Cocoa & caffeine are good choices for students
and anyone else who needs to improve sustained attention
Newswise, March 13, 2017 — Deep
down, we always knew it, but science is proving that cocoa and caffeine are
indeed the best marriage ever. Clarkson University researcher Ali Boolani recently
completed a study that explores the powers of these two dark delights.
The assistant professor of physical
therapy and physician assistant studies teamed up with colleagues at the
University of Georgia to examine the “acute effects of brewed cocoa consumption
on attention, motivation to perform cognitive work and feelings of anxiety,
energy and fatigue.”
In a nearly year-long double-blind
study, some lucky test subjects drank brewed cocoa, cocoa with caffeine,
caffeine without cocoa, and a placebo with neither caffeine nor cocoa. Then
they were asked to do tests to evaluate both cognitive tasks and mood.
“It was a really fun study,” Boolani
says. “Cocoa increases cerebral blood flow, which increases cognition and
attention. Caffeine alone can increase anxiety. This particular project found
that cocoa lessens caffeine's anxiety-producing effects -- a good reason to
drink mocha lattes!”
Before you envy the test subjects
too much, bear in mind they had to work for the warm drinks.
For example, they were asked to
watch as letters flashed across a screen and note when an “X” appeared after an
“A.” They also had to point out when odd numbers appeared sequentially, and
they were required to do subtraction.
“The results of the tests are
definitely promising and show that cocoa and caffeine are good choices for
students and anyone else who needs to improve sustained attention,” says
Boolani.
Here's the best news for the rest of
us: The Hershey Company sponsored the research, so customers logically could
see some new or enhanced products on the market as a result.
Boolani and his colleagues -- Jacob
B. Lindheimer (War Related Illness and Injury Study Center - VA New Jersey
Health Care System), Bryan D. Loy (Oregon Health & Science University),
Stephen Crozier (The Hershey Company), and Patrick J. O’Connor (University of
Georgia) -- have published a paper about the
results of their study in the journal BMC Nutrition.
“I'll be doing some related and
follow-up studies at Clarkson to look at differences in natural vs. synthetic
caffeine, and other cocoa studies” Boolani adds. “I'm excited about them.”
Heads up. He'll be looking for more
test subjects.
