When You Blew by Breakfast...
No one's claiming that prepackaged cereal bars—even fiber- and protein-packed ones—are the healthiest or most slimming snack choice (most contain more sugar than your dietician would recommend). But a study at the U.K.'s Cardiff University found that this ultra-convenient snack has its advantages if the alternative is an empty stomach. When women ate a cereal bar as a midmorning snack, especially if they hadn't eaten breakfast, they became much more alert and less anxious than those who didn't snack. Moreover, they showed an improved ability to remember words they had just learned—a likely result of the protein and a well-timed (and, er, significant) glucose rise.
