Not enough salt? These chopsticks can help

Japanese researchers have developed computerised chopsticks that enhance salty tastes, potentially helping those who need to reduce sodium in their diets.

The chopsticks are co-developed by Meiji University professor Homei Miyashita and beverage maker Kirin Holdings Co. They enhance taste using electrical stimulation and a mini-computer worn on a wristband.

The device uses a weak electrical current to transmit sodium ions from food, through the chopsticks, to the mouth where they create a sense of saltiness. The salty taste is enhanced 1.5 times.

The average Japanese adult consumes about 10 grams of salt per day, double the amount recommended by the World Health Organisation. Excess sodium intake is related to increased incidence of high blood pressure, stroke and other ailments. The makers said the aim was to reduce the amount of salt Japanese consume.

Miyashita and Kirin are refining their chopsticks prototype and hope to commercialise them as early as next year.
