Are canned fish healthy? If you consume them regularly, we will also discover what are their nutritional benefits and aspects to take into account.

Although it is a fairly widespread myth among society, canned fish (worth the redundancy) do not contain preservatives of any kind because the sterilization process to which they are subjected is more than enough to keep all their properties intact.

All this without commenting that many of them offer a somewhat cheaper option than buying fresh fish directly. Thanks to this, many people can afford to buy canned fish in their nearest It should also be noted that the process of conservation and treatment  of this type of fish has a very low ecological impact since it does not need to be transported in cold rooms and its commercialization can be extended in time without any problem. Finally, canned fish are very easy to take anywhere (especially if we go on a trip) and can be stored in a cool and dry place for a couple of days without any problem.

In short, canned fish are a very healthy option to benefit from all the advantages of fish without causing our economy to become too destabilized. Once this is known, would you like to know more nutritional properties of these preserves? Well, through the following lines we tell you about it.

The benefits of canned fish

They are rich in Omega 3 acids

The truth that this could give for a separate article. The Omega 3 is a natural fatty acid  that contains many health benefits. First of all, it is a nutrient that improves our visual acuity, strengthens our nervous system and mitigates the symptoms of stress and anxiety.

Omega 3 is also beneficial for preventing certain cardiovascular diseases and increasing the levels of “good” cholesterol in the blood (HDL).

They contain vitamins A, D, B2 and B3

Canned fish are also an inexhaustible source of vitamin A, a nutrient that is essential to strengthen our entire immune system. All this while at the same time we will enjoy much stronger bones and teeth.

For its part, vitamin D improves the functioning of our nervous system and promotes the production of hemoglobin and red blood cells.

They are rich in minerals such as iron, zinc and iodine

Minerals such as iron, zinc and iodine are also very present in canned fish. The first of them is beneficial for concentrating and developing our cognitive functions.

Zinc supports our metabolism and keeps our hair, nails and skin as strong as possible.  Finally, iodine secretes the production of thyroid hormones and balances our body odors.

Aspects to consider with canned fish

It goes without saying that there are all kinds of fish that we can find perfectly preserved, such as tuna, sardines, clams, anchovies, razor clams, mackerel or melva among many others.

However, as with any food, a series of contraindications must be taken into account that we will report below.

  • They can be high in salt. Some preserves can be high in sodium, which in large quantities can have a negative impact on our cardiovascular health. Therefore, it is recommended to be very attentive in all those people who suffer from hypertension or high cholesterol.
  • Be careful with the packaging. Who has not ever cut themselves opening a can of preserves? We strongly recommend that you be very careful with this as you can make very deep cuts on your fingers or hands that will need immediate medical attention.

As we can see, canned fish can become a nutritious and healthy option to enjoy the different nutritional qualities that fish offers us. However, without forgetting that it is always more appropriate to choose to eat fresh fish.
