Study: eating fish while pregnant may result in risk of ADHD in child

BOSTON, Mass. -- Pregnant women need to consider both the benefits and risks of eating fish when it comes to ADHD.

Researchers measured mercury levels in hair samples of about 400 new mothers, then followed up with their children eight years later.

Mothers with higher mercury levels were more likely to have children with attention and hyperactivity problems, even though the levels were not considered hazardous.

However, there was a reduced risk of ADHD behaviors in children whose mothers ate more than two servings of fish a week.

Although the study didn't look at what types of fish are best for pregnant women, flounder, haddock, and salmon are low in mercury.

Shark, swordfish, and fresh tuna have higher mercury levels.

This study was led by researchers at Brigham and Women's Hospital and published in 'Archives of Pediatrics
& Adolescent Medicine'.
