Foods for Better Concentration
Focusing on the types of foods that you eat may boost performance.
A friend suggested I take ginseng after I complained about
having trouble concentrating on a big project. She said it might help with my

There are apparently many theories on focus-enhancing food and
beverages. Edibles from caffeine to sugar to proteins are touted to help boost
Ubiquitous ads for dietary
supplements add to the mix. Such products are supposed to improve memory,
attention, and brain function.
With all these options offered, what's a person to do on the
eve of an important affair? Can certain victuals help boost alertness for an
exam, a job interview, or a presentation?
Many Food Options
Conversations with various experts reveal that there is both
good and bad news. First, the reality is that there is no one magic food
guaranteed to help people perform their best mentally and physically. The
research on the connection between food and concentration is, for the most
part, either lacking, or inconclusive. Some of the claims attached to certain
foods are exaggerations of the truth, or downright false.
Now, for more the optimistic report: Certain fare may work for
some people for a short-term, and studies are ongoing on the promising benefits
of some nutrients on brain function.
Where does your favorite "food for thought" fit in?
Many everyday folk will swear by the virtues of caffeine and
sugar in picking them up at opportune moments. Their tonic might be a stimulant
such as coffee or tea, or a sweet such as ice cream or pastries, or a food rich
in both such as chocolate, energy drinks such as Red Bull, and sodas.
Caffeine can energize the fatigued, but the benefit is
short-lived, says Noralyn L. Wilson, RD, a spokeswoman for the American
Dietetic Association (ADA). She says individual characteristics determine the
length of the effect and someone's reaction to it.
Some people will feel "up" with the accelerated heart
rate caused by the stimulant, while others may feel jittery and
The discomfort may detract someone from concentrating on a task
at hand. Problems may also come when the effects of caffeine wear off, or if
too much of it is ingested.
"People can overdose on caffeine," says John Allred,
PhD, professor emeritus of nutrition at Ohio State University, noting that
too much of the substance could make a person become unfocused.
The effect of sugar on alertness, on the other hand, appears to
be a bit more complex. It turns out that the brain uses glucose, a type of
sugar, as a primary source of fuel.
In a study of 20 healthy older adults given a sweet drink or
carbohydrates (which metabolize into glucose in the body), participants did
significantly better in memory tests when they were given a placebo drink.
