Pro: Chewing gum can improve memory, say UK psychologists. They found that people who chewed throughout tests of both long-term and short-term memory produced significantly better scores than people who did not.
One third of the 75 adults tested chewed gum during the 20-minute battery of memory and attention tests. One third mimicked chewing movements, and the remainder did not chew.
The gum-chewers' scores were 24 per cent higher than the controls' on tests of immediate word recall, and 36 per cent higher on tests of delayed word recall. They were also more accurate on tests of spatial working memory.
A recent study shows that chewing gum actually improves your memory and intelligence. That's right--it makes you sharper! Researchers from the University of Northumbria in Great Britian tested 75 people, giving some gum and some none, while others chomped on air as if they had gum. The result? Those who chewed gum (the real stuff, not air bubbles) did better on tests and memorizing things than those who didn't. What's going on? One of two things: 1) The movement you make when chewing gum makes your body think it's going to get food, which then causes it to release insulin to the brain and help it learn; or 2) chewing gum increases the heart rate, which sends more oxygen to the brain. So next time you're cramming for that big chemistry test
