10 Fish You Should Steer Clear of Ordering at a Restaurant

Ordering seafood at a restaurant often feels like a healthy choice, but not every fish on the menu is good for your heart health, your environmental footprint, or your long‑term wellness. Some species carry high mercury levels, others come from unsustainable sources that harm marine ecosystems, and a few are raised in conditions that compromise both food safety and nutritional value.

Here’s an in‑depth guide to the fish you should skip—and the sustainable seafood options that support a healthier planet and a healthy lifestyle.

1️⃣ Tilapia – The Bottom Feeder With Low Nutritional Value

Tilapia is affordable and mild, but it’s known as a bottom feeder, which often means exposure to pollutants in poorly managed farms. Its low omega‑3 content also offers little benefit for heart health compared to other fish.
💡 Why skip it: Minimal omega‑3 fatty acids, questionable farming conditions, potential food safety concerns.
✅ Better choice: Try wild‑caught rainbow trout or U.S. farmed catfish, which are rich in nutrients and raised under stricter regulations.

2️⃣ Atlantic Cod – A Species Hit by Overfishing

Atlantic cod has been a classic on many menus, but decades of unsustainable fishing have devastated populations, creating serious environmental impact concerns.
💡 Why skip it: Contributes to overfishing, reduced biodiversity.
✅ Better choice: Choose Pacific cod or Alaskan pollock—both are widely recognized as sustainable seafood choices with excellent flavor and nutritional value.

3️⃣ Farmed Atlantic Salmon – Artificial Color and Hidden Issues

Farmed Atlantic salmon often looks appealing, but many farms use dyes to create that pink hue. It can also have higher saturated fats and contain residues of antibiotics.
💡 Why skip it: Lower nutritional quality, potential contaminants, poor farming practices.
✅ Better choice: Opt for wild Alaskan salmon or sockeye salmon, packed with omega‑3s that promote heart health, brain function, and a strong immune system.

4️⃣ Bluefin Tuna – An Endangered Luxury

Bluefin tuna is often sold as a premium item, but its population is critically low. Ordering it increases demand on an already threatened species.
💡 Why skip it: Endangered species, high mercury levels.
✅ Better choice: Try albacore tuna or skipjack tuna, which are safer for regular consumption and lower in mercury, making them better for a balanced diet.
