Genes may be reason some kids are picky about food

21.03.2013
Parents may plead, cajole or entice their children to try new foods, but some kids just won't budge. Now, new research from the University of North Carolina at Chapel Hill reveals that the reason these kids fear new foods has less to do with what's on their plate and more to do with their genes.

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."

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
