The work, led by Myles Faith, an associate professor of nutrition at UNC's Gillings School of Global Public Health, adds to the growing body of knowledge that genes play a significant role in children's eating behavior, including the tendency to avoid new foods.
"In some respects, food neophobia, or the aversion to trying new foods, is similar to child temperament or personality," said Faith, whose work appears today in the journal Obesity. "Some children are more genetically susceptible than others to avoid new foods. However, that doesn't mean that they can't change their behaviors and become a little less picky."
The study looked at 66 pairs of twins between ages 4 and 7 years old, and found that genes explain 72 percent of the variation among children in the tendency to avoid new foods, while the rest was influenced by environment. Previous research has shown a similar genetic influence for food neophobia in 8-to-11-year-olds (78 percent) and adults (69 percent), suggesting that the impact of genes on food neophobia is constant across the developmental spectrum.
Faith and his team also examined the relationship between food neophobia and body fat measures in both parent and child. Unexpectedly, the researchers found that if the parent was heavier, the child was heavier only if he or she avoided trying new foods.
"It's unexpected, but the finding certainly invites interesting questions about how food neophobia and temperament potentially shape longer-term eating and influence body weight," said Faith.
On the environmental side, the findings suggest that parents should consider each child's idiosyncrasies, even for siblings in the same household, when thinking about how to increase a child's acceptance of new foods. For example, parents can serve as role models and provide repeated exposure to new foods at home, or show their child how much they enjoy the food being avoided. They might also provide a choice of several new items from which a child could select.
"Each child may respond differently to each approach, and research needs to examine new interventions that take into account children's individuality," said Faith. "But what we do know through this and other emerging science is that this individuality includes genetic uniqueness."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
