What a revealing chant: “Trick or Treat?”. But is Halloween candy really a treat? Lately I’ve been thinking a lot about the psychology tied up in junk food. How many times have you heard yourself justify an excessively sugary/fatty food by saying, “I deserve a little treat.” Why is it that we consider something so unhealthy as a reward for our good behaviour or even more strange, for our good eating habits? It’s all a trick, when you think about it.
