Fish can be an important part of a healthy diet,
containing essential nutrients such as omega-3 fatty acids. That can reduce the
likelihood of you developing cardiovascular disease, cancer, Alzheimer's, etc.
However, there are some harmful fish species that you should avoid eating.
Unfortunately, due to human industrial activity such
as coal-fired electricity generation, smelting, and waste incineration, large
amounts of mercury end up in our waterways and subsequently in the fish that
swim in them.
Once this mercury enters the marine food chain, it
"bioaccumulates." This means that as the smaller fish gradually eat
the larger fish, the mercury concentration at each level increases.
Consuming too much mercury can be dangerous to your
health and lead to mercury poisoning. For this reason, the FDA and the U.S.
Environmental Protection Agency (EPA) have issued guidelines regarding the
amount of mercury that humans can safely ingest. In addition, the non-profit
Environmental Defence Fund (EDF) offered a list of harmful fish that are not
recommended to eat.
16 types of harmful fish that you should
not eat (or that you should eat less)
1. Tilapia
Tilapia is one of the most commonly consumed harmful
fish, but it contains very low levels of omega-3 and high levels of omega-6.
Which is related to high levels of inflammation in the body. Eating a diet with
an adequate ratio of omega 3 to 6 fatty acids is important when it comes to
treating chronic inflammation.
The main problem with most of the tilapia consumed is
that it is farmed, so it will not have the same nutritional profile as
wild-caught fish. A 2008 study revealed that current consumption of farmed fish
such as tilapia has led to increased consumption of inflammatory fatty acids.
2. Atlantic cod
The problem with Atlantic cod is less related to
health and more to the environment and fish population. Atlantic cod have been
heavily fished for a thousand years, and in the late 1990s the fishery
collapsed. The Atlantic cod fishery has declined dramatically since then, but
the species has struggled to recover.
Scientists agree that the collapse of the fishery has
fundamentally changed the North Atlantic food web, and the species is now
considered vulnerable to extinction.
3. Atlantic flatfish (halibut, flounder
and sole)
This is another case of overfishing and waste.
Commercial fisheries have what is known as “bycatch”. Which is when a fish or
other marine species are caught involuntarily while searching for other fish.
US fisheries dump about 2 billion pounds of bycatch each year. This equates to approximately half a billion meals.
4. Caviar
Caviar is the eggs of the beluga sturgeon, an ancient
fish that can live for a hundred years. Their eggs are highly sought after and
can be sold for thousands of dollars a kilo. Because of this, this very special
fish is also very vulnerable to extinction. The same is true for many other
types of sturgeon.
5. Chilean Sea Bass
Regarding the environment, this is another species
that has been subject to high overfishing. Besides that, it is one of the
harmful fish as its high mercury content represents a risk to human health.
6. Anguilla
This is a fish that you might want to avoid on the
sushi menu. Eels are slow to mature and have been overfished in many parts of
the world, causing some populations to collapse.
This is problematic because eels play an important
role in the spread of mussel populations, which act as natural water filters.
Also, eels absorb and store harmful chemicals and pollutants very easily. This
is such a problem that in some area’s residents are advised not to eat eel more
than once a year.
7. Farmed salmon
Most salmon are farmed, and farmed salmon can contain
higher amounts of harmful contaminants such as PCBs. Which are linked to a
variety of health problems such as insulin resistance, obesity, cancer, and
stroke, making it one of the harmful fish.
Farmed Atlantic salmon are also often treated with
antibiotics that make them richer in inflammatory omega-6 fatty acids.
8. Imported Basa, Swai, and Striped
Catfish
Most of the time, these fish are simply labelled
"catfish," and you should definitely avoid them. A 2016 study found
that between seventy and eighty percent of these fish were contaminated by
Vibrio Bacteria, which is what causes most cases of shellfish poisoning.
9. Imported farmed shrimp
There are a number of pesticides that are used
globally in shrimp production. All but one of them are banned in the United
States, for example. On top of that, these shrimps have often been treated with
large amounts of antibiotics. So, every time you handle these raw shrimps, you
run the risk of becoming infected with bacteria resistant to antibiotics.
10. Imported king crab
About three-quarters of all crabs sold in the United
States are imported from Russia, where unsustainable fishing practices are very
common. Technically, the only crab caught in Alaska is called "Alaskan
King Crab."
However, mislabelling these products is incredibly
common, so knowing where the crab came from is important. If it says
"imported" and "Alaska" on the label, something is wrong
and you should stay away from it.
11. Orange roughy
These fish can live for several decades and usually do
not reach sexual maturity until they are at least twenty years old. They are
another species that has been overexploited, but due to their very slow
breeding cycles, they have a hard time recovering.
Orange roughy is also known to have high levels of
mercury.
12. Shark
Since sharks are at the top of the food chain, they
have very high levels of mercury. These are also slow to mature and reproduce,
so overfishing has also reduced their populations.
13. Atlantic bluefin tuna
Bluefin tuna have been severely overfished and are now
considered to be very close to extinction. They are also large predatory fish
and therefore contain high levels of mercury.
14. Swordfish
This is another predatory fish, so once again, mercury
is the main concern in this case. In fact, EDF has recommended that women and
children avoid swordfish altogether and men consume it no more than once a
month.
15. King mackerel
Both king mackerel and Spanish mackerel have high
levels of mercury and should be avoided, especially in women and children.
16. Grouper
The grouper has moderately high levels of mercury and
is vulnerable to overfishing. It is also often the subject of seafood fraud.
The “grouper” that is for sale is often a cheaper form of fish that has been
intentionally mislabelled.
Whatever your option when it comes to eating fish,
consider these options, especially when they are near extinction or are
contaminated and derived from the sea. Nowadays, it is difficult not to find a
sea fish that is not contaminated, with high or low levels of mercury or other
harmful substances, and not to mention those that are the product of farms and
factories where they are fed and maintained in no way. healthy.
The lights are dim, you’re settled comfortably in bed, and the show is about to get started. At this point, the base of your brain is busy sending signals to the other areas of your brain that it’s time to stop making you feel awake and start powering down. You begin drifting in and out of sleep, and your eye and muscle activity start to slow down. You’re officially in Stage 1 of non-rapid eye movement (NREM) sleep. This is gonna be good! Brain C-13
