If you’ve ever searched pescetarian vs pescatarian, you’ve probably wondered whether these are two different diets—or simply two spellings of the same word. The good news is that the answer is much simpler than it first appears.
Pescetarian and pescatarian generally refer to the same eating pattern: a person who avoids meat but eats fish and other seafood. Major dictionaries recognize pescatarian, while Cambridge also lists pescetarian as an alternative form.
So, is one spelling actually correct? Let’s break down the difference, where the words come from, what the diet includes, and how to use each term naturally.
Pescetarian vs Pescatarian: What’s the Difference?
In practical terms, there is no meaningful difference in the diet described by “pescetarian” and “pescatarian.”
Both terms are used for someone who does not eat meat but does eat fish. Cambridge explicitly lists pescetarian as another form of pescatarian, while Oxford defines pescatarian as a person who does not eat meat but does eat fish.
Here’s the simple comparison:
| Term | Meaning | Common status |
| Pescatarian | Eats fish but not meat | Established dictionary form |
| Pescetarian | Eats fish but not meat | Recognized alternative spelling |
| Pescatarian diet | A diet excluding meat while allowing fish/seafood | Common usage |
| Pescetarian diet | Same basic eating pattern | Alternative usage |
In other words, pescatarian vs pescetarian is primarily a spelling and word-form question, not a difference between two diets.
What Is a Pescatarian?
A pescatarian is someone who avoids meat but eats fish. Oxford gives essentially this definition, and Cambridge similarly describes a pescatarian as someone who eats fish but not meat.
Depending on the individual, a pescatarian diet may include:
- Fish
- Shellfish
- Eggs
- Milk and dairy products
- Vegetables
- Fruits
- Beans and lentils
- Whole grains
- Nuts and seeds
- Other plant-based foods
There isn’t necessarily one universal pescatarian menu. People can follow the eating pattern in slightly different ways depending on their preferences, culture, nutrition goals, and personal reasons for avoiding meat.
What Is a Pescetarian?
Pescetarian means essentially the same thing.
Cambridge lists pescetarian as an alternative form of pescatarian and uses the term to describe someone who eats fish but does not eat meat.
So if someone says:
“I’m pescetarian.”
and another person says:
“I’m pescatarian.”
They are generally describing the same type of diet.
The spelling may look different, but the underlying meaning is the same.
Pescatarian vs Pescetarian: Which Spelling Is Correct?
If you’re wondering pescatarian or pescetarian, both forms are recognized, but pescatarian is the more straightforward choice for standard English writing because it is the headword used by major dictionaries such as Oxford and Cambridge.
That doesn’t make pescetarian wrong. Cambridge specifically identifies it as an alternative form.
For an article, school assignment, professional document, or general-purpose writing, pescatarian is a safe choice.
Why Are There Two Spellings?
The word is relatively modern. Oxford dates its origin to the 1990s and explains that it comes from the Italian word pesce, meaning “fish,” combined with the pattern of vegetarian.
Because the word was formed relatively recently, variations in spelling developed naturally.
The two forms are close enough in pronunciation and structure that both have remained in use.
Pescetarian vs Pescatarian Pronunciation
The spelling difference can make pronunciation seem confusing.
Cambridge gives pronunciations for pescatarian in both British and American English. In everyday speech, the word is commonly pronounced roughly like:
pes-kuh-TAIR-ee-un
or, depending on accent:
pes-kuh-TEER-ee-un.
The exact pronunciation can vary by region, so don’t be surprised if you hear slightly different versions.
The important point is that pescetarian and pescatarian are not normally pronounced as completely different diet names.
What Do Pescatarians Eat?
A pescatarian diet can be surprisingly flexible.
Someone following this eating pattern might have oatmeal and fruit for breakfast, a vegetable-and-grain bowl for lunch, and grilled salmon with vegetables for dinner.
Typical foods can include:
Protein sources
- Salmon
- Tuna
- Sardines
- Cod
- Trout
- Shrimp
- Mussels
- Eggs
- Beans
- Lentils
- Tofu
- Nuts and seeds
Plant foods
- Leafy greens
- Tomatoes
- Peppers
- Broccoli
- Potatoes
- Whole grains
- Fruits
- Legumes
- Seeds
Dairy, if included
Many pescatarians also eat:
- Milk
- Yogurt
- Cheese
- Butter
However, individual eating habits vary. Someone may combine pescatarian eating with other restrictions, such as avoiding dairy or eggs.
Does a Pescatarian Eat Chicken or Beef?
Generally, no.
The defining feature of a pescatarian diet is that it excludes meat while allowing fish. That means traditional pescatarian eating does not include:
- Beef
- Pork
- Lamb
- Chicken
- Turkey
Fish and seafood are the notable animal-based foods that distinguish this eating pattern from a traditional vegetarian diet.
Of course, people sometimes use dietary labels differently in casual conversation, so it’s always worth asking about someone’s specific food preferences if you’re cooking for them.
Is a Pescatarian a Vegetarian?
This is where things can get a little complicated.
In strict dietary terminology, pescatarians and vegetarians are generally treated as different groups because vegetarian diets traditionally exclude meat and fish. Cambridge defines vegetarianism around not eating meat, while pescatarian diets specifically allow fish.
So, although pescatarian eating is often described as vegetarian-adjacent or largely plant-based, calling a pescatarian simply “vegetarian” can be misleading.
A better description is:
A pescatarian avoids meat but eats fish and seafood.
That makes the distinction clear without getting caught up in labels.
Pescatarian vs Vegetarian vs Vegan
Understanding the neighboring diets makes the pescatarian vs pescetarian question even easier.
| Diet | Meat | Fish/Seafood | Eggs | Dairy |
| Pescatarian | No | Yes | Usually | Usually |
| Vegetarian | No | No | Often | Often |
| Vegan | No | No | No | No |
There are additional variations within each category, but this table gives you the basic distinction.
For example, an ovo-lacto vegetarian may eat eggs and dairy while avoiding both meat and fish. Cambridge specifically defines an ovo-lacto vegetarian as someone who does not eat meat or fish but does eat eggs and milk or foods made from milk.
Why Do People Follow a Pescatarian Diet?
People choose pescatarian eating patterns for many different reasons.
Some want to reduce their consumption of red meat or other meats without giving up animal-based foods completely. Others enjoy seafood and find a fish-inclusive diet easier to maintain than strict vegetarian or vegan eating.
Common motivations can include:
- Personal food preferences
- Environmental concerns
- Ethical considerations
- Cultural or religious practices
- Interest in eating more plant foods
- A desire to reduce meat consumption
- Enjoyment of fish and seafood
There is no single reason that defines a pescatarian.
Is a Pescatarian Diet Healthy?
A well-planned pescatarian diet can provide a wide variety of nutrient-rich foods, particularly when it emphasizes vegetables, fruits, legumes, whole grains, nuts, seeds, and appropriate seafood choices.
However, the label itself does not automatically make a diet healthy.
A pescatarian could eat mostly vegetables, beans, whole grains, and fish—or could consume large amounts of refined carbohydrates, fried seafood, sugary foods, and highly processed products.
As with any eating pattern, overall food quality matters.
People following a pescatarian diet should pay attention to getting adequate nutrients such as:
- Protein
- Iron
- Vitamin B12
- Calcium
- Vitamin D
- Omega-3 fatty acids
- Zinc
The exact nutritional needs vary from person to person.
What Is the Origin of the Word Pescatarian?
The word pescatarian is relatively modern.
Oxford explains that the term dates from the 1990s and comes from Italian pesce, meaning “fish,” combined with the word pattern of vegetarian.
That origin helps explain why the spelling can feel slightly unusual. It combines a word associated with fish with the familiar structure of vegetarian.
The alternative pescetarian spelling has also become established enough to appear in dictionary usage. Cambridge lists it as an alternative to pescatarian.
How to Remember Pescatarian vs Pescetarian
If you frequently mix up the two spellings, try connecting the word with its meaning.
Pescatarian contains the sequence “pescata”, while pescetarian uses “pescete.”
A simple way to remember the preferred spelling is:
Pescatarian = fish + vegetarian-style eating.
And if you encounter pescetarian, don’t assume it refers to a different diet. It is a recognized alternative form.

Mistake 5: Thinking “Pescetarian” Is Simply a Typo
It isn’t necessarily a typo. Cambridge recognizes pescetarian as an alternative form.
