The amazing health benefits of fish

The consumption of fish is common in many countries of the world, not only because of its convenience, but also because of its great health benefits.

So what is “fish”?

As you know, fish are aquatic creatures with gills and fins instead of limbs. The total number of the fish group is about 32,000 different species, including predators. A rich in fish diet is very healthy, as some species are whole “storehouses” of nutrients and essential fatty acids. Despite the wide variety and distribution of these creatures in the world’s oceans, lakes, and rivers, only a small percentage are regularly consumed by humans.

Nutritional value

When it comes to nutritional value, saltwater fish can provide high levels of vitamin D, vitamin B12, selenium and protein along with high concentrations of omega-3 and omega-6 fatty acids, which are essential for human health. Nutrient content will vary greatly among fish species: some of them can be healthy, while others may result harmful due to the presence of heavy metals.

Health benefits 

There are interesting health studies related to regular fish consumption, which can reduce the risks of depression, autoimmune diseases, and even PMS (Premenstrual Syndrome) symptoms. Below are listed some benefits associated with fish consumption:

  • Metabolism acceleration, which improves weight loss

How should fish be stored?

Once a fish has been caught or purchased, it is important to know how to properly preserve it in a safe and healthy manner.

  • Cooked fish: after cooking, fish can be stored for 3-4 days. However, it is best to eat it the same day immediately after cooking.
  • Smoked fish: To avoid food poisoning, smoked fish should be kept in the refrigerator no more than 4-5 days. Be sure to pack it hermetically in plastic food wrap.
  • Fresh fish: Most refrigerators cannot preserve the flavor or aroma of the fish overnight. You can do this by using food ice or ice packs that you wrap the fish around to keep it at a low temperature. This will keep it fresh and preserved for days to come.
  • Frozen fish: If you want to freeze fresh fish, make sure it is not wet and then place it in the freezer.
