✅ Canned counts! Sardines, salmon, and mackerel in water or olive oil retain omega-3s.
🌱 For Plant-Based Diets
Flaxseeds, chia seeds, walnuts, and algae oil provide ALA omega-3s, but the body converts ALA to EPA/DHA inefficiently (<10%). Algae-based supplements are the best vegan source of direct DHA/EPA.
⚠️ A Note on Mercury
- Avoid high-mercury fish: shark, swordfish, king mackerel, tilefish.
- Safe for most: salmon, sardines, trout, herring—even during pregnancy (in moderation).
❤️ How to Enjoy It
- Bake: Salmon with lemon & dill (12–15 mins at 400°F)
- Pan-sear: Sardines on toast with avocado
- Add to salads: Canned mackerel or salmon
- Grill: Trout stuffed with herbs
The Bottom Line
Experts don’t just like fatty fish—they prescribe it as preventive medicine. As Dr. Frank Sacks (Harvard School of Public Health) puts it:
“No supplement matches the benefits of eating whole fish.”
So aim for two 3–4 oz servings per week. Your heart, brain, and future self will thank you. 🐟💙
