benefits to offspring of fish consumption

by women of childbearing age,

particularly pregnant women

and nursing mothers, and the

neurodevelopmental risks of

not consuming fish

to offspring of such women;

In contrast to the cited conclusion of 2006, VKM concludes in this report that there is no reason for specific dietary limitations on fatty fish consumption

for pregnant women.
