If you are a parent, or know a parent, you have had someone claim that if their kid eats sugar they get 'hyperactive' - that may happen, but only because a child has been told they get hyperactive and act that way, the same way if you tell a child rum cake has rum they may act drunk.

A new study sought to analyze the chewing nature of four types of gum bases and along the way determine bubbling capacity also. Gums are generally oils, resins, and elastomers generally held in pleasant form by the gum base. 

So gum base is important to manufacturers. Chewing gum is a $25 billion per year business, 1,740,000,000,000 sticks. If humans chew each stick for 10 minutes, that is over 33,000,000 years we spend at it - annually.
