How to Eat Fish Safely

- Q: I keep hearing about toxins in fish. Is it safe to eat?
- A: Yes, experts say that most seafood is healthy to eat twice a week. But it’s important to avoid the less-healthy types that may be contaminated with pollutants.
Seafood has a long list of health benefits, including high-quality protein, low levels
of saturated fat, and heart-healthy omega-3s. Some types, though, also contain PCBs or mercury, which could harm developing babies. Happily, it’s actually pretty easy to make a healthy choice and avoid the risks. Here’s how.
“The best way to reduce exposure to contaminants is to eat fewer big fish,” says Tim Fitzgerald, MS, a scientist and senior policy specialist with the Environmental Defense Fund. Pollutants from the atmosphere regularly settle into the ocean, and fish that grow very big—predators like shark, marlin, and Chilean sea bass—accumulate more contaminants in their bodies during their long lives.
Mix it up
Put seafood on the menu at least twice a week and mix up the varieties you eat to lower the risks of contaminants. If you like tuna, for instance, eat it only once a week because it’s a bigger fish; choose something smaller—say, shrimp—for your next meal. Whatever you do, don’t stop eating all seafood out of fear. “Eating fish is the single best dietary change you can make to reduce your heart disease risk,” says Dariush Mozaffarian, MD, co-director of the Harvard School of Public Health’s Program in Cardiac Epidemiology. Studies suggest that the abundant omega-3 fats in seafood help your heart by lowering blood-fat levels, slowing the buildup of plaque in your arteries, and slightly lowering blood pressure.
The safest catches
These varieties of seafood are low in contaminants, great sources of omega-3s, and easy on the planet (they’re not caught by trawls and dredges, which damage the ocean floor), according to the new “Super Green” list from Harvard School of Public Health, Monterey Bay Aquarium’s Sea-food Watch, and the Environmental Defense Fund.

- Salmon (wild, from Alaska)
- Oysters (farmed)
- Pink shrimp (wild, from the Pacific Northwest)
- Rainbow trout (farmed)
- Albacore tuna (pole-caught, from the United States or Canada)
