BUSM researchers studied more than 1,000 pregnant women and found those who ate the most fruits and vegetables were 26 percent less likely to have URTI relative to those who ate the least.

Pregnant women have been recommended to consume at least five servings of fruits and vegetables per day, said a BUSM release.

This study showed that intake of higher levels, 6.71 servings per day, was associated with a moderate risk reduction for URTI.

The study appeared online in the journal Public Health Nutrition.
