Scientists from the United States recently announced the results of his research to ward off the anxiety of consumers to consume sea fish. From the results of their research known to contain mercury in marine fish are still safe for health.
"Our research results show levels of mercury in marine fish from the waters of the United States and other countries is safe and not toxic to the heart as it feared all along," said Dariush Mozaffarian, lead researcher and cardiologist at Harvard Medical School.
In that study, fish consumers are exposed to high levels of mercury have an increased risk of heart attacks and strokes lower than the lower mercury exposure.
Methylmercury from industrial waste into the fish body through the food chain. The higher levels of the food chain, the higher the levels of pollution. Big fish like tuna that eat small fish will have higher mercury levels. On the other hand, in human food pyramid occupy the highest position.
For years, health experts recommend that pregnant women, nursing mothers and young children to limit fish consumption because it found a link between exposure to mercury with a delay of brain development in infants and children.
In a study conducted Mozaffarian and his team, they measured levels of mercury than 3427 pieces of nail people who have a history of heart disease, heart attack or stroke, and compared with residents who had no heart problems. Cuts nail is a common way used to measure exposure to mercury.
The results found mercury concentrations that are similar in both groups, 0.23 compared to 0.23 micrograms per gram. Levels of mercury are classified highest safe limit for pregnant women and infants was 0.4 micrograms.
The researchers also found no link between mercury exposure with the risk of heart disease and stroke, even in people with mercury concentrations above 1 microgram per gram.
