Eating canned tuna can cause these diseases

Mercury is naturally found in the environment, but it can also be expelled into the air through pollution, for example, through pesticides. In this way it reaches the water and is absorbed by the fish through its scales, its skin, or by feeding on other organisms, accumulating in their bodies. This type of mercury (methyl) can accumulate in greater quantities in some species of fish and shellfish that then consume other animals and people.

According to the World Health Organization (WHO), exposure to mercury is dangerous for intrauterine development, and can be toxic to the nervous and immune system, the digestive system, skin, lungs, kidneys and eyes.

Canned tuna contains mercury and can be harmful to the nervous system, especially in its stage of development. In California, the Office of Evaluation of Environmental Health Risks (OEHHA) recommends not to exceed eating tuna twice a week and replacing it with other low mercury fish such as trout, sardines or cod.

In this same line, the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA), both from the United States, advise that women of childbearing age, pregnant women, infants and young children avoid eating some types of fish and those that choose the others, low mercury: shrimp, salmon, gado or pollack and catfish.

In this way they can take advantage of the benefits of fish for the diet: high quality proteins, low saturated fats and omega 3 fats, which help heart health and growth and development, especially the smallest.

These organisms recommend not eating shark, swordfish, mackerel, or lofolátilo since they contain high levels of mercury.

The expert in nutrition Fernanda Alvarado explained in dialogue with El Universal that it is advisable eat the tuna along with foods like cilantro or parsley. Also, it is preferable to choose those who come "to the water", and avoid the preparations, since they also raise the sodium levels. All this, to protect yourself from the accumulation of mercury.

In the water there may be other contaminating substances besides mercury. For example, dioxin and polychlorinated biphenyls (PCBs), carcinogenic substances, are present in some types of fish. Do not forget that the oceans are increasingly contaminated by plastics that, when degraded, give off chemicals that negatively affect the entire marine ecosystem that we then feed on.
