Polluted Seas, Compromised Health: Rethink Fish Consumption
The oceans are increasingly contaminated, making seafood a significant source of human exposure to harmful pollutants, including DDT, PCBs, dioxins, heavy metals, and forever chemicals. Although fish, particularly salmon and canned tuna, is often promoted for its omega-3 fatty acids, the presence of these pollutants counteracts potential health benefits and may contribute to various metabolic issues such as insulin resistance, glucose intolerance, and chronic low-grade inflammation. Additionally, mercury contamination poses a serious risk to brain health, with maternal consumption of contaminated fish linked to brain damage in newborns and cases of memory loss in adults erroneously diagnosed with dementia. Removing contaminated fish from their diets has led to notable health improvements, suggesting that healthcare professionals should consider screening for mercury toxicity in patients experiencing hair loss or cognitive decline. Overall, the current state of fish consumption warrants a thorough reevaluation due to the detrimental effects of chemical pollutants, overshadowing its perceived nutritional benefits.
