Donuts and Coffee good for the brain? 'Doh


Donut lovers rejoice! The food your brain needs to make it through a tough day? Donuts and coffee. Take that, Martha Stewart.

Gary L.Wenk, author of "Your Brain on Food" writes in Psychology Today that the brain needs a constant supply of sugar to produce energy. "Your neurons can only tolerate a total deprivation of sugar for a few minutes before they begin to die."

One key ingredient to keeping your brain alert and ready to learn is lecithin, which just happens to be found in chocolate, in donuts and in cupcakes (Ugh, not another reason to go to Georgetown Cupcake, please).

Wenk goes on to explain another trick to stave off the sleepiness: caffeine, which stops the chemical Adenosine from turning brain neurons off.

So, there you have it: chocolate donuts and coffee makes a brain happy. Too bad Wenk has to ruin the fun by reminding us, "what our brain wants is not always good for our bodies."

(It feels like a job-well-done kind of day when I have two reasons to use Homer Simpson photos on my blog.)
