Fish not so healthy after all

Even little knowledge about healthy nutrition is enough to be aware that fish are one of the most nourishing types of food. They are a rich source of omega-3 acids, vitamins, protein, mineral nutrients and microelements including the ever important iodine.

 

After you become more familiar with the fish topic, it turns out that one fish is not equal to another. Of course freshwater fish have other qualities than sea fish; differences can also be seen between particular species. There are, however, some species that definitely should be avoided. And a fish called panga leads the way.

In truth, in Poland the term ‘panga’ denotes a few species of fish, but most often shark catfish. It is a freshwater fish from Asiatic rivers. However, the specimens sold in our shops usually do not come from river fishing but from breeding. That is because panga seems to be a very rewarding breeding species – it has low requirements and quickly gains weight, reaching even several dozen kilograms. 

The Vietnamese specialise in breeding pangas. However, breeding conditions in which the fish live, leave much to be desired. These fast-growing fish are often kept in much too small tanks - they cannot move freely, but also live in polluted water, which contributes to their being cooped up together. What is more, breeders, to minimise the risk of financial loss, stuff them with food products full of antibiotics. Pangas are also fed with hormones, which are supposed to force them to reproduce in breeding conditions and chemical-rich nutrients are used to ensure the fastest weight growth.

As a consequence, pangas from fish farms are not only worthless for our diet, since, apart from salt and water, the only ingredient in their meat is protein, but also they can also be harmful with regard to e.g. heavy metal content. Despite all this, it is a very popular fish in Poland – panga fillets are cheap, have no bones and their meat looks simply nice thanks to its light colour. However, you have to be aware that panga consumption not only will not provide nourishing substances, but can lead to health problems, so the fish should be eaten in moderation and in case of small children should be totally avoided in diet – unless we are sure that the fish we bought does not come from a fish farm.
