Interesting Food - Chewing Gum

According to research from Cardiff University in Wales, chewing gum is good for the brain.

(Chewing boosts thinking and alertness and reaction times among chewers are up to 10 per cent faster.

Volunteers carried out tasks while chewing and not chewing gum as their brains were scanned to see which areas were active. During the 30-minute tests participants pressed a button with their right or left thumb in response to the direction of an arrow on a screen. Men and women who were not chewing took 545 milliseconds to react, compared with 493 milliseconds among the chewers. The brain regions most active during chewing were those involved with movement and attention.

The act of chewing leads to the production of higher levels of insulin, which stimulates areas of the brain.

That's something to chew on, and it might explain why I used to chew my pen at school.  I was improving my ability to concentrate.)
