A study by the Ryerson University in Toronto showed that playing Angry Birds made players consume 50 fewer calories at mealtime than at a meal having not played it prior. The reason was that people felt happier after playing the game, which made them consume less.

It has been confirmed that the Pigs in the game have no desire to harm the birds.

During development, Rovio got the idea to make the enemies pigs because of the Swine Flu epidemic. The pig's sickly green color is a reference to this.

Collectively, more than 200,000 years have been spent playing Angry Birds; Roughly the same amount of time that modern humans have existed.
