Omega-3 fatty acids found plentifully in fish contributes to the healthy neurological development of the fetus. Eating too much fish during pregnancy can raise a fetus's obesity risk which may result in preterm birth, a new study says. The pollutants found in fish disrupt fetal hormones related to metabolism and prompt greater fat storage.
The Food and Drug Administration recommended that pregnant women eat three servings of fish each week.
Researchers found that newborns whose mothers ate fish more than three times a week during pregnancy grew faster in their first years of life, especially when the offspring was female.
The findings were published in the journal JAMA Pediatrics. The study involved 26,184 pregnant women in both the United States and Europe. Researchers observed the growth patterns and weights of the children up to age 6.
But what could happen if a woman eats too much fish during pregnancy?
