12. Farmed Salmon
Farmed salmon might seem like a healthy choice, but it often contains higher levels of contaminants like polychlorinated biphenyls (PCBs) compared to wild salmon. PCBs are industrial compounds that can increase cancer risk. Opt for wild-caught salmon to enjoy the health benefits of this fish without the added risks.
Evidence from Studies
Studies have found that farmed salmon can contain significantly higher levels of PCBs and other contaminants compared to wild salmon. A study published in the journal Science found that farmed salmon had higher concentrations of these chemicals, which are potential carcinogens.
Reducing the Risk
- Choose Wild-Caught Fish: Opt for wild-caught fish whenever possible.
- Diverse Seafood: Include a variety of seafood in your diet to minimize exposure to contaminants.
- Organic Options: Look for organic or sustainably farmed fish with lower contaminant levels.
