Crucial issue was whether or not the girl ate fish or not. This contrasts with present recommendation warning pregnant girls to not eat sure varieties of fish which have comparatively excessive ranges of mercury.

Though a number of research have addressed this challenge, this analysis targeted on two contrasting research of populations with mercury ranges measured throughout being pregnant the place kids have been monitored at frequent intervals throughout childhood.

“The Advantages of Fish Consumption: Findings for Prenatal Mercury Publicity and Outcomes for Kids within the ALSPAC Prenatal Cohort” by Caroline Taylor et al. Neurotoxicology


Abstract

The Advantages of Fish Consumption: Outcomes for Prenatal Mercury Publicity and Baby Outcomes from the ALSPAC Prenatal Cohort

Well being recommendation to pregnant girls concerning the consumption of meals containing mercury has led to anxiousness, with the resultant avoidance of fish consumption throughout being pregnant. Nonetheless, seafood incorporates many vitamins important for the expansion and improvement of youngsters.

Longitudinal research within the Seychelles, the place fish is a significant part of the food plan, haven’t demonstrated hostile cognitive results in kids with elevated maternal mercury ranges. Is it the identical in a extra developed nation (the UK) the place fish is eaten much less incessantly?

We overview publications utilizing knowledge collected by the Avon Longitudinal Research of Dad and mom and Kids (ALSPAC) to handle this matter. Whole mercury ranges have been measured in complete maternal blood and umbilical twine tissue. The offspring have been adopted all through childhood, notably their cognitive improvement. No hostile associations have been famous.

Considerably helpful associations with prenatal mercury ranges have been demonstrated for complete and efficiency IQ, mathematical/scientific reasoning, and delivery weight in fish-consuming moms in comparison with non-fish-consuming moms.

These helpful outcomes are just like these seen within the Seychelles the place fish consumption is excessive and prenatal Hg ranges are 10 occasions greater than US ranges. Authorities suggestions must be reviewed to emphasise the helpful worth of fish consumption throughout being pregnant.
