in Japan, proved that traditional Japanese cuisine is key to a good
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.
