3 min read

According to a 2018 Ipsos MORI report, approximately 3% of people worldwide identified as pescatarian, following a diet that includes fish and seafood in addition to vegetarian foods. This unique eating style is often chosen for its nutritional advantages, including heart-healthy omega-3s, and for ethical or environmental reasons.

Quick Summary

This guide defines the pescatarian diet, outlining its key characteristics and comparing it to vegetarianism. It explores the health, environmental, and ethical reasons for choosing this lifestyle, highlighting common food choices and nutritional considerations.

Key Points

  • Definition: A pescatarian is a person who eats a plant-based diet along with fish and seafood, but no other animal meat.

  • Health Benefits: The diet is rich in omega-3 fatty acids, supports heart and brain health, and is linked to a lower risk of chronic diseases.

  • Not Vegetarian: A pescatarian is not considered a true vegetarian because vegetarians exclude all animal flesh, including fish.

  • Food Variety: A pescatarian diet is highly flexible, including fruits, vegetables, grains, legumes, and nuts, in addition to seafood.

  • Ethical and Environmental: Many choose this diet for ethical reasons or to reduce their environmental impact compared to meat-heavy diets, though sustainable sourcing is important.

What is a Pescatarian Diet?

The term 'pescatarian' comes from the Italian word for fish, 'pesce,' and the English word 'vegetarian'. This diet is primarily plant-based but includes fish and seafood. Pescatarians eat fruits, vegetables, grains, nuts, and legumes, along with fish and shellfish, while excluding other animal meats like poultry and red meat. Many also include dairy and eggs, making it adaptable.

The Defining Line: Not a True Vegetarian

It's important to note that a pescatarian is not considered a vegetarian. True vegetarianism excludes all animal flesh, and fish are animals. While similar to a vegetarian diet, the inclusion of fish sets it apart. It can be seen as a form of semi-vegetarianism but has its own distinct identity.

Why Choose a Pescatarian Lifestyle?

People choose a pescatarian diet for various reasons, including health benefits, environmental concerns, and ethical considerations.

Health Advantages

  • Rich in Omega-3 Fatty Acids: Fatty fish provide beneficial omega-3s for heart and brain health and reduced inflammation.
  • Lower Risk of Chronic Diseases: This diet is linked to lower risks of heart disease, type 2 diabetes, and certain cancers compared to diets including red meat.
  • Weight Management: Protein from fish and plants can aid satiety and weight management.
  • Nutrient Boost: Fish offers nutrients like B12, iron, and zinc that can be harder to get from a strict vegetarian diet.

Environmental Considerations

Choosing fish over red meat and poultry can reduce environmental impact, particularly concerning greenhouse gas emissions. It's a way to lower one's carbon footprint without going fully vegan. Sustainable sourcing is key to avoid issues like overfishing.

Ethical Reasons

Some individuals feel more comfortable ethically consuming fish than land animals, sometimes based on beliefs about pain perception. Others see it as a step towards reducing overall animal product consumption.

Eggs/Dairy Eats both Eats both (optional) Eats both
Plant-based Foods Eats all types Eats all types Eats all types

A Guide to the Pescatarian Food List

A pescatarian diet includes plant-based foods plus seafood. Common foods include:

  • Seafood: Various fish and shellfish, from fatty fish like salmon to lean options like cod.
  • Legumes: Lentils, beans, chickpeas for protein and fiber.
  • Grains: Whole grains such as brown rice, quinoa, and oats.
  • Nuts and Seeds: Almonds, chia seeds for healthy fats.
  • Produce: All fruits and vegetables.
  • Dairy and Eggs: Often included, but optional.

Potential Considerations for the Pescatarian Diet

While beneficial, the pescatarian diet requires careful planning. Consuming certain fish too often can lead to high mercury exposure. The FDA advises limiting high-mercury fish and varying choices. Sustainable seafood choices, guided by resources like the Monterey Bay Aquarium's Seafood Watch, are important for health and the environment.

Conclusion

The pescatarian diet offers a nutritious and flexible way to reduce red meat and poultry consumption. Combining plant-based foods with fish provides a balanced approach to healthy eating, offering benefits from omega-3s and other nutrients. Though not vegetarian, it's a popular health-conscious choice that can be a step towards a more plant-focused lifestyle.
