From Tide to Table: Why Blue Foods Are the Future of Healthy Travel (and Everyday Eating)
As a dietitian and travel advisor, I’m always looking for foods that tell a story - foods that connect culture, health, and the environment. Lately, I’ve been diving deeper into what’s known as “blue foods”, and they might just be one of the most exciting (and underrated) parts of both global cuisine and sustainable nutrition.
If you’ve ever enjoyed fresh oysters on the coast, a steaming bowl of mussels in a seaside village, or seaweed in a nourishing broth while traveling, you’ve already experienced the magic of eating from the ocean.
These foods aren’t just delicious - they’re incredibly powerful for your health and the planet.
What Are Blue Foods?
Blue foods also called aquatic foods come from oceans, rivers, and lakes. The stars of this category include:
Bivalves: clams, mussels, oysters, and scallops
Seaweeds: nori, kelp, wakame, dulse, and more
These foods have been staples in traditional diets around the world for thousands of years. Yet many people still feel unsure about how to buy, cook, or enjoy them.
That’s where things get exciting - because once you understand them, they’re surprisingly simple to incorporate into your everyday meals.
Why Blue Foods Are a Nutrition Powerhouse
From a dietitian’s perspective, blue foods check all the boxes:
High-Quality Protein
Clams, mussels, and scallops provide 15–20 grams of protein in just a 3-ounce serving.
Omega-3 Fatty Acids
Mussels and oysters are rich in heart-healthy omega-3s, supporting cardiovascular health.
Micronutrient Density
These foods are packed with nutrients many people don’t get enough of:
Vitamin B12
Iron
Zinc
Selenium
Iodine (especially important for thyroid health)
Seaweed = Functional Nutrition
Seaweed brings unique benefits:
One of the best natural sources of iodine
Rich in antioxidants and bioactive compounds
Naturally enhances flavor with umami (a great way to reduce added salt)
The Sustainability Story (This Is Where It Gets Really Interesting)
If you care about the environment, even a little, this is where blue foods shine.
Bivalves are one of the most sustainable animal proteins on the planet.
They:
Require no feed (they eat naturally occurring plankton)
Improve water quality by filtering it (an oyster can filter up to 50 gallons a day!)
Have a carbon footprint similar to plant-based proteins
Seaweed is even more impressive:
Requires no land, freshwater, or fertilizers
Absorbs carbon at incredibly high rates
Helps restore marine ecosystems
In a world where we’re constantly trying to eat “better,” blue foods offer a rare win-win:
👉 Better for your body
👉 Better for the planet
A Travel Perspective: Eat Like the Blue Zones (and Coastal Cultures)
One of my favorite ways to experience a destination is through its food, and blue foods are deeply rooted in many of the world’s healthiest cultures.
Think:
Mediterranean coastal villages with fresh seafood
Japanese cuisine rich in seaweed and ocean flavors
Nordic and island communities that rely on shellfish
These regions often align with longevity-focused eating patterns, where seafood is enjoyed regularly but simply.
It’s not about complicated recipes, but rather fresh, flavorful, and minimally processed meals.
“But I Don’t Know How to Cook That…”
I know, right? It’s not in the American culture. But, you can teach an old American new tricks. I promise, it’s easier than you think.
Here are a few simple ways to start:
Toss mussels or clams into pasta with garlic and olive oil
Add canned oysters or smoked mussels to toast for a quick protein boost
Stir seaweed into soups or grain bowls
Try a simple seafood boil at home (it’s easier than it sounds!)
Most fresh bivalves cook in under 10 minutes. Yes, really!
Smart Tips for Getting Started
If you’re new to buying seafood, here are a few quick wins:
Choose shells that are tightly closed (or close when tapped)
Look for a fresh, ocean-like smell - not fishy
Store in the fridge and use within 1–2 days
Don’t overthink it - simple preparation is best
And don’t overlook frozen or canned options. They’re affordable, convenient, and still highly nutritious.
Bringing It Home (or Into Your Next Trip)
Whether you’re planning your next getaway or simply trying to eat healthier at home, blue foods are an incredible place to start.
As someone who helps clients build healthier lifestyles and plan meaningful travel experiences, I love weaving food into both.
Because food isn’t just fuel - it’s connection.
To culture.
To place.
To the planet.
And sometimes, the most powerful changes start with something as simple as what’s on your plate.
