Because if they have candy like everyday and not as a special treat, they will be acustomed to having it all the time which will later lead to obesity and poor health when they obtain such unhealthy habits.Why should teenagers NOT be encouraged to have chocolate bars on a regular basis?
I can think of no good reason. Chocolate has a bad reputation but is not all that bad when eaten in moderation.
