Eating 200 grams of canned tuna a day: crazy, that’s what happens

Statistics in hand, tuna is one of the types of fish-based food most consumed by the European and world population, for very different reasons and which are now well known: tuna is a very widespread variant fish (even though it is dwindling, becoming almost a form of endangered species due to long unregulated fishing), the animal’s body is largely made up of the edible part and is rather easy to consume and keep even at home.

Being an excellent “emergency” food, but also excellent for consuming a portion of fish. In Italy, canned tuna constitutes about 25% of the weekly fish consumption per household, although nutritionists recommend a dose that is not excessive. What happens if I eat more than the average amount, corresponding for example to 200 grams per day?

Eating 200 grams of canned tuna a day: crazy, that’s what happens

The recommended daily dose of canned tuna is not so small, as it corresponds to 50-60 grams, and in an even broader sense, the weekly dose should not exceed 170 grams, as recommended by the World Health Organization health.

The reasons are not inherent to the tuna itself, but to the presence of metals which naturally make up the animal’s body, in particular mercury which is tolerated in reduced doses, corresponding to the aforementioned limit. The mercury is extracted from the tuna itself.

It is also important to consider the addition of salt and other preservatives that have a function both related to the long-term preservation of canned tuna but also related to flavor. As we know, too much salt contributes to a series of problems such as increased blood pressure. It is therefore absolutely inadvisable not to exceed in consumption and not even to come close to the 200 grams mentioned above for people suffering from hypertension.
