Maybe you’re at a dinner party. Someone passes the smoked salmon, and you wave it away. Then comes the inevitable question: "Oh, are you a vegetarian?" You hesitate. You eat chicken, but the thought of a sardine makes you shudder. Or perhaps you’re the opposite—you love a good ribeye but think tuna is "too fishy." People want a label. They always do. But what is it called when you don't eat fish, specifically?
The answer isn't just one word. It depends entirely on what else is on your plate. If you cut out fish but keep the steak, you aren't a vegetarian. You're just a person who doesn't like seafood. Honestly, there isn't a fancy, Latin-rooted medical term for "everything but the sea creatures." However, the nuances of these dietary choices matter more than most people realize.
The Pescatarian Inverse and Why Names Matter
We all know what a pescatarian is. It’s that person who skips the burgers but goes all-in on the sushi. So, what do we call the reverse? If you eat meat but avoid seafood, you are essentially following a standard diet with a specific exclusion. In the world of clinical nutrition and allergy management, this is often simply referred to as a seafood-free diet.
It sounds boring. It lacks the "flair" of words like vegan or paleo. But labels serve a purpose beyond social signaling. For some, it's about a life-threatening allergy. For others, it’s a sensory thing—texture, smell, or that weird "metallic" aftertaste some white fish has.
Vegetarians vs. Vegans vs. The Rest of Us
If you don't eat fish because you don't eat any animals, you're a vegetarian. If you don't eat fish, meat, dairy, or honey, you're a vegan. This is straightforward. But the confusion usually happens in the "gray area" of the flexitarian movement.
A flexitarian might eat fish once a month but avoid it the rest of the time. There is also the pollotarian. These folks eat poultry like chicken and turkey but stay away from red meat and fish. If you are a pollotarian, you’ve basically answered the question of what it's called when you don't eat fish by replacing it with a bird-based alternative.

Why People Ditch the Fin
Why would someone stop eating fish? It’s not always about the "ick" factor.
- Mercury and Toxins: This is a big one. Big fish like swordfish and king mackerel are notorious for high mercury levels. According to the EPA and FDA, pregnant women and young children have to be incredibly careful. Some people just decide the risk isn't worth it.
- Sustainability and Overfishing: Take a look at the documentary Seaspiracy. Whether you agree with all its claims or not, it opened a massive conversation about commercial fishing's impact on our oceans. Microplastics are another huge concern.
- The Texture Issue: Let’s be real. If fish isn't cooked perfectly, it's slimy. Or rubbery. Or it falls apart in a way that feels "off" to people used to the chew of a steak.
- Allergies: Shellfish and finfish allergies are among the most common adult-onset food allergies. They don't mess around. Anaphylaxis is a very real threat.
It’s actually quite common to see people who grew up in landlocked areas avoid fish because they never had it fresh. If your only experience with fish is a soggy stick from a high school cafeteria, you'd probably want a label to avoid it too.
The Nutrient Gap: What Happens When Fish Leaves the Menu?
Fish is often touted as a "superfood." When you stop eating it, your doctor might start hovering over your blood test results, specifically looking at your Omega-3 levels. Fish, especially fatty ones like salmon and sardines, are packed with EPA and DHA.
What is it called when you don't eat fish but still want to stay healthy? It’s called being smart about your plant-based fats. You can't just quit fish and expect your brain to be happy without a replacement. You have to look at things like flaxseeds, chia seeds, and walnuts. But there's a catch—the ALA found in plants has a terrible conversion rate to DHA in the human body.
Many people who avoid fish end up taking algae-based supplements. Fun fact: Fish don't actually produce Omega-3s themselves. They get them from eating algae. By taking an algae supplement, you're just cutting out the middleman (or the middle-fish).

Social Pressures and the "Pickys"
Is there a social stigma? Sorta. In coastal cultures, refusing fish can feel like a personal insult to the chef. If you're in Portugal or Japan and you say you don't eat fish, people look at you like you have two heads.
There isn't a specific "movement" for non-fish eaters. There’s no "Anti-Fish Association." Because of this, people who don't eat fish often feel like they have to justify their choice more than a vegan does. A vegan has a philosophical framework. A "meat-eater-who-hates-fish" just sounds like a picky kid to some people.
But it’s not just about being picky. Many people have a genuine physiological "disgust response" to the smell of trimethylamine—that "fishy" odor that occurs as fish starts to decompose. Some people are genetically more sensitive to this scent than others. It's not a choice; it's biology.
Practical Steps for a Fish-Free Life
If you’ve decided to cut fish out of your life, or if you’ve never liked it and want to make sure you’re doing things right, you need a plan. You don't need a fancy name for your diet, but you do need a balanced plate.
Diversify Your Protein
Don't just lean on chicken. If fish is out, explore lentils, chickpeas, and fermented soy like tempeh. These provide the protein density you might be missing, plus a lot of fiber that fish lacks.

Monitor Your Iodine
This is a big one people forget. Fish and seaweed are major sources of iodine in the Western diet. If you cut them out, make sure you're using iodized salt. If you’re a "fancy salt" person who only uses Himalayan pink salt, you might actually become iodine deficient. That leads to thyroid issues. Not fun.
The Omega-3 Strategy
Don't rely on luck. If you're serious about your health and you're skipping the salmon, buy a high-quality algae oil supplement. Look for one that specifically lists DHA and EPA on the back. Most "plant-only" Omega-3 supplements only have ALA, which isn't enough for optimal brain health.
Communication is Everything
When you're at a restaurant, don't just say you're a vegetarian if you're not. It confuses the kitchen. Just say, "I have a strict seafood exclusion." It sounds professional, and it gets the point across. If it's an allergy, say it's an allergy. If it's a preference, just say you don't eat anything from the water.
The Reality of the "No-Fish" Label
At the end of the day, what is it called when you don't eat fish? It’s called a personal dietary choice. Whether you call yourself a pollotarian, a vegetarian, or just "someone who hates trout," the label is less important than the nutrition.
The food landscape is changing. More and more people are moving away from traditional seafood due to environmental concerns or simple taste preferences. You don't need a "-arian" suffix to justify what you put on your fork. Just eat what makes you feel good, keep an eye on your Omega-3s, and make sure you're getting enough iodine from other sources.
The next time someone asks you what your diet is called, you can tell them it doesn't have a specific name—it's just a way of eating that works for you. And honestly, that's enough.
Stop worrying about the terminology and start focusing on the quality of the food you actually enjoy. If that means a plate of beans or a roasted chicken instead of a sea bass, go for it. Your health is about the total picture, not a single missing ingredient.
- Audit your pantry: Switch to iodized salt if you’ve been using non-iodized versions and don't eat seaweed.
- Check your supplements: Look for "Algal Oil" to replace the Omega-3s typically found in fish.
- Vary your proteins: Incorporate more legumes and poultry to ensure you aren't just eating processed carbs in place of seafood.
- Be clear with hosts: Use the phrase "dietary exclusion" to clearly communicate your needs without needing a confusing label.
