These Are The Types Of Fish You Should Avoid

2000

We all know that fish is both delicious and healthy. However, there are certain fish that will do you more harm than good. These are the 9 types of fish you should avoid.

Catfish

Catfish can grow to considerable size. To accelerate their growth, many fish farmers feed them hormones, especially those fish imported from Asian countries. Free-grown catfish are much less dangerous and more nutritionally valuable.

Mackerel

Mackerel contains mercury, which is not cleared from but accumulated in the human body, causing various diseases. The Atlantic mackerel is the least dangerous in this regard, and you can eat it as much as you like.

Tuna

Tuna contains lots of mercury, especially blackfin and bluefin tuna. Additionally, there’s precious little free-grown tuna in the stores because it’s nearly extinct. All the fish comes from farms where it’s fed with antibiotics and hormones.

Tilapia

There aren’t many healthy fatty acids in tilapia, yet the concentrations of harmful fats in it are almost as high as in lard. Excess consumption of this fish leads to an increase in cholesterol levels and makes the body more sensitive to allergens.

Eel

Eels have lots of fat, and thus easily absorb industrial and farm waste in the water. American species have the highest level of such intoxication. European eels are also known for being contaminated with large amounts of mercury.

Pangasius

Most of the pangasius we see in our stores is brought from Vietnam, namely from the Mekong River that is considered one of the most contaminated water bodies in the world. Moreover, pangasius fillet contains an elevated level of nitrofurazone and polyphosphates (carcinogens).

Tilefish

This fish is the leader in mercury contamination, and it’s often caught in breach of the rules, increasing the risk of food poisoning.

Sea bass

Sea bass contains an ample amount of mercury. Sometimes, especially when it’s served as fillet, instead of sea bass you get pangasius or some other cheaper fish.

Dollarfish

This fish, more commonly known as oilfish, contains gempylotoxin — a waxy substance that is not metabolized at all. The toxin doesn’t do much harm, but it can cause indigestion. To reduce the levels of gempylotoxin, the fish should be fried or grilled.

HOW TO CHOOSE FRESH FISH

Fresh fish always has shiny scales and clear eyes. Take a fish in your hands and look — a spoiled fish will have its tail lowered weakly. Dry fins and gray gills instead of bright red ones also point to staleness.

When buying live fish from a tank, make sure the water is clear. Choose fish that aren’t near the surface but closer to the bottom.

If you like fishing and then cooking the catch, check the water for mercury. It’s simple to do when you have a mercury analyzer.

When buying salmon, choose chunks with white threads in them: if a chunk is completely red, it’s probably been dyed. Also, don’t take fish that has bright spots on its skin: it was caught during the spawning season, and its meat is bland.
