The government is putting out new guidelines for eating fish, over fears mercury in fish poses a hazard to youngsters.
The Food and Drug Administration says women who are pregnant, nursing, or may become pregnant, and young children, should not eat certain kinds of fish that tend to be high in mercury.
They include shark, swordfish, king mackerel and tilefish. On the other hand, the guidelines suggest eating up to two meals a week of fish known to be low in mercury, such as canned light tuna, salmon, Pollock, and catfish, along with shrimp.
While mercury can affect almost any organ in the body, the FDA says the most sensitive organ is the brain. The big concern is there could be a mental effect on a young child.
At the same time it issues the guidelines, the FDA stresses that fish is a good source of protein and other nutrients, particularly omega-three compounds that can benefit the heart.
