URTIs include the common cold and sinus infections, which can lead to lower respiratory problems, such as asthma or pneumonia. Even though the majority of URTIs are uncomplicated colds, identifying ways to prevent their occurrence is important because colds are the most common reason for school and work absences. Eating nutritious foods, especially fruits and vegetables, improves immunity but hadn't previously been associated with reducing the risk of URTIs in pregnant women.
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 amount. Neither fruit nor vegetable intake alone was found to be associated with the five-month risk of URTI. The patterns observed for total fruit and vegetable intake and either fruit or vegetable intake alone in relation to the three-month risk of URTI were consistent with those when assessing the five-month risk of URTI. Women in the highest quartile of fruit and vegetable intake had a stronger reduced three-month risk than the five-month risk of URTI. Moreover, there was a significant decreasing linear trend for the three-month risk of URTI with consumption of fruits and vegetables.
Pregnant women have been recommended to consume at least five servings of fruits and vegetables per day. This study showed that intake of higher levels, 6.71 servings per day, was associated with a moderate risk reduction for URTI.
"Pregnant women may require more fruits and vegetables than usual because of the extra demands on the body," said senior author Martha M. Werler, M.P.H., Sc.D., professor at Slone Epidemiology Center at Boston University.
This study was supported by the National Institute of Dental and Craniofacial Research. The Institute had no role in the design and conduct of the study, the collection, management, analysis and interpretation of the data, or the preparation, review and approval of the manuscript.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
