Consumption of fish and fish products has many benefits for human health. However, it turns out that canned ones are devoid of many useful nutrients, which contributes to the harm of their intake.
Tuna is very rich in protein, omega-3 acids, iodine, iron and B-group vitamins. However, in cases of excessive intake, especially from risk groups - pregnancy and young age, you must be very careful.
Canned tuna is proven to be very high in protein, with just one tin providing 50% of the daily requirement. But it is very important to be careful eating tuna often.
Also stored in this way, the fish product is poorer in omega-3 fatty acids than fresh fish. We know that the presence of fish delicacies in the menu is important for the proper functioning of the cardiovascular system, as well as for the maintenance of healthy skin and hair.
Another disadvantage of canned tuna consumption is the presence of a lot of sodium (salt). Naturally, sodium in certain amounts is necessary for human health, but its excess leads to serious health deviations. Such are the retention of fluids in the body, which leads to an increase in arterial pressure. For this reason, people with high blood pressure should limit their intake of canned fish.
And if you're tempted to buy at least one, read the contents carefully first for the presence of sodium, mercury, sugar, and more.
Mercury is something that a pregnant woman and children should be very careful with. If taken in large doses, it becomes toxic and very dangerous for humans.
Canned tuna contains high amounts of methylmercury, which is a dangerous neurotoxin that accumulates in individual organs and tissues (brain, kidneys, etc.). Symptoms of mercury poisoning are a feeling of numbness in different parts of the body, tremors, difficulty walking, problems with vision, memory. The danger is also very great for the unborn child, still in the womb of the woman.
Canned tuna also contains the compound Bisphenol A, or more precisely in the packaging. The danger comes from the fact that it passes into the composition of the fish. It has a negative effect on the brain, as well as being very dangerous during pregnancy and for small children.
