Japanese researchers have developed computerized chopsticks that enhance salty tastes, potentially helping those who need to reduce sodium in their diets.
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, said Miyashita.
“As a result, the salty taste enhances 1.5 times,” he said.

The taste-enhancing chopsticks may have particular relevance in Japan, where the traditional diet favors salty tastes. The average Japanese adult consumes about 10 grams of salt per day, double the amount recommended by the World Health Organization.
Excess sodium intake is related to increased incidence of high blood pressure, strokes and other ailments.

“To prevent these diseases, we need to reduce the amount of salt we take,” said Kirin researcher Ai Sato.
“If we try to avoid taking less salt in a conventional way, we would need to endure the pain of cutting our favorite food from our diet, or endure eating bland food.”
Miyashita and Kirin are refining their chopsticks prototype and hope to commercialize them as early as next year.
