Children choose healthy snack options after playing a simple video game.
Children can now be trained to choose healthy food by making them play a simple game. Children who played a seven-minute game devised by University of Exeter psychologists made healthier choices when asked to pick foods afterwards.
‘Age did not matter in determining whether the game served its purpose, meaning children as young as four can benefit from playing this game.’
The game involves reacting to images of healthy food by pressing a button, and doing nothing if unhealthy foods are shown."The sight of foods like chocolate can activate reward centres in the brain at the same time as reducing activity in self-control areas," said lead researcher Lucy Porter.
"Our training encourages people to make a new association - when they see unhealthy food, they stop. Many health promotion schemes rely on education and willpower and require a lot of time, staff and money, but our game potentially sidesteps these issues by creating a free, easy tool for families to use at home," she said, noting, "The research is at an early stage and we need to investigate whether our game can shift dietary habits in the long-term, but we think it could make a useful contribution."
The researchers ran two experiments and in total more than 200 schoolchildren aged 4-11 were shown images of healthy and unhealthy foods. Alongside each image was a cartoon face - happy for healthy food, sad for unhealthy food. Children had to hit the spacebar when they saw a happy face, and do nothing if they saw a sad face - they were not told that the game had anything to do with healthy or unhealthy food.
Afterwards, they played a shopping game where they had to choose a limited number of food items in one minute. "We didn't see a total turnaround in favour of choosing healthy options, but these increased from about 30% of foods chosen to over 50% in children who did the brain training," said Porter.

Similar research by senior author Natalia Lawrence already led to the creation of an app, which helps adults avoid unhealthy foods and lose weight. "It's encouraging to see that this simple computer game has the potential to improve food choices in young children as well as in adults" she said.

Porter added: "This easy game does all the hard work for you. It's not about learning anything consciously; it's about working with automatic responses. She acknowledges that some people might feel uneasy about this, but she explains: "Playing this game is optional - unlike the constant stream of advertising designed to brainwash children.
