Allow gum in schools

One line of research suggests that gum should no longer be treated as contraband in schools. This newest study indicates that chewing gum can lead to better academic performance.

Researchers at the Baylor College of Medicine took 108 eighth-grade math students from a Houston, Texas, charter school and divided them into two groups, following them for 14 weeks. One group chewed gum while doing homework and during test-taking situations. The other group did not chew gum at all.

The results were surprising. The gum-chewing students had a 3 percent increase in their standardized math test scores compared with those who did not chew gum. Also, the students who chewed gum had better final grades compared with the non-chompers.

"Chewing gum is an easy tool students can use for a potential academic edge," says Craig Johnston, Ph.D., the lead researcher and an instructor in nutrition at the Department of Pediatrics at Baylor College of Medicine.

He also reports that teachers anecdotally found that students who chewed gum required fewer breaks, paid better attention and stayed quiet longer than those who did not.

Another study adds to a growing body of evidence centering on chewing gum satiety and cravings. Investigators at Louisiana State University took 115 people who regularly chewed gum and fed them lunch. They measured their cravings before and after lunch. They found that those subjects, who chewed gum three times hourly after lunch, ate fewer high-calorie snacks. The chewers also reported decreased feelings of hunger and cravings for sweet foods.
