Dark Chocolate Is Antidote to Mid-Day Slump: Study

By    |   Tuesday, 12 May 2015 10:56 AM

Chocolate is not often viewed as a healthy snack, but dark versions can help improve attentiveness and beat mid-day bouts of fatigue, new research shows.

Dark, unsweetened chocolate is known to have cardiac benefits and be a stimulant so North Arizona University researchers wanted to learn if consuming it in the afternoon, when many workers find themselves hitting a slump, would improve performance.

In an experiment, scientists had 122 young adults eat a piece of 60 percent cacao chocolate. They then performed an EEG study to take images of their brain while they performed a cognitive task. Five individuals who did not eat the chocolate were used as controls. The test was also blinded so that the subjects did not know which were consuming the chocolate.

The results for the participants who consumed the 60 percent cacao chocolate showed that the brain was more alert and attentive after consumption. Their blood pressure also increased for a short time.

"A lot of us in the afternoon get a little fuzzy and can't pay attention, particularly students, so we could have a higher cacao content chocolate bar and it would increase attention," said Dr. Larry Stevens, professor of psychological sciences at ASU.

The study appears in the journal NeuroRegulation.
