It’s refreshing to see public acknowledgement that eating fish — even for pregnant women — is generally healthier than not eating fish (“Study clouds pregnancy-seafood issue,” March 9). But it’s not this recent British study that has “clouded” the issue.

That dishonor goes to environmental advocates who have placed their own agendas — usually involving small amounts of mercury emitted during the generation of electricity — ahead of the public’s health. By scaring women away from eating fish, they have needlessly put children in harm’s way.

It’s also exciting news that pregnant women who eat the most fish, mercury and all, end up with the smartest children. I guess our moms were right: Fish really is “brain food,” after all.
