Mothers’ omega-3 reduces asthma in offspring
Childhood asthma in the United States is increasing and at historically high levels. Doctors believe one factor is low levels of omega-3s in the Western diets consumed by mothers during pregnancy. In this study, 663 women in the 24th week of pregnancy began taking 2,400 mg of omega-3 fish oil per day, or a placebo, through birth.

Doctors followed the children for five years and found kids born to moms in the omega-3 group were 31 percent less likely to have developed asthma compared to kids whose moms had taken the placebo. Kids of the omega-3 moms were also 28 percent less likely to develop persistent wheeze, and were less likely to have respiratory infections. Results were greatest for children of mothers who began the study with the lowest levels of EPA and DHA. They were 54 percent less likely to have developed asthma compared to kids of moms in the placebo group.
