According to a study, intellectual activities make people eat more than when just resting. This has shed new light on brain food. This finding might also help explain the obesity epidemic of a society in which people often sit.
Researchers split 14 university student volunteers into three groups for a 45-minute session of either relaxing in a sitting position, reading and summarizing a text, or completing a series of memory, attention, and alert tests on the computer. After the sessions, the participants were invited to eat as much as they pleased.
Though the study involved a very small number of participants, the results were stark. The students who had done the computer tests downed 253 more calories or 29.4 percent more than the couch potatoes. Those who had summarized a text consumed 203 more calories than the resting group.
Blood samples taken before, during, and after revealed that intellectual work causes much bigger fluctuations in glucose(葡萄糖) levels than rest periods, perhaps owing to the stress of thinking.
The researchers figure the body reacts to these fluctuations by demanding food to restore glucose--the brain’s fuel. Glucose is converted by the body from carbohydrates (碳水化合物) and is supplied to the brain via the bloodstream. The brain cannot make glucose and so needs a constant supply. Brain cells need twice as much energy as other cells in the body.
Without exercise to balance the added intake, however, such "brain food" is probably not smart. Various studies in animals have shown that consuming fewer calories overall leads to sharper brains and longer life, and most researchers agree that the findings apply, in general, to humans.
And, of course, eating more can make you fat.
"Caloric overcompensation following intellectual work, combined with the fact that we are less physically active when doing intellectual tasks, could contribute to the obesity epidemic currently observed in industrialized countries," said lead researcher Jean-Philippe Chaput at Laval University in Quebec City, Canada. "This is a factor that should not be ignored, considering that more and more people hold jobs of an intellectual nature," the researcher concluded. [br] According to the passage, eating less may make people ______.
