6- Farmed salmon
Your body needs the healthy Omega-3 fats in most fish, but farmed salmon is fed an unnatural diet full of pesticides, chemicals, antibiotics, and other known carcinogens. As a result, their meat is full of cancer-causing PCBs, mercury, and dioxins. Unfortunately, nearly 60% of salmon in the stores today is farmed.
To be safe, look for labels that specifically indicate wild-caught sockeye salmon.
