Demystifying the Terminology: Beyond the Basic Vegetarian
Many people incorrectly assume that a vegetarian diet allows for the consumption of fish, leading to terms like "vegetarian that doesn't eat fish." In reality, true vegetarianism, by definition, excludes all animal flesh, which includes fish and other seafood. The person who eats a plant-based diet but includes fish is actually a pescetarian.
Why a Pescatarian is Not a Vegetarian
The fundamental difference lies in the consumption of animal flesh. A pescetarian, from the Italian word for fish "pesce," adds fish and seafood to a diet that is otherwise vegetarian. This dietary pattern offers certain nutritional benefits, such as omega-3 fatty acids, but because it includes animals, it is distinct from vegetarianism. This distinction is crucial for both dietary clarity and ethical considerations. Many people, for health or environmental reasons, choose a pescetarian diet as a stepping stone toward a more restrictive plant-based diet. Others may simply prefer it for its flexibility. The confusion arises because both diets prioritize plant foods, but the core principle of vegetarianism is the exclusion of all animal flesh.
The Nuances Within Vegetarianism
Not all vegetarian diets are the same. These variations primarily differ based on whether they include eggs, dairy, or both. The standard vegetarian diet people often refer to is actually a lacto-ovo-vegetarian diet.
Common types of vegetarianism include:
- Lacto-ovo-vegetarian: This is the most common form of vegetarianism. Followers consume dairy products (like milk, cheese, and yogurt) and eggs, but no meat, poultry, or fish.
- Lacto-vegetarian: This diet excludes eggs, meat, poultry, and fish, but permits dairy products.
- Ovo-vegetarian: Followers of this diet avoid meat, poultry, fish, and dairy products, but do eat eggs.
- Vegan: This is the most restrictive form, excluding all animal products and by-products, including eggs, dairy, and honey.
Nutritional Considerations for a Vegetarian Diet
When adopting a diet that excludes fish, which is a key source of omega-3 fatty acids and vitamin B12, it is important to plan meals carefully to ensure nutritional completeness. Fortunately, many plant-based and fortified foods can provide these essential nutrients. Below is a comparison of typical nutrient sources for different diets.
| Nutrient | Lacto-ovo Vegetarian Sources | Ovo-Vegetarian Sources | Vegan Sources | Pescatarian Sources |
|---|---|---|---|---|
| Protein | Eggs, dairy, legumes, nuts, seeds, tofu | Eggs, legumes, nuts, seeds, tofu, soy products | Legumes, nuts, seeds, tofu, tempeh, seitan | Fish, seafood, eggs, dairy, legumes, nuts, seeds |
| Omega-3 Fatty Acids | Flaxseeds, chia seeds, walnuts | Flaxseeds, chia seeds, walnuts | Algae-based supplements, flaxseeds, chia seeds | Fatty fish (salmon, mackerel, sardines), algae |
| Vitamin B12 | Dairy, eggs, fortified cereals | Fortified cereals, fortified plant-based milks | Fortified cereals, nutritional yeast, supplements | Fish, eggs, dairy, fortified foods |
| Calcium | Dairy products, fortified plant-based milk, leafy greens | Fortified plant-based milks, leafy greens, tofu | Fortified plant-based milks, leafy greens, tofu | Dairy products, leafy greens, fortified foods, canned fish with bones |
| Iron | Legumes, spinach, fortified cereals, eggs | Legumes, spinach, fortified cereals, tofu | Legumes, spinach, fortified cereals, tofu | Fish, legumes, leafy greens, fortified foods |
Common Misconceptions and Clarifications
The confusion surrounding "vegetarian that doesn't eat fish" is often perpetuated by inconsistent personal definitions and marketing. It's important to use the correct terminology to avoid miscommunication, especially in social or restaurant settings. A person who claims to be a vegetarian but eats fish is a pescetarian. The traditional vegetarian diet, which includes dairy and eggs but excludes all animal flesh, is precisely what a vegetarian that doesn't eat fish is.
Conclusion
To be clear, a vegetarian is someone who doesn't eat any animal flesh, which includes fish. Therefore, the phrase "vegetarian that doesn't eat fish" is a redundancy. A person on a plant-based diet who includes fish is correctly referred to as a pescetarian. For those adhering to a strictly plant-based diet, understanding the different types, such as lacto-ovo, lacto, and ovo-vegetarianism, is key to managing nutritional intake. A well-planned, balanced diet rich in plant-based sources can provide all the necessary nutrients, making dietary labels easier to navigate for both seasoned and new practitioners of plant-forward eating.

Frequently Asked Questions
Why do people get confused about the term "vegetarian" regarding fish?
The confusion often stems from differing personal definitions and the prevalence of pescetarianism. Because both vegetarians and pescetarians prioritize plant-based foods, people sometimes mistakenly group them together, despite the key difference of consuming animal flesh in the form of fish.
Can a pescetarian be called a vegetarian?
No, a pescetarian cannot be accurately called a vegetarian. The fundamental definition of a vegetarian is one who does not eat any animal flesh, and fish is animal flesh. A pescetarian is someone who follows a vegetarian diet but includes fish and seafood.
Is a lacto-ovo-vegetarian the same as a regular vegetarian?
Yes, the term "lacto-ovo-vegetarian" describes the most common type of vegetarian diet, which includes both dairy (lacto) and eggs (ovo) while excluding all meat, fish, and poultry. For many, this is the default understanding of a vegetarian.
What does a lacto-vegetarian not eat?
A lacto-vegetarian does not eat meat, poultry, fish, or eggs, but does consume dairy products.
What do you call a vegetarian who eats eggs but no dairy?
An individual who eats eggs but avoids meat, fish, and dairy is an ovo-vegetarian. The prefix "ovo" is Latin for egg.
Where do vegetarians get protein without fish?
Vegetarians can get ample protein from a variety of plant-based sources, including legumes, lentils, beans, nuts, seeds, tofu, and other soy products. Those who consume dairy and eggs also get protein from those sources.
What nutrients do you need to watch when you don't eat fish?
If you eliminate fish from your diet, it's important to pay attention to your intake of omega-3 fatty acids, vitamin B12, and vitamin D, as these are commonly found in fish. You can supplement these with fortified foods and plant-based sources like flaxseed, chia seeds, and algae supplements.
