What is the Seagan Diet: Vegan Meets Seafood?

The Seagan Diet is a flexible dietary approach that combines the principles of vegan eating (no animal products, lots of plants, nuts, seeds, and legumes) with the selective inclusion of seafood, particularly fish and shellfish.

Think of it as:

• Mostly vegan (fruit, veggies, grains, legumes, nuts, and seeds)
• PLUS sustainable fish and/or shellfish

Unlike pescatarian diets (which may include dairy and eggs), Seagan eating deliberately avoids all other animal products while focusing on the power of plants + fish.

The term was popularized by Amy Cramer and Lisa McComsey in their book, Seagan Eating, in response to growing demand for a more practical, wellness-focused diet.

Why the Seagan Diet Matters for Your Health & Well-Being

• Optimal Omega-3 Intake: Fish—especially salmon, sardines, and mackerel—provide essential EPA and DHA fatty acids for heart, brain, and joint health. These are hard to get from plants alone.
• Complete Protein with Variety: Plants + seafood means you get all essential amino acids—a combo that supports muscles, energy, and satiety.
• Rich in Nutrients: Fish adds Vitamin B12, iodine, zinc, selenium, and vitamin D to a vegan base diet—nutrients vegans often lack.
• Low in Saturated Fat: Seagan diets typically feature low saturated fat, supporting cardiovascular and metabolic wellness.
• Gut Health & Fiber: Plant-based focus boosts gut microbiome and regularity.
• Flexibility & Sustainability: Easier to follow than fully vegan; more ethical and sustainable than omnivorous diets; supports ocean-friendly seafood choices.

Science-backed perks: Several large studies show regular fish eaters have lower rates of heart disease, cognitive decline, and depression. Meanwhile, plant-based diets reduce inflammation, cancer risk, and help with healthy weight management.

Common Challenges or Myths Around the Seagan Diet

• "Isn't this just pescatarianism?"
  Not quite—Seagan excludes all other animal products. The vegan foundation is crucial!
• "Seafood is risky because of mercury and toxins."
  Sustainable small fish and shellfish are low-risk and highly nutritious. We'll show you how to choose safe options.
• "It's too complicated or expensive."
  With proper planning, Seagan eating is budget-friendly and can be very simple—see our meal ideas below.
• "Can I get enough protein?"
  Absolutely! Combining beans, tofu, and fish easily covers all protein needs.
• "Isn't fish unsustainable?"
  Not all seafood is equal—responsible choices (like sardines, wild Alaskan salmon, or farmed mussels) are ocean-friendly.

Step-by-Step Solutions: How to Start the Seagan Diet

1. Start with Plants: Build your meals around whole grains (quinoa, brown rice), beans, lentils, veggies, seeds, and fruits.
2. Add Seafood 2-4 Times a Week: Choose low-mercury, sustainable fish (salmon, sardines, cod, trout, tilapia, mackerel, and shellfish like shrimp and mussels).
3. Exclude Other Animal Products: Avoid meat, poultry, dairy, eggs, and processed animal ingredients.
4. Use Plant-Based Fats and Flavors: Avocado, olive oil, nuts, tahini, miso, lemon, and seaweed boost taste and nutrition.
5. Supplement if Needed: Vitamin B12, vitamin D, and iodine may need topping up, depending on your seafood choices.
6. Meal Prep Simple Dishes:
   • Grain bowls with roasted veggies and grilled salmon
   • Chickpea salad with sardines and olive oil
   • Stir-fried tofu and broccoli with spicy shrimp
   • Vegan sushi with nori, avocado, cucumber, and smoked trout
7. Track Your Progress: Use a food journal or app to stay motivated and ensure nutrient coverage.

Tips from Experts & Scientific Studies

1. Follow the Seafood Watch Guide: The Monterey Bay Aquarium publishes an up-to-date list of sustainable choices (seafoodwatch.org).
2. SMART Planning: Registered dietitian Amy Cramer (author of "Seagan Eating") recommends “batch-cooking grains and beans, keeping canned or frozen fish on hand, and making your freezer your friend.”
3. Balance Omega-3s: Harvard researchers suggest aiming for two 3-4 oz servings of fatty fish weekly for maximum benefit without overdoing mercury.
4. Watch Labels: Nutritionist Lisa McComsey reminds, “Focus on whole foods, limit imitation seafoods and overly processed vegan snacks.”
5. Science Says: The British Medical Journal found people who consumed fish and plant-based diets had a 22% lower risk of heart disease compared to omnivores (source).
