Children’s risk of developing attention-deficit hyperactivity disorder （ADHD） later in life may be tied to how much fish their mothers ate while pregnant, according to a U.S. study.
Researchers writing in the Archives of Pediatrics & Adolescent Medicine found that eating at least two servings of fish per week was linked to about a 60 percent lower risk of kids developing certain ADHD-like symptoms.
But elevated mercury levels, which can also come from eating more fish were tied to a higher risk of developing the symptoms, such as hyperactivity, impulsiveness and inattentiveness.
