What you eat determines the way you think

KNIGHT RIDDER NEWSPAPERS
You're determined to lose those 10 pounds you gained. You start a diet with a strict regimen that forbids many of your favorite foods.
It seems simple enough. But the downside is that you're thinking about food all the time. What's for dinner? Pasta is out. What's for a mid-afternoon snack? No Snickers bars. Where did you pack that apple? You just had lunch and you're still hungry.
That brings us to the real problem. You're not thinking about much else but food.
Allure magazine says researchers at Flinders University in Australia studied 64 women, half of whom were said to be dieting. They administered cognitive tests and found that the dieters had difficulty performing simultaneous tasks and recalling sequences.
Researchers concluded that the obsession with food and body shape hindered mental efficiency in other areas.
The lesson here: Eat hearty when you're about to take oral exams or deliver an important presentation.
