High in calories and low in nutrients when adolescents share pictures of food online

07.04.2016

A new study from the University of Gothenburg show that adolescents like to present foods that are high in calories but low in nutrients in social media.

Previous studies have found that interactions around food in social media can influence adolescents’ consumption of candy and their willingness to try unfamiliar foods. Research has also shown that food images stimulate areas of the brain that are associated with appetite in children and adolescents.

Analysed Instagram accounts

The new study, published in the scientific journal Appetite, is based on an analysis of over 1000 Instagram accounts belonging to Scandinavian adolescents.

Eighty-five per cent of the accounts shared at least one food image

‘The most common food items were candy, cookies and other baked goods, sweet drinks, chocolate and ice cream. Overall, these types of high-calorie and low-nutrient food items could be found in 68 per cent of the images posted on Instagram,’ says Christopher Holmberg at the Department of Food and Nutrition, and Sport Science and one of the researchers behind the study titled Adolescents’ presentation of food in social media: An explorative study.

Only 22 per cent of the pictures displayed fruits and vegetables

Compared with other food categories, the researchers also found a particularly strong link between high-calorie/low-nutrient foods and positive descriptions and festive environments, such as birthday parties.

Markers of identity

UK studies have found that food brands increase in importance and become important identity markers during adolescence. The researchers from the University of Gothenburg found that Coca Cola, Frappuccino from Starbucks and ice cream from Ben&Jerry’s are well represented in the posted images and therefore something the teenagers helped advertise through their Instagram accounts.

‘This indicates that they are unaware of, or simply accept, this type of product promotion in social media. The fact that the adolescents create and disseminate the advertisements by themselves may imply that this type of informal advertising is more effective than traditional channels,’ associate professor Christina Berg at the Department of Food and Nutrition, and Sport Science.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
