It's important to clarify that true vegans do not eat fish. The term for someone who eats fish but not other meat is often referred to as a pescatarian. The question implies a misunderstanding of veganism, which excludes all animal products, including fish. However, some individuals who may identify as "vegan" in casual conversation might consume fish, and here's why:
Misunderstanding of Terminology
- Pescatarianism vs. Veganism: Many people might use the term "vegan" loosely to describe a plant-based diet while still including fish, which technically classifies them as pescatarian. This is a key distinction.
- Dietary Choices: People may choose a diet that is predominantly plant-based, but they include fish for specific reasons. This isn't actually vegan, but the individual may be confused on terminology.
Reasons for Including Fish in a Plant-Based Diet
Although technically not vegan, here are some reasons a person might choose to consume fish while eating a diet that is otherwise plant-based:
-
Health Benefits:
- Nutrient Rich: Fish and seafood are great sources of protein and contain important vitamins and minerals (like zinc and vitamin B12), that can be hard to obtain from a strict plant-based diet ( 2, 3, 4 ). This is mentioned in the provided reference.
- Immune & Nervous System Support: These nutrients are essential for healthy immune and nervous system function. The reference states that this is why fish is important.
- Omega-3 Fatty Acids: Fish is also a fantastic source of omega-3 fatty acids, which are important for cardiovascular health and brain function. These are very hard to find in significant quantities in plant-based foods.
-
Transition Phase: Some people may be transitioning from an omnivorous diet to a fully vegan one, and fish may be one of the last animal products they give up.
Key Differences
Here's a quick summary of key differences:
| Term | Definition | Includes Fish? | Includes Other Animal Products? |
|---|---|---|---|
| Vegan | Excludes all animal products, including meat, fish, dairy, eggs, and honey. | No | No |
| Pescatarian | A vegetarian diet that includes fish and seafood. | Yes | No |
| Vegetarian | Diet that does not include meat, but may include eggs and dairy. | No | Yes |
Conclusion
It is important to understand that a true vegan diet does not include fish. When someone seems to be eating fish while identifying as "vegan," it's either due to a misunderstanding of the term or an intentional dietary choice that doesn't fully align with vegan principles. It's often more accurate to describe that person as pescatarian.
