It is said that fish is a good thing, rich in high-quality protein and low in fat content. It is white meat highly recommended by nutritionists.
However, picking fish is also a technical job, so you can take it easy when buying the following kinds of fish.
First: fish that are too big or too small
Many people like to choose a big fish to buy.
In fact, for the same species of fish, if the size is too large, the fish is generally older, the meat quality may be coarser, and it may also enrich more environmental pollutants.
Of course, you don’t have to worry too much about eating big fish, which will definitely be harmful to your health. Most of the pollutants in the fish are within a safe range and you can eat them at ease.
Is it necessary to choose small fish to buy?
Nor is it.
Although there is no what problem for the safety of fish that are too small, many fish have not yet grown up and matured due to their small size, and the aroma substances in their bodies are relatively small, so they do not taste so fragrant.
In addition, there are few small fish, which makes it difficult to satisfy our appetite.
The second species: large carnivorous fish
Large carnivorous fish are more likely to accumulate harmful substances such as heavy metals in their bodies. International authoritative health institutions also recommend not to eat large fish such as sharks, swordfish, sailfish and square head fish.
We have all heard the saying [big fish eat small fish, small fish eat small shrimps, small shrimps eat mud].
In fact, this is the typical food chain in aquatic environment.
The higher the level of the food chain, the more harmful substances accumulate in the body, while the larger the carnivorous fish, the higher the level of the food chain, and the greater the impact on health if eaten.
The third kind: fish sold in small stalls
We may have all bought fish in some irregular vendors for convenience and for cheap.
Not that the fish on the stalls must be bad, but that some irregular vendors cannot guarantee the source and quality of the fish, which may hide greater potential safety hazards, such as excessive heavy metals and parasites.
If you want to eat fish at ease, you should go to regular supermarkets and food markets to buy it.
The fourth species: wild fish that are infatuated with
Many people like to eat some wild fish to relieve their cravings.
In fact, due to the uncertainty of environmental pollution, wild fish may be more likely to enrich some completely unexpected toxic substances.
For example, many fish will accumulate toxins in their bodies due to predation of toxic seaweed, small fish and shrimps, such as ciguatoxin and tetrodotoxin. Once people eat them, they will easily be poisoned or even endanger their lives.
Don’t be infatuated with wild fish, it is only a legend.
The fifth kind: pickled fish
Many people like to eat pickled salted fish. However, the International Agency for Cancer Research (IARC) has listed Chinese salted fish as the first carcinogen and must eat less.
This time, the salted fish really can’t turn over…
The report “Diet, Nutrition and Prevention of Chronic Diseases” issued by the Joint Expert Group of the World Health Organization and the Food and Agriculture Organization of the United Nations clearly points out that:
Chinese salted fish can cause cancer, and regular eating of salted fish will increase the risk of nasopharyngeal carcinoma.
However, this does not mean that we cannot eat salted fish at all. It is OK to eat it occasionally, but we must eat less.
What? You asked which kind of fish to buy?
The answer is: everything can be eaten except what cannot be eaten.
Then the question arises, among those fish that can be eaten, how can one choose a fresh fish?
How to choose a fresh fish?
Fish is healthy, but if it is not selected well, it is neither fresh nor delicious, and may not be safe. How can we choose fresh and safe fish?
The U.S. Food and Drug Administration (FDA) recommends:
Step 1 Smell
Try not to buy fish that smells sour and ammonia.
Step 2 Look at the fish’s eyes
Try to buy fish eyes that are clean and bright, with a little bulging fish.
Step 3 Look at the gills
Try to buy fish with bright red gills.
Step 4 Look at the back muscles
Try to choose fish with elastic back (bent to retract).
5. If you buy frozen or refrigerated fish
Try to choose those meat that are not dark or black in color.
Speaking of which, many friends may worry that frozen fish is not good. In fact, it is generally recommended to buy live fish, which is fresh in meat quality, high in safety and good in taste.
However, if it is a regular processed quick-frozen fish, its nutritional value is no worse than that of fresh fish, so you can eat it at ease.
Frozen fish actually provides a kind of convenience for our life. After all, many people are not convenient to go out to buy and kill fish every day.
Of course, if you don’t think these methods are very easy to operate or don’t want to spend this time, the most effective way is to go directly to regular supermarkets or markets to buy them.
Finally, Dr. Clove couldn’t help gossiping…
It is said that catfish is the dirtiest fish in the world, [eating animal excrement and loving to live in dirty water].
Nothing! It is only more adaptable to harsh environment than some delicate fish.
What, be strong, is catfish wrong?
For so many years, as strong salted fish, why can’t we understand more about the same strong catfish?
