Children whose moms took high doses of fish oil during their last three months of pregnancy were less likely to develop chronic wheezing problems or asthma by age 5, finds a study that suggests a possible way to help prevent this growing problem.
Asthma cases have been rising in developed countries, while consumption of omega-3 fatty acids like those found in fish has decreased. Some earlier studies suggested that omega-3 deficiency during pregnancy may affect asthma risk in babies, but they were too small to be definitive.
It’s not known why this may be – one theory is that fish oil lowers inflammation, which can tighten airways.
