A recent study from researchers at Kanazawa Medical University
in Japan, proved that traditional Japanese cuisine is key to a good
night's sleep.


Rice has always played an important role within Japanese diets and
indeed culture, but now it is scientifically proven to aid
sleeping. Rice's high GI level, means that the body is able to
quickly break down the carbohydrate and transform it into sugars
and a protein called tryptophan. Research has shown that tryptophan
creates the brain chemical serotonin, which is known to induce
sleep.

Other carbohydrates such as bread and noodles were also included
in the study, but they had little affect on sleep due to their low
GI content.
