Including fish in your diet can be beneficial, but there is concern that certain species may be harmful to your brain. In this post, we'll take a closer look at five species of fish that have been linked to the presence of contaminants or poisons that can cause neurological problems.
Healthline states that the Gulf of Mexico and the Atlantic Ocean are both home to the species known as tilefish, which is also known as golden snapper or goldband snapper. Popular due to its mild flavor and flaky white meat. The problem is that tilefish can have dangerously high concentrations of mercury, a poisonous metal that can build up in the body over time.
Mercury poisoning can cause a variety of mental and behavioral issues due to its effects on the central nervous system. Mercury poisoning can lead to tremors, memory loss, and coordination and balance issues in the most extreme cases. Tilefish is high in mercury, thus pregnant people, nursing mothers, and small children should stay away from it.
According to healthline There have been reports of excessive mercury levels in swordfish. Like tilefish, it is considered a delicacy and may be found in the Atlantic and Gulf of Mexico. However, due to its mercury concentration, the FDA discourages the consumption of swordfish, especially by pregnant women and young children.
Polychlorinated biphenyls (PCBs) and dioxins are two more pollutants that have been found in swordfish. Children exposed to these chemicals are more likely to suffer from cognitive impairments such delayed development and learning difficulties.
Shark, like many other fish, may have dangerously high concentrations of mercury and other pollutants including PCBs and dioxins. The Food and Drug Administration warns against eating shark for similar reasons as swordfish.
Trimethylamine oxide (TMAO) is a neurotoxin found in shark meat; eating it has been associated with an increased risk of stroke and heart disease. Certain bacteria degrade the shark protein amino acid trimethylamine, which is present in high concentrations, to create TMAO.
Atlantic and Gulf of Mexico waters are frequent habitats for king mackerel, sometimes known as kingfish or king croaker. As a result of its solid, tasty meat, it is frequently utilized in sushi and sashimi. Yet, king mackerel may be hazardous to your brain and nervous system due to its high mercury content.
King mackerel may also be contaminated with PCBs and dioxins in addition to mercury. Cancer and immune system issues are only two of the many illnesses that have been associated to these chemicals. Consumption of king mackerel should be avoided by pregnant women and young children due to their susceptibility to the negative effects of these pollutants.
Tuna is a popular fish eaten all over the world, however there are some varieties that may be damaging to your brain and neurological system due to their high mercury content. In particular, the FDA cautions against pregnant women and small children eating too much tuna.
Bigeye, ahi, and yellowfin tuna are all species of fish that tend to have higher mercury concentrations. Because of their larger size and longer lifespan, this species of tuna may accumulate more mercury in their flesh. Although canned light tuna tends to have lower mercury content than other varieties of tuna, it is still wise to limit your intake.
