In a discovery that will give nutritionists the shivers,a Japanese scientist has discovered that consumingice cream for breakfast improves a person's alertness and mental performance.


Yoshihiko Koga, a professor at Tokyo's Kyorin University, has carried out a series of clinical trialsin which test subjects were required to eat ice cream immediately after waking up.


They were then put through a series of mental exercises on a computer.


Compared to a group that had not eaten ice cream, Prof Koga's subjects exhibited fasterreaction times and better information-processing capabilities, the Excite News web sitereported.

据Excite News网站报道,古贺佳彦发现,与没有摄入冰淇淋的一组相比,摄入冰淇淋的测试者反应速度更快,且处理信息的能力更强。

Monitoring of the subjects' brain activity revealed an increase in high-frequency alpha waves,which are linked to elevated levels of alertness and reduced mental irritation.


To examine the possibility that the test subjects' reactions were simply the result of the brainbeing shocked into higher levels of alertness by the low temperature of the ice cream, ProfKoga repeated the experiment with cold water instead of ice cream.


Test subjects who drank cold water did display a degree of increased alertness and mentalcapacity, although the levels were markedly lower than among subjects who started the daywith ice cream.


Prof Koga is a specialist in psychophysiology, with his studies including looking into linksbetween certain types of food and reduced stress.


Another area of study is the connection between different foods and their impact on the ageingprocess.


Prof Koga is continuing his research and has yet to determine a firm connection between themental boost delivered by ice cream and a specific ingredient, while another explanationmay lie in the sense that ice cream is a treat that triggers positive emotions and added energy.


British nutritionists have reacted with some skepticism to Dr Koga's findings.


"A possible explanation (for increased alertness)... is the simple presence of consumingbreakfast vs. not consuming breakfast," said Katie Barfoot, a Nutritional Psychology DoctoralResearcher at Reading University.


"Our brain needs glucose to function, and a high glucose meal will aid mental capacityconsiderably compared to a fasted brain.


"This, however, does not condone eating dessert for breakfast. A study which explores theinteraction between consumption of low and high GI foods, whilst including a fasted group,would establish a better understanding of this increased mental capacity."


There has already been some scientific research into why ice cream may have a positive mentaleffect on those who eat it.


In 2005, neuroscientists at the Institute of Psychiatry in London scanned the brains of testsubjects as they ate vanilla ice cream and saw immediate results.


The study found that eating ice cream activated the same "pleasure spots" of the brain that arelit up by winning money, or listening to a favourite piece of music.


"This is the first time that we've been able to show that ice cream makes you happy," Unileverspokesman Don Darling said at the time.


"Just one spoonful lights up the happy zones of the brain in clinical trials."


It's not the first time a study has suggested a high-calorie "dessert" could be better eaten inthe morning, either - a 2012 study found that eating chocolate cake for breakfast could help youlose weight.
