Chapter 2
Getting Organized
Dear Jen,
Maybe this is a silly question, but are there any special foods I can eat or any
thing else I can do to get smarter?
Sincerely,
Edge Seeker
Dear Edge Seeker,
I doubt that diet can make you “smarter” on a permanent basis, but it is
absolutely true
that how you treat your body will affect how your brain performs. YouVe certainly expe
rienced “brain fog,” or have been unable to think straight after a long night out or a huge
holiday meal. It’s not that hard to adjust your lifestyle to produce the opposite effect.
The basics: your brain likes for your body to be fed a steady diet that includes “good
fats,” antioxidants, and small but regular amounts of quality carbohydrates.
If you are trying
to lose weight, consider putting your diet on hold—if not for the entire
period of your studies, then at least for the period immediately leading up to your actual
exam. Low-carbohydrate diets are especially detrimental to brain function.
A quick internet search will yield suggestions for specific foods that are consistent with
these guidelines: salmon, tuna and other fish, oysters, avocado, olive oil, nuts and seeds,
eggs (especially the yolks), berries, oatmeal, beans, brown rice, fresh coconut, green leafy
vegetables, tomatoes, red cabbage, ginger, rosemary, and even coffee, tea, and choco
late, which are loaded with antioxidants (keep the sugar intake low, though!). Swap out
“white” carbohydrates for whole grain versions, eaten in small but regular portions.
O f course, be aware of any food allergies!
There’s nothing terribly novel about any of this—the above list is similar to the advice
regarding
Mediterranean diets, the maintenance phase of the South Beach diet, anti-ag-
ing diets, the glycemic index, and many other popular, mainstream programs for health
and fitness.
For the record, the most frequently mentioned “brain food” by far is fish; for those who
don’t eat seafood, the “good fats” in flaxseeds, avocado, olive oil, and nuts are often
mentioned as alternatives.
Probably more important than diet, though, is sleep. Various studies list serious conse
quences of sleep deprivation such as: increased stress hormones, poor digestion, a com
promised immune system, inability to put emotional events into the proper perspective,
impairment of ability, and serious attention deficits.
According to a study in the
British Medical Journal, people who have been awake for 17-
19 hours are worse drivers than people with a blood alcohol level of 0.05%. You wouldn’t
take the GMAT drunk, of course. Taking it on too little sleep may be just as bad.
