For generations, seafood has been at the heart of the Irish diet. Long before superfoods became fashionable, our coastal communities understood the value of fresh fish and shellfish.
Today, nutrition experts around the world continue to recommend eating fish at least twice a week – and for good reason.
Seafood isn’t just delicious. It’s one of nature’s most nutritious foods.
A Natural Source of High-Quality Protein
Fish and shellfish are packed with protein, which is essential for:
- Building and repairing muscles
- Supporting healthy bones
- Maintaining energy levels
- Keeping us feeling fuller for longer
Unlike many processed protein foods, seafood delivers these benefits while being naturally low in saturated fat.
Rich in Heart-Healthy Omega-3
Perhaps the most talked-about benefit of seafood is its omega-3 content.
Oily fish such as salmon, mackerel, sardines and trout are particularly rich in these essential fats.
Omega-3s are linked to:
- Supporting heart health
- Helping maintain normal brain function
- Supporting eye health
- Contributing to overall wellbeing
Our bodies can’t produce enough omega-3 on their own, so we need to get them through our diet.
A couple of seafood meals each week can make a real difference.
Good for the Brain
There’s a reason people often refer to fish as “brain food.”
The nutrients found in seafood, particularly omega-3 fatty acids and vitamin B12, play an important role in supporting normal brain function throughout life.
Eating fish regularly has been associated with supporting cognitive health and healthy ageing.
A Nutritional Powerhouse
Seafood contains an impressive range of vitamins and minerals, including:
- Vitamin D
- Vitamin B12
- Iodine
- Selenium
- Zinc
- Iron
These nutrients contribute to everything from maintaining healthy bones and supporting the immune system to helping our bodies produce energy.
A Friend to Healthy Eating
Seafood is naturally versatile.
It can be:
- Grilled
- Baked
- Poached
- Pan-fried
- Added to soups, curries and salads
It’s an easy way to create nutritious meals without compromising on flavour.
And with so many different species available, there’s a seafood option to suit every taste and budget.
Don’t Forget Shellfish
Oysters, mussels, prawns and crab are often overlooked when discussing nutrition.
In reality, shellfish are nutritional gems.
For example, oysters are naturally rich in:
- Zinc
- Iron
- Vitamin B12
- Protein
They may be small, but they pack an impressive nutritional punch.
Why Twice a Week?
Health organisations in Ireland and around the world recommend eating fish regularly as part of a balanced diet, including at least one portion of oily fish each week.
Two seafood meals a week is a simple and achievable goal that can help bring a wide range of nutrients to the table.
It doesn’t have to be complicated.
A grilled fillet of salmon, a comforting bowl of chowder, a tray of fresh mussels or a homemade fish pie all count.
A Tradition Worth Keeping
For us at Dorans on the Pier, seafood is more than just food.
It’s part of our heritage.
Since 1961, we’ve had the privilege of helping families discover and enjoy the incredible variety that Irish seafood has to offer.
The sea provides some of the most nutritious ingredients on the planet.
Perhaps that’s why generations of coastal communities have always known what modern science is now confirming:
Eating seafood twice a week is one of the simplest and most delicious ways to support a healthy lifestyle.
So next time you’re wondering what to cook for dinner, why not let the sea inspire you?
Your heart, your brain and your taste buds will thank you for it.
