It is true that tuna is a very healthy food, and that it has many benefits and properties, but did you know that an excessive consumption of tuna can have contraindications? This is because they are large specimens, and with a long life. They live for many years. In addition, added to the fact that it is a great predator, we can find high amounts of mercury, among others.
The contraindications of a high consumption of tuna, mercury
As we said, tuna is very beneficial, but always in the right measure. In fact, it is recommended to eat oily fish up to twice a week. But we should vary the fish we eat.
In the case of tuna, in large specimens we can find mercury. A mineral that, in high quantities, is very toxic and also interferes with neurological development. That is why it is recommended to restrict the consumption of this fish to pregnant women and children.
In addition to mercury, tuna also contains high amounts of histamine, a derivative of fish proteins. In large quantities, this can cause allergic reactions.
But regardless of the amount, it can cause intoxication in hypersensitive people.
Other contraindications for specific cases
In addition to the above contraindications of tuna, which are applicable to all people, there are others that we have to take into account.
For example, smoked or dried tuna is not suitable for people suffering from hypertension. Because they are elaborations with a high salt content, something not at all favorable for high blood pressure.
In addition, it is a very fatty fish, so it is important to take this into account if we suffer from certain health problems.
And of course, in case of allergies or intolerance to any of the components of tuna, we should avoid its consumption.
These contraindications are exactly the same for both fresh tuna and canned tuna, of which, it is not recommended to consume more than two a week.
