Many people know about the exceptional benefits of eating fish, but choosing the best fish to eat can be a challenge. Some fish varieties are high in certain nutrients, but may also contain high levels of mercury. Other popular varieties may be delicious and safe, but lacking in those essential nutrients and healthy fats that people look for in fish. Fortunately, with fish representing about 20% of protein intake for more than 2.5 billion people in the world, there is plenty of research about the best fish to eat.

Fishes You Should Avoid
While there are many fishes that are nutrient-dense and extremely healthy, there are many varieties that are low in nutrients and potentially high in toxins. Mercury contamination is a major problem with many types of commercially harvested fishes, even those that are popular in restaurants around the world. Other fishes are bottom feeders, making it difficult to know precisely what other environmental or artificial pollutants are present in the fish. It is always best to choose farm-raised fishes, or those that are locally sourced from reliable producers. Some of the fish varieties with the worst reputation for toxicity or overfishing include the following:
- Orange Roughy
- Farmed Eel
- Imported Catfish
