealand green-lipped mussels, containing powerful anti-inflammatory compounds. A single serving provides a substantial amount of high-quality protein, which is essential for muscle repair and growth. They are also a fantastic source of omega-3 fatty acids, particularly the long-chain types EPA and DHA, known for their neuroprotective and cardioprotective effects.
Beyond these macronutrients, mussels are packed with micronutrients that are often lacking in modern diets. For example, they are exceptionally rich in vitamin B12, a nutrient vital for nerve function and red blood cell production. They also offer significant amounts of iron, zinc, and selenium, which contribute to a robust immune system and proper thyroid function.
Potential Downsides and How to Choose Wisely
While the nutritional benefits are clear, it is important to be mindful of how jarred or canned mussels are prepared. The primary potential downsides relate to the additives used for preservation, and your choice of product can mitigate these concerns. Some jarred mussels are packed in oil (often sunflower oil), while others are preserved in a briny liquid that can be high in sodium.
Reading the Label is Key
To ensure you are making the healthiest choice, always check the product label. Look for mussels jarred in extra virgin olive oil for a healthier fat source, or choose options with lower sodium content if you are watching your salt intake. The liquid in which the mussels are preserved can also vary; some are in vinegar-based escabeche, while others are simply in brine. Both are typically safe, but the escabeche might introduce added calories and fats from the oil base.
Another point of consideration is the potential for heavy metal contamination, a risk associated with all seafood due to environmental factors. However, the levels are generally low in farmed mussels, and regulatory bodies closely monitor commercially available products to ensure safety. Still, moderating consumption is always a good practice, especially if you eat a lot of seafood.

Their robust flavor holds up well in sauces and stews. For a simple and healthy meal, you can serve them over a bed of couscous with fresh herbs and a drizzle of lemon juice.

They are a potent source of protein, healthy fats, and essential micronutrients, making them a nutritious and convenient addition to a balanced diet.
