Fish Intake In Pregnancy And Child Growth, A Pooled Analysis Of 15 European And US Birth Cohorts, JAMA Pediatrics, 15 February 2016
Design, Setting, and Participants: Multicenter, population-based birth cohort study of singleton deliveries from 1996 to 2011 in Belgium, France, Greece, Ireland, Italy, the Netherlands, Norway, Poland, Portugal, Spain, and Massachusetts. A total of 26 184 pregnant women and their children were followed up at 2-year intervals until the age of 6 years.
Results: This multicenter, population-based birth cohort study included the 26 184 pregnant women and their children. The median fish intake during pregnancy ranged from 0.5 times/week in Belgium to 4.45 times/week in Spain. Women who ate fish more than 3 times/week during pregnancy gave birth to offspring with higher body mass index values from infancy through middle childhood compared with women with lower fish intake (3 times/week or less). High fish intake during pregnancy (>3 times/week) was associated with increased risk of rapid infant growth, with an adjusted odds ratio (aOR) of 1.22 (95% CI, 1.05-1.42) and increased risk of offspring overweight/obesity at 4 years (aOR, 1.14 [95% CI, 0.99-1.32]) and 6 years (aOR, 1.22 [95% CI, 1.01-1.47]) compared with an intake of once per week or less. Interaction analysis showed that the effect of high fish intake during pregnancy on rapid infant growth was greater among girls (aOR, 1.31 [95% CI, 1.08-1.59]) than among boys (aOR, 1.11 [95% CI, 0.92-1.34]; P = .02 for interaction).
Conclusions: High maternal fish intake during pregnancy was associated with increased risk of rapid growth in infancy and childhood obesity. Our findings are in line with the fish intake limit proposed by the US Food and Drug Administration and Environmental Protection Agency.
Why fish? The Physicians Committee for Responsible Medicine says, “researchers suspect chemical pollutants found in fish may alter fat metabolism and thus contribute to weight gain.”
I’ve been saying this for years … chemicals in our food act as endocrine disruptors (EDs). And seafood has become some of the dirtiest food we eat. Animal food in general contains higher levels of metabolism-disrupting chemicals owing to bioaccumulation. Overweight is just one health problem associated with EDs. The ailment list is lengthy … diabetes, fertility problems, birth defects, neurological disorders, and on.
Do pregnant women know they shouldn’t be eating seafood? Is that common knowledge?
