December 29, 2016 — Women who took fish oil during the last three months of pregnancy significantly lowered the risk that their children would develop asthma, a study in Denmark has found.
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.
