B
Do you want to eat more healthily? Try Food Trainer!
It's an app from the UK. It helps people eat less unhealthy food by playing a game.
In the free game, healthy food always comes in green circles（圆圈） and unhealthy food always comes in red circles. If a user clicks（点击） on a thing in the green circle, he or she will get a point. But clicking on a thing in the red circle will make the user lose a point.
Does this easy game work well? The makers of the app make a study. They work with some scientists from Finland. Together they ask more than 1,200 volunteers（志愿者） to play the game once a day. After a month, the volunteers find changes in their diet. Most of them say they ate unhealthy food three to four times a week in the past. But now, they
reduce this to once a week.
Why does the app work so well? It's because it uses brain training techniques（大脑训练技术）. The game makes users' brains stop when they see junk food. This helps users say no to unhealthy food in their daily lives.
