I have a problem with chewing WAY to much gum. Like seriously, too much. At one point, I ate a pack a day by myself. It became such a habit that 5 minutes after putting a piece of gum in my mouth I would unconsciously reach for another. One of the main ingredients in sugarless gum (most all of it you find in stores; my personal favorite is Extra Peppermint) is Aspartame. I am aware of the dangers of aspartame, but still continue to chew gum none the less. So my news years resolution: STOP CHEWING GUM. I know that this will positively effect my body, and keep my brain from ongoing neurological damage. This article points out some of how aspartame affects the body and brain, backing it up with scientific data. Enjoy!
