Types of unusually large fish
Many of us are often attracted to and enjoy eating unusually large fish because we think they are more meaty and nutritious. But each type of fish has a certain weight, and if you find a fish that is larger and older, the level of heavy metal pollution is higher. Other factors contribute to fish containing heavy metals, including the species of fish, the habitat of the fish, its diet, and its living environment. Fish species that are at the top of the ocean food chain tend to contain more mercury. Examples include swordfish, king mackerel, tilefish, sharks, and kingfish… Additionally, if farmed fish are abnormally large, it indicates that they must consume a lot of growth-promoting substances to reach such excessive sizes.
These carnivorous fish are large in size and tend to absorb all the heavy metals from the smaller fish they eat. When humans consume these types of fish, the heavy metals in the fish’s body will also be transferred to their own bodies, causing a burden on the liver. In addition, regularly eating growth-promoted fish can lead to rare diseases that affect human growth.
Fish with special odors
If you go to the market to buy fish and you smell a petroleum odor, you should not buy it because it can live in a polluted water environment, which not only affects the taste but also exceeds the standard for heavy metal levels in fish, causing harm to the liver.
Instead of buying the above two types of fish, experts recommend choosing shellfish, including shrimp, lobster, and oysters, canned salmon, salmon, tuna, carp, and pomfret. In addition, when going to the market to buy fish, you should choose fresh, healthy fish with a strong characteristic smell. Therefore, when going to the market, if you are invited to buy extremely cheap fish, you should be cautious because there is nothing in this world that is suddenly good and cheap. Don’t be tempted by cheap prices at the expense of your health.
Fish living in polluted environments
Fish that usually live in polluted environments are prone to eat foods that contain lead and mercury, causing their bodies to have higher levels of heavy metals than normal. When you regularly consume these types of fish, you are at risk of being poisoned by lead, mercury, and other heavy metals. Over time, they will affect your liver, kidneys, as well as your body’s organs, causing dangerous diseases such as cancer. Therefore, you should stay away from fish that often live in polluted environments such as prisons, polluted rivers, and lakes to ensure your own safety.
