6 Kinds of Fish You Shouldn’t Eat

6 Kinds of Fish You Shouldn't Eat

Various studies have been published for many years confirming the presence of heavy metals in fish. Among these heavy metals, a significant proportion is methylmercury. This is a very dangerous component for humans.

However, mercury is not the only thing that can affect human health. There is another harmful compound in fish oil. These are dirty particles from the fish environment.

Objects such as plastic or strong chemical elements infect the fish, which ends up on the table as a healthy meal.

In addition, the human body cannot process elements such as mercury. Metal accumulates before reaching dangerous levels.

Knowing that there are certain species of poisonous fish, we must also understand which species of fish are most affected by mercury. We will list them below.

1. Red tuna

Red tuna is one of the most popular fish species in the fishing industry. There are many types.

Due to the dangers of mercury, people cannot regularly eat red tuna. This warning applies in particular to children and pregnant women.

This fish can be eaten a maximum of once a week.

2. Pangasius

In the list of the most dangerous species of fish in the world, we find pangasius. It originates from Vietnam and is gaining popularity because it is easy to cook.

Because it has no bones, it is easy to eat. Like flounder, you can also eat it as a fillet, but pangasius is cheaper.

Despite the lightness and price, it lacks nutrients. Pangasius contains little omega-3 fatty acids.

In addition, a pesticide known as trifluralin contaminates this fish. It is a substance that can be harmful to human health.

3. Black Sea blenny

This fish is one of the most common in Spanish cuisine. It is even used as a cheap alternative to swordfish. However, its large size is a major drawback.

Due to its size, fat accumulates cadmium (a harmful metal) and mercury. Both metals do not have health benefits, so the best option is to avoid consuming them.

4. Mackerel

Many places regularly consume mackerel, especially in restaurants. Despite its popularity, the World Health Organization (WHO) recognizes it as dangerous.

This dangerous fish contains one of the highest amounts of mercury in its meat. Therefore, you should avoid mackerel or at least eat it only occasionally.

5. Tilapia

If mackerel is popular, what about tilapia? It is undoubtedly one of the most popular fish species for fishing, trade, and consumption.

Despite its prevalence, it can also be one of the most dangerous fish for human health. Even worse, tilapia is even compared to lard due to its high content of fat. This leads to high cholesterol levels, or in other words, the bad cholesterol.

With this in mind, you should try to eat as little tilapia as possible, especially if you have arthritis, asthma, or heart disease.

6. Swordfish

Due to its large size, the swordfish feeds on other smaller fish for life. As a result, it accumulates large amounts of fat, which may also contain high levels of mercury.

Given these high levels, you better not eat swordfish and eliminate it from your diet.
