Chewing Gum Improves Memory

Tuesday, 26 June 2007 12:00 AM

Lousy memory? A university study shows that you can improve your memory simply by chewing gum, says renowned health expert Dr. Susan Lark.

The study took 75 adults and divided them into three groups, then administered a 20-minute memory test. The first group chewed gum during the test, the second group simulated chewing with nothing in their mouths, while the third group took the test without chewing at all.

The gum-chewers scored 24 percent higher on immediate word recall, and 36 percent higher on delayed word recall. The researchers aren't sure, however, how the chewing gum does its trick.

Some believe chewing gum raises the activity level in an area of the brain called the hippocampus, which is an area thought to be important for memory. MRI studies do, in fact, show that the hippocampus lights up when people chew.

Others have a simpler theory – past studies have demonstrated that chewing gum makes the heart beat faster, which increases blood flow and delivers more oxygen to the brain.

What kind of gum sharpens memory the best? Apparently any kind will do, but perhaps it's prudent to stay away from gum sweetened with sugar, or with questionable chemicals. Some experts believe that xylitol-sweetened gum is best, since it doesn't raise your blood sugar, and may even be good for your teeth and gums.
