In a discovery that will give nutritionists the shivers, a Japanese scientist has discovered that consuming ice 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 trials in 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 faster reaction times and better information-processing capabilities, the Excite News web site reported.
There has already been some scientific research into why ice cream may have a positive mental effect on those who eat it.
In 2005, neuroscientists at the Institute of Psychiatry in London scanned the brains of test subjects 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 are lit up by winning money, or listening to a favourite piece of music.
