Should we play hide-and-go-seek with our children's vegetables?

02.03.2012
A study reveals that vegetables may not have to hide

Pass the peas please! How often do we hear our children say this? According to the Centers for Disease Control and Prevention's Youth Risk Behavior Surveillance System survey of adolescents, only 21% of our children eat the recommended 5 or more fruits and vegetables per day. So not very many children are asking their parents to "pass the peas," and parents are resorting to other methods to get their children to eat their vegetables.

One popular method is hiding vegetables. There are even cookbooks devoted to doing this and new food products promise they contain vegetable servings but don't taste like vegetables! But this ''sneaky'' technique has been controversial, as some dietitians, doctors, and parents have argued that sneaking vegetables into food does not promote increased vegetable consumption because children are unaware they are eating vegetables, and are not likely to continue the practice into adulthood. A study in the March/April 2012 issue of the Journal of Nutrition Education and Behavior found that informing children of the presence of vegetables hidden within snack food may or may not alter taste preference. Acceptability of the vegetable-enriched snack food may depend on the frequency of prior exposure to the vegetable.

Chickpea chocolate chip cookies or chocolate chip cookies? Investigators from Columbia University enrolled 68 elementary and middle school children and asked just that question. In each pair, one sample's label included the food's vegetable (eg, broccoli gingerbread spice cake), and one sample's label did not (eg, gingerbread spice cake). Participants reported whether the samples tasted the same, or whether they preferred one sample. What the children didn't know was that both samples contained the nutritious vegetable. The investigators found that taste preferences did not differ for the labeled versus the unlabeled sample of zucchini chocolate chip bread or broccoli gingerbread spice cake. However, students preferred the unlabeled cookies (ie, chocolate chip cookies) over the vegetable-labeled version (ie, chickpea chocolate chip cookies). The investigators also assessed the frequency of consumption for the three vegetables involved and chickpeas were consumed less frequently (81% had not tried in past year) as compared to zucchini and broccoli.

Ms. Lizzy Pope, MS, RD, the principal investigator of this study states, "The present findings are somewhat unanticipated in that we were expecting students to prefer all three of the ''unlabeled'' samples. These findings are consistent with previous literature on neophobia that suggests that children are less apt to like food with which they are unfamiliar. Since the majority of students had had broccoli and zucchini within the past year (as compared to chickpeas), it appears that there must be some familiarity with a vegetable for the labeling of the vegetable content not to influence taste preference. Considering this then, it is not surprising that the unlabeled version of the chickpea chocolate chip cookies was preferred over the labeled version."

Dr. Randi Wolf, PhD, MPH, co-investigator adds, "Food products labeled with health claims may be perceived as tasting different than those without health claims, even though they are not objectively different. I've even read studies that have shown children like baby carrots better when they are presented in McDonald's packaging. These prior studies suggest the potential power that food labels can have on individuals. Although anecdotal reports suggest that children may not eat food products that they know contain vegetables, little is actually known about how children's taste preferences may be affected when the vegetable content of a snack food item is apparent on the item's label. This study is important in that it may contribute knowledge of the potential effectiveness of a novel way to promote vegetable consumption in children."

Based on what the investigators learned from this study, it seems more important to introduce our children to a variety of vegetables rather than continually hiding them.

The article is "The Influence of Labeling the Vegetable Content of Snack Food on Children's Taste Preferences: A Pilot Study" by Lizzy Pope, MS, RD and Randi L. Wolf, PhD, MPH. It appears in the Journal of Nutrition Education and Behavior, Volume 44, Issue 2 (March/April 2012) published by Elsevier.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
