Fish is a delicious food that is recommended for consumption and is widely appreciated, especially in many diets that are currently popular. But eating fish may not be as healthy as you think, as a study linked it to skin cancer.

disturbing discovery

Fish is a food source that is gaining more and more followers, especially thanks to the popularity of some diets, such as the Nordic diet and the Mediterranean diet. The fish in these diets are particularly excellent alternatives to consuming red meat and likely offer a wide range of health benefits, as fish is very rich in nutrients, such as vitamins, minerals and fatty acids.

But it seems that eating fish on a regular basis is not as good for your health as you might think. According to a new study by researchers from Brown University and the National Cancer Institute in the United States, only consume Two servings of fish a week linked to skin cancer. The results of the study were surprising, as eating fish is generally recommended for the prevention of certain types of cancer. Also, melanomas are logically related to risk factors such as sun exposure or genetic background.

A problem that can be attributed to some pollutants ingested by fish

However, a link between skin cancer and fish consumption has been demonstrated, and more studies will be needed to learn more about this. It’s really important to know that the study didn’t identify the cause of this strange association. However, researchers have some theories about this. ” We speculate that our findings can be attributed to contaminants found in fish, such as PCBs, dioxins, arsenic and mercury. Said Eunyoung Cho, lead author of the study, in a statement.

To reach these conclusions, researchers surveyed 491,367 Americans between the ages of 50 and 71 over a period of more than 15 years. In particular, they assessed how many of them developed melanoma, an aggressive form of skin cancer. Data obtained on skin cancer were compared with fish consumption data for study participants. The results of the study published in the journal Cancer causes and control revealed that people who eat more fish are actually more likely to develop skin cancer.

Specifically, people whose daily fish consumption was 42.8 grams (or about 300 grams per week) had a 22% greater risk of developing skin cancer of those who only ate 3.2 grams per day. The results also showed that those who ate more fish were 28% more likely to develop abnormal cells in the outer layer of the skin, known as melanoma in situ. In the face of these disturbing findings, the researchers wanted to clarify that this in no way diminishes the health benefits of eating fish.
