Between 10 and 30% of preterm births are caused by uterine infections with a type of bacteria named F. nucleatum, commonly found in the mouth. When reaching the placenta, the bacteria causes inflammation, which endangers the pregnancy.
The scientists discovered that omega-3 fatty acids, common in fish oil, were able to reduce the inflammation and bacterial growth in lab animals. Moreover, supplements with these fatty acids reduced miscarriages in pregnant mice.
To prove the same benefits will be available to humans, the omega-3 acids should be tested in future clinical trials.
