Is it possible that your body is contaminated with mercury from eating fish?

Many times we hear about the benefits of eating fish, but it's not always that good. You should know that, beyond its valuable nutritional properties (such as proteins, minerals, vitamins of group B and omega-3 fatty acids), fish may contain metals, such as mercury.

This is indicated by a Spanish study conducted by the National Center for Environmental Health. Research indicates that Those who consume fish more than five times a week have risky levels of mercury in the body.

The research has been carried out based on almost 2,000 blood samples, 1700 urine and 600 hair samples from people residing in Spain. The results revealed that about 5% had higher levels of mercury than is considered adequate.

This would mean that, in Spain, 1 in 20 people could have a risky level of mercury in the body.

Mercury is considered by the World Health Organization as 1 of the 10 products or groups of chemicals that pose public health problems. It comes mainly from the consumption of fish and shellfish contaminated with methylmercury, an organic compound present in these foods.

There are different forms of mercury that are distinguished by their degree of toxicity and their effects on the nervous and immune system, the digestive system, the skin and other organs.

Tuna and swordfish are two of the species that accumulate mercury in their body from the smallest fish they ate and that, in turn, would have ingested it by feeding on plankton.

Since mercury is a metal that especially harms pregnant women and children, the Spanish Agency for Food Safety and Nutrition (Aecosan) recommends, for example, not to eat more than two cans of tuna per week.

As an alternative, proteins, minerals and vitamins can be supplanted with algae, legumes, whole grains, nuts and seeds.
