Summary

This study tests whether giving pregnant women fish oil supplements can prevent asthma, eczema, and allergies in their children. 800 mothers took fish oil or a placebo from week 24 of pregnancy until one week after birth. The children are then followed for several years to see if they develop these conditions.

What this could lead to
