The Food Battle game helps students better understand the concepts of metabolism and obesity. The game works like this: the player places healthy foods on the board to fight against the unhealthy foods that will attack. At each time interval, a question about nutrition appears. If the player answers the question correctly, an unhealthy food disappears from the game. If not, a healthy food is eliminated, making the game more difficult. The game is won if no unhealthy food reaches the end of the board.
