Fish, Mercury and The Brain: high levels of mercury can cause neurodegeneration and brain damage

Article by Michael Gonzalez-Wallace and Nutritionist Olinka Podany MS, RD

MERCURY

(high levels of mercury can cause neurodegeneration and brain damage)

Nearly all fish and shellfish contain traces of mercury. But some contain high levels. Eating large amounts of these fish and shellfish can result in high levels of mercury in the human body. In a fetus or young child, this can damage the brain and nerves (nervous system).

IMPORTANT INFORMATION

Because of the mercury found in fish, the U.S. Food and Drug Administration (FDA) and U.S. Environmental Protection Agency (EPA) advise the following people to avoid eating fish high in mercury and to eat limited amounts of fish and shellfish that are lower in mercury:

Women who may become pregnant

Pregnant women

Nursing mothers

Young children

If you are concerned about your or your child’s mercury level, talk to your doctor or local health department about testing.

EATING HABITS

How should you change your eating habits to reduce your exposure to mercury in fish?

The FDA and EPA recommend that women who may become pregnant, pregnant women, nursing mothers, and young children:1, 2

RECOMMENDATIONS

Do not eat shark, swordfish, king mackerel, or tilefish, because these all contain high levels of mercury.

Eat up to 12oz a week (two average meals) of a variety of fish and shellfish that are lower in mercury.

Five of the most commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock, and catfish.

Another commonly eaten fish, albacore (“white”) tuna, has more mercury than canned light tuna. So when choosing your two meals of fish and shellfish, you may eat up to 6oz a week (one average meal) of albacore tuna.

Check local advisories about the safety of fish caught by family and friends in your local lakes, rivers, and coastal areas. If no advice is available, eat up to 6oz a week (one average meal) of fish caught from local waters, but don’t eat any other fish during that week.
