Chewing gum does not make you smarter

Some early research found that gum chewing improved performance on memory tests,perhaps by boosting blood flow to the brain and stimulating a part of the brain where information is processed.But more recent studies have failed to find any brain benefit-or have noted that gum sometimes worsens performance.Another recent study in appetite found that gum improved performance on certain cognitive tests,but only when it was chewed before,not during the tests.The benefit lasting just 15-20 minutes.According to the researchers Gum does not help thinking-and possibly even impairs it-during a task because of "interferance due to a sharing of metabolic resources by cognitive and masticatory processes" In other word some people cannot think and chew gum at the same time.
