Fish Intake During Pregnancy Increases Risk for Childhood Obesity

High intakes of fish during pregnancy increase the risk for overweight and obesity in offspring, according to a study published online in JAMA Pediatrics. Researchers monitored 26,184 women and their children for fish intake and BMIs, respectively. Those who ate fish more than three times per week while pregnant had children with higher BMIs through early childhood and increased their children’s risk for rapid weight gain when compared to those who ate less fish per week. Researchers suspect chemical pollutants found in fish may alter fat metabolism and thus contribute to weight gain.
