British study debunks mercury in fish risk for pregnant women

Seafood News

New research from the Children of the 90s study at the University of Bristol suggests that fish accounts for only seven per cent of mercury levels in the human body.

In an analysis of 103 food and drink items consumed by 4,484 women during pregnancy, researchers found that the 103 items together accounted for less than 17 per cent of total mercury levels in the body.

Concerns about the negative effects of mercury on fetal development have led to official advice warning against eating too much fish during pregnancy. This new finding, published today in Environmental Health Perspectives, suggests that those guidelines may need to be reviewed.

Previous research by Children of the 90s has shown that eating fish during pregnancy has a positive effect on the IQ and eyesight of the developing child, when tested later in life. Exactly what causes this is not proven, but fish contains many beneficial components including iodine and omega-3 fatty acids.

After fish (white fish and oily fish) the foodstuffs associated with the highest mercury blood levels were herbal teas and alcohol, with wine having higher levels than beer. The herbal teas were an unexpected finding and possibly due to the fact that herbal teas can be contaminated with toxins. Another surprise finding was that the women with the highest mercury levels tended to be older, have attended university, to be in professional or managerial jobs, to own their own home, and to be expecting their first child.

Overall, however, fewer than one per cent of women had mercury levels higher than the maximum level recommended by the US National Research Council. There is no official safe level in the UK.

Eating Fish While Pregnant Halves the Risk of ADHD

The amount of fish a woman eats while pregnant may affect her child’s chances of developing attention-deficit/hyperactivity disorder (ADHD).

Eating fish twice a week was linked to about a 60 per cent lower risk of a child developing certain ADHD-like symptoms, according to research from the Boston University School of Public Health.

But the type of fish eaten is key.

Elevated mercury levels, which can occur from eating certain types of fish, such as tuna and swordfish, were also tied to a higher risk of developing ADHD symptoms such as a short attention span, restlessness or being easily distracted.

‘The really important message is to eat fish,’ said assistant professor Sharon Sagiv, the study’s lead author.

“…while many worry that overfishing has depleted much of the world’s fish stock, “fish stocks worldwide appear to be stable, and in the United States they are rebuilding, in many cases at a rapid rate,” according to a recent¬†New York Times Op-Ed piece by Ray Hilborn, a professor of aquatic and fishery sciences at the University of Washington. Even if this were untrue and fish were scarce, pregnant women would still be the most deserving recipients of this dwindling resource — and should be absolutely the last group to have to give up fish.”
