" The benefits of eating a diet rich in fish outweigh the risks, scientists have said.  Previous studies have suggested that mercury in some fish, such as salmon, could be dangerous, but scientists from Oregon state university say that this should not put people off eating seafood.  In a ten-year study, scientists from Rochester medical school looked at the diets of 700 children living in the Seychelles. The children ate an average of 12 fish-based meals a week - around ten times the average consumption of Americans.  All of the fish the children ate contained high levels of potentially harmful methylmercury. However, in tests on the children&amp;#039;s brains, the team found no defects normally associated with mercury absorption.  However, lead researcher Professor Michael T Morissey said that pregnant women and children should still follow guidelines which say these groups should avoid eating shark, tilefish, swordfish and Spanish mackerel.  &amp;quot;But young children and pregnant women should still eat 12 ounces a week of a variety of fish to be sure to get the important nutrients - especially omega-3 fatty acids,&amp;quot; he said.  &amp;quot;For the rest of us, I would recommend eating fish four to seven times a week. The evidence still suggests that seafood plays a role in reducing coronary heart disease - and new studies suggest that it may reduce the onset of Alzheimer&amp;#039;s as well as other mental illnesses,&amp;quot; he added.  Professor Susan Carlson from Kansas university medical centre said that even though pregnant women should choose their fish carefully, nutrients found in fish oil had been previously linked to a healthy brain and good sight in breast-fed infants.  In the UK, the government advises individuals to eat at least two portions of fish a week, one of which should be oily, such as salmon or mackerel. \u00A9 Adfero Ltd "^^<http://www.w3.org/2001/XMLSchema#string>
