How much fish do you eat in a week? Study links one variety to skin cancer risk
When it comes to a healthy diet plan, even in the Mediterranean diet, fish is an important part of all. One of the richest sources of proteins and omega-3 fatty acids, fish is strongly linked to healthier, skin, hair, heart, body weight, and diabetes management. However, to the surprise of many, eating it too much could raise cancer risk. According to US experts, eating an excess fish may raise melanoma risk – one of the deadliest forms of cancer.
Experts discovered that those who age 43 grams of fish every day – approximately two weekly portions – were 22 per cent more prone to melanoma as opposed to those who rarely ate fish. Scientists believe that this is because of the pollutants found in seafood such as mercury, arsenic, dioxins, and polychlorinated biphenyls.
As per the National Health Service of England, two 140-gram servings of fatty fish a week should suffice. Experts also say that discontinuing fish intake is not recommended in this case. The study appeared in the Cancer Causes & Control journal.
Which variety of fish can raise cancer risk?
The authors of the study said that a high intake of non-fried fish and tuna can raise melanoma risk. Experts say that a balanced diet must include fish. The negative effects of excess fish intake can be mild but can get worse over time if timely action is not taken.
Fish intake is not the only contributing factor to melanoma – excess exposure to the sun, and not using sunscreen could also be linked to cancer risk.
