A Danish study’s results suggests pregnant women that take a fish oil supplement during the final 3 months of pregnancy may reduce their baby’s risk of developing asthma or persistent wheezing.
The study involved 736 pregnant women, in their third trimester. Half the women took a placebo containing olive oil and the other group was given 2.4 grams of fish oil. The women took the supplements until one week after birth.
Among children whose mothers took fish-oil capsules, 16.9 percent had asthma by age 3, compared with 23.7 percent whose mothers were given placebos. The difference, nearly 7 percentage points, translates to a risk reduction of about 31 percent.
In the study, the researchers noted that they are not ready to recommend that pregnant women routinely take fish oil. Although the results of the study were positive, several experts have noted that more research needs to be done before higher doses of fish oil supplements are recommended over eating more fish.
Researchers found no adverse effects in the mothers or babies, the doses were high, 2.4 grams per day is 15 to 20 times what most Americans consume from foods.
