Salmon has long been considered one of the healthiest foods you can put on your plate. But there is a growing difference between a wild salmon caught in its natural environment and seafood products created through increasingly sophisticated food technologies.

Before buying the newest “next-generation” seafood, consumers deserve to know exactly what they are eating, how it is produced, and how it compares with traditional wild-caught salmon.

WHAT IS “3D-PRINTED SALMON”?

The term sounds futuristic because the technology is. 3D food printing can be used to build foods layer by layer, creating specific shapes, textures, and structures.

In seafood, companies are exploring technologies that can combine proteins, fats, plant ingredients, and other components to reproduce the appearance and texture of a conventional salmon fillet.

There is also cultivated seafood, which is different from 3D-printed food. Cultivated seafood is produced from animal cells grown outside the animal and can then be developed into food products designed to resemble conventional seafood.

These technologies should not be confused with ordinary farmed salmon. But there is one obvious distinction: none of these products is the same thing as a wild salmon that lived and fed naturally in the ocean.

WHY WILD-CAUGHT SALMON IS DIFFERENT

Wild salmon develops in a natural ecosystem and gets its nutrients through its natural diet.

That matters because what an animal eats influences the nutritional composition of the animal itself.

Wild salmon is naturally rich in high-quality protein, EPA and DHA omega-3 fatty acids, vitamin B12, selenium, and other nutrients.

There is no need to engineer its texture, manufacture its appearance, or recreate its nutritional characteristics.

It already is salmon.

WHAT ABOUT FARMED SALMON?

Farmed salmon is real salmon, but it is raised very differently from wild salmon.

Farmed salmon is generally raised in controlled aquaculture environments and receives formulated feed rather than obtaining its entire diet from the natural marine food chain.

That difference can affect the nutritional composition of the fish. Farmed salmon can contain more total fat than many wild salmon varieties, while its fatty-acid profile depends in part on the ingredients used in its feed.

This does not mean every piece of farmed salmon is “toxic,” nor does it mean farmed salmon has no nutritional value. It means that wild and farmed salmon should not automatically be considered nutritionally identical.

THE FEED MATTERS

One of the biggest differences between wild and farmed salmon is what the fish eats.

Wild salmon participates in a natural food chain that can include zooplankton, krill, and smaller fish.

Farmed salmon receives manufactured feed designed to provide the nutrients needed for growth. Depending on the producer and formulation, that feed can contain fishmeal, fish oil, plant proteins, vegetable oils, grains, and other ingredients.

In other words, when you buy farmed salmon, you are buying an animal whose nutritional profile has been influenced by an industrial feeding system.

WHAT ABOUT CONTAMINANTS?

This subject requires some nuance.

Wild salmon is not automatically contaminant-free, and farmed salmon is not automatically dangerous. Both wild and farmed seafood can contain environmental contaminants depending on species, location, and production practices.

That is why the smartest approach is to pay attention to the species, origin, and source of your seafood rather than assuming that one label tells you everything.

For consumers who want a minimally processed traditional food, choosing wild-caught salmon from reputable sources is a straightforward option.

THE COLOR OF SALMON CAN FOOL YOU

One thing many shoppers don’t realize is that the bright orange-pink color of salmon does not automatically mean the fish was wild.

Wild salmon gets its characteristic color from carotenoids, including astaxanthin, obtained through its natural diet.

Farmed salmon can also receive astaxanthin through its feed, helping produce the familiar color consumers associate with salmon.

So don’t judge salmon simply by how bright orange it looks.

WHY WILD SALMON IS MY FIRST CHOICE

If I have the choice between a wild-caught salmon fillet and a highly engineered seafood alternative, the wild fish is the obvious choice for me.

Wild salmon is a whole animal food containing naturally occurring protein, fats, vitamins, minerals, and omega-3 fatty acids.

You don’t need a machine to recreate its texture.

You don’t need a laboratory to make it resemble salmon.

You don’t need to manufacture its nutritional identity.

Nature already did the work.

THE BOTTOM LINE

3D food printing and cultivated seafood may represent interesting technological developments, but “high-tech” does not automatically mean “healthier.”

Consumers should understand the difference between three very different products:

• Wild-caught salmon: Salmon harvested from its natural environment.
• Farmed salmon: Real salmon raised in an aquaculture system and fed formulated feed.
• 3D-printed or cultivated seafood: Newer technologies designed to reproduce the appearance, texture, or characteristics of conventional seafood.

If your priority is eating a traditional, minimally processed, nutrient-dense food, wild-caught salmon remains my first choice.

When shopping, look carefully at the package. Look for the words “wild-caught” and check the species and place of origin. Don’t assume that words like “premium,” “natural,” or “sustainable” automatically mean wild.

The closer your food is to what nature originally made, the easier it is to know what you’re actually eating.
