Scientists from the University of Copenhagen found that women taking fish oil supplements during pregnancy were associated with an increased risk of metabolic syndrome and overweight in their children up to the age of ten. results published In the American Journal of Clinical Nutrition (AJCN).
736 pregnant women participated in the study. They were randomly assigned to an intervention group or a control group at 24 weeks of gestation. Participants in the intervention group were instructed to take 2.4 grams of long-chain polyunsaturated fatty acids (n-3 LCPUFA) from fish oil daily as a dietary supplement. Subjects in the control group received a placebo of similar dosage and appearance.
It was noted that participants stopped taking the supplements one week after birth. After the experimental phase was completed, the observation phase of the subjects (mothers and children) began, which lasted approximately ten years. To evaluate the effects of fish oil on children’s health, researchers collected health information from 688 boys and girls, 341 in the intervention group and 347 in the control group.
It turned out that ten-year-old children in the intervention group had a significantly higher body mass index than their peers whose mothers represented the control group. They also had a higher risk of being overweight. A body composition study found that children of women who consumed fish oil during pregnancy had significantly higher muscle and fat mass than children in the control group.
It was also found that taking fish oil was associated with a higher risk of developing metabolic syndrome, a metabolic disorder associated with obesity, diabetes and heart disease in children.
