Of the 8,729 women who participated in the study, only 1.9% of those who are fish at least once a week gave birth prematurely. This compares to 7.1% of the women who never ate fish


Furthermore, birth weight and the length of gestation also rose with increasing fish consumption.


The study’s authors, Sjúr ur Fró i Olsen, associate professor of the Maternal Nutrition Group, Danish Epidemiology Science Centre, and Professor Niels Jørgen Secher from the Perinatal Epidemiology Research Unit of Skejby University Hospital, report that this adds further evidence that fish oil can prove beneficial to pregnant women. These benefits are supposed to derive from the omega-3 fatty acids found in fish.


The study was funded by the Novo Nordisk Forskningsfond, Aage-Louis Hansens Fond, the Danish National Research Foundation, the March of Dimes Birth Defects Foundation, the Danish Health Research Foundation, and Egmont Fonden.
