To eat fish is very important. It is a healthy, light food rich in beneficial substances for the body such as the precious omega 3 and 6 fatty acids, antioxidants that counteract the action of free radicals on aging and abnormal cell multiplication, responsible for tumor formations.
The fish it is rich in phosphorus, important for the brain, which improves memory and concentration.

In most cases, however, it is customary to consume in particular canned tuna, both for economic and convenience reasons. In fact, it is a usual gesture to take a can of tuna from the fridge, open it easily with the tongue of the tin and pour the food, dripping it in excess oil, in a dish to taste it ready. Tuna can also be added to salad or pasta. However, there are those who firmly say:“Don’t eat canned tuna.” Here are the possible consequences if we do.
The dangers of canned tuna
Who says it is dangerous to eat canned tuna refers to the high content of sodium of the product. A can of tuna can in fact also contain more than 600 milligrams of sodium, which is purely used as a fish preservative and to increase its tasty flavor. However, excess sodium is harmful to health: it can increase blood pressure and lead to embolism.
Another problem with canned tuna is the absorption of heavy metals. Tuna fish eat smaller fish so they end up introducing heavy metals like mercury into their body. And when we eat tuna, the same thing happens to us. Even a small amount of mercury can damage our digestive system, the immune system, the kidneys and the skin. High amounts of mercury can increase the risk of heart attacks and cause brain damage.
But it’s not over. The oceans are highly polluted, full of toxic products that fish consume passively. These substances are therefore found as carcinogens present in the fatty layer of many fish such as the tuna. Finally, tuna fishing has a negative impact on the natural ecosystem. Unfortunately, tuna is not the only fish that remains trapped in fishing nets. Sharks, dolphins and other animals also end up in slaughter along with tuna.
