What Seafood Can You Eat on a Seagan Diet?

5 min read

The seagan diet combines plant-based eating with sustainable seafood, providing essential nutrients often lacking in a strict vegan regimen, such as omega-3 fatty acids. This increasingly popular diet offers a flexible approach to incorporating healthy fats while maintaining a vegan foundation.

Quick Summary

The seagan diet incorporates specific, sustainably sourced seafood options to a vegan lifestyle. Focus on low-mercury, omega-3-rich fish and responsibly harvested shellfish while avoiding certain species to maximize health benefits and minimize environmental impact.

Key Points

  • Sustainable Choices are Key: On a seagan diet, it is essential to prioritize sustainably sourced seafood to protect ocean health and biodiversity.

  • Emphasize Low-Mercury Fish: To minimize heavy metal exposure, focus on smaller fish lower on the food chain, such as sardines, mackerel, and wild salmon.

  • Include Oily Fish for Omega-3s: Oily fish like salmon, sardines, and herring are excellent sources of beneficial omega-3 fatty acids (EPA and DHA), which are less efficiently absorbed from plant sources.

  • Don't Forget Shellfish: Many shellfish, including oysters, mussels, clams, and scallops, are considered sustainable options with a low environmental impact.

  • Vary Your Seafood: Eating a variety of sustainable seafood, including oily and white fish, ensures a broader intake of essential nutrients like protein, vitamins, and minerals.

  • Use Certification Guides: To help make eco-friendly seafood choices, consult guides from organizations like the Marine Stewardship Council (MSC) and Seafood Watch.

  • Balance with a Plant-Based Base: Seafood should complement, not replace, a primarily plant-based diet rich in fruits, vegetables, legumes, nuts, and seeds.

Understanding the Seagan Diet

The seagan diet, a term popularized in 2016, blends a primarily plant-based vegan lifestyle with the selective addition of sustainable seafood. Unlike a pescetarian diet, seaganism excludes all other animal products, including eggs and dairy. The core philosophy is to leverage the benefits of a plant-heavy diet while supplementing with seafood to acquire key nutrients like vitamin B12, vitamin D, and omega-3 fatty acids, which can be harder to obtain solely from plant sources. A critical component of seaganism is prioritizing sustainability and avoiding species with high mercury levels or those from unsustainable fishing practices. This makes consulting resources like the Monterey Bay Aquarium's Seafood Watch a frequent practice for dedicated seagans.

Low-Mercury and High Omega-3 Seafood Choices

For seagans, the best seafood options are those low in mercury and high in beneficial omega-3s (EPA and DHA). Choosing smaller fish that are lower on the food chain is a good general rule of thumb for minimizing mercury intake. These are often the same species that are rich in healthy oils. Regular consumption of oily fish, such as mackerel or sardines, two to three times a week is often recommended for maximum benefit.

Omega-3-Rich Fish

  • Wild Alaska Salmon: A premium, omega-3-rich fish considered a top choice for its health benefits and responsible harvesting. It is widely available fresh, frozen, and canned.
  • Sardines: A powerful source of omega-3s, sardines are small, low-mercury fish that can be enjoyed canned or fresh. They also offer an excellent source of calcium when the bones are consumed.
  • Atlantic Mackerel: Another excellent choice for its omega-3 content. Atlantic mackerel is typically lower in mercury than its king mackerel counterpart.
  • Herring: Similar to sardines and mackerel, herring is a small, oily fish known for its high concentration of omega-3 fatty acids and low mercury levels.

Other Low-Mercury Fish

  • Rainbow Trout (farmed): A good option for those seeking a lighter flavor. Farmed rainbow trout is a low-mercury choice that can be sustainably sourced.
  • Arctic Char: Praised for its buttery flavor, this fish is an environmentally friendly choice with low mercury levels.
  • Pacific Cod: While not as high in omega-3s as oily fish, Pacific cod provides a lean protein source and is considered a good choice for sustainability and low mercury content.

Sustainable Shellfish for Seagans

Shellfish are another important component of the seagan diet, offering various nutrients, including zinc, iron, and protein. Many types of shellfish are low in mercury and have minimal environmental impact, especially when responsibly farmed or harvested.

Environmentally Friendly Shellfish

  • Oysters: Both wild-caught and farmed oysters are generally sustainable and a good source of zinc. They are filter feeders and can even improve water quality.
  • Mussels and Clams: These bivalve mollusks are considered one of the most sustainable seafood choices, particularly when farmed. They have a low environmental footprint and are high in omega-3s, B12, and iron.
  • Scallops: Farmed and wild scallops are generally well-managed and provide a tasty source of protein and B12.
  • Shrimp: While sourcing can be complex, sustainably farmed domestic shrimp or wild-caught varieties from well-managed fisheries can be included. Looking for certifications like those from the Aquaculture Stewardship Council (ASC) is key.

A Guide to Buying Sustainable Seafood

Choosing the right seafood requires knowledge. Several organizations offer guides to help consumers make informed decisions that benefit both health and the environment. Websites like Seafood Watch provide recommendations based on species, catch location, and harvest method. Products from fisheries certified by the Marine Stewardship Council (MSC) or farms certified by the ASC are excellent starting points.

Sustainable vs. Unsustainable Seafood Comparison

Aspect Sustainable Choice Unsustainable Choice
Species Example Wild Alaska Salmon Bluefin Tuna
Sourcing MSC-certified, Wild-Caught, Well-Managed Fishery Critically Overfished Stocks
Mercury Levels Low (e.g., Sardines, Mussels) High (e.g., Swordfish, King Mackerel)
Impact Minimal effect on habitat and bycatch Destructive harvesting methods
Labeling Look for MSC or ASC certification logos No certification or unclear origin

Incorporating Seafood into Your Seagan Diet

Transitioning to or maintaining a seagan diet involves balancing a diverse, nutrient-dense plant base with select seafood. Aiming for two to three servings of sustainable seafood per week can fill nutritional gaps effectively. This could look like grilled salmon on a large vegan salad, sardines on avocado toast for a nutritious snack, or a plant-based curry featuring mussels or shrimp. Prioritizing variety, such as combining oily fish with white fish and shellfish, ensures a wide range of vitamins and minerals are obtained. Sourcing high-quality, sustainable seafood from reputable fishmongers or checking for certification on packaged products is essential for adhering to the seagan philosophy.

Conclusion

The seagan diet provides a practical and sustainable pathway for those who wish to combine the health benefits of plant-based eating with the nutritional advantages of seafood. By making informed choices focused on sustainable, low-mercury species like wild Alaska salmon, sardines, mackerel, and various shellfish, you can support your health and the environment. Responsible sourcing from certified fisheries is crucial to this approach. A mindful seagan diet is a delicious and healthy compromise that is kind to both your body and the planet.
