The title - Chew on this: It's for your health

Last February, in a study published in the journal Archives of Surgery, California researchers found that, among 34 people who received colon surgery, those who chewed gum during recovery were able to leave the hospital sooner. Abdominal surgery can stop or slow the workings of the intestines, and people can't usually eat right away. Chewing gum instead may, like chewing food, stimulate the release of gut-healing hormones.
There are mental benefits too, Wrigley's Leveille says. He cites a Chinese study of nine people that found chewing gum boosted blood flow to the brain by as much as 40%. And a Britain-based study on 75 people, published in the journal Appetite in 2002, found that chewers did better in a word memory test.
From a list of 15 words, gum chewers recalled eight or nine words right away and seven words 25 minutes later. Nonchewers and people who pretended to chew remembered six or seven words at first and five words later. Although the scientists don't know the reason, they hypothesize that the act of chewing increases a person's heart rate and delivers more oxygen to the brain.
