Canned fish: Nutritious benefits
Although it is a widespread myth among society, canned fish (worth the redundancy) do not contain preservatives of any kind because the process of sterilization to which they are subjected is more than enough to keep intact all their properties.
All without mentioning that many of them offer a cheaper option than buying fresh fish directly. Thanks to this, there are many people who can afford to buy canned fish at their nearest supermarket without having to scratch their pockets too much.
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 stores and its commercialization can be extended over 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, dry place for a couple of days without any problem.
In short, canned fish are a healthy option to benefit from all the advantages of fish without our economy being too destabilized. Once you know this, would you like to know more nutritional properties of these preserves? Well, through the following lines we tell you.
Benefits of canned fish
Rich in Omega-3 acids
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 in preventing certain cardiovascular diseases and increasing the levels of “good” cholesterol in the blood (HDL).
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.
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 one is beneficial to concentrate and develop our cognitive functions.
Zinc favors our metabolism and keeps our hair, nails and skin from getting stronger. Finally, iodine secretes the production of thyroid hormones and balances our body odors.
Aspects to take into account with canned fish
Needless to say, there are all kinds of fish that we can find perfectly preserved as is the case with tuna, sardines, clams, anchovies, razor clams, mackerel among many others.
However, as with any food, we must take into account a series of contraindications that we will be reporting below.
- These can have a high salt content. Some canned fish can have a high sodium content, 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 suffering from hypertension or high cholesterol.
- Beware of packaging. Who has not been cut at any time by opening a tin? We strongly recommend that you have to be very careful with this since 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 consume fresh fish.
