  • Researchers in Japan say they will begin selling new devices that will help people reduce how much sodium, or salt, they use to improve the taste of their food.
    • 2
  • The developers are from Japan's Meiji University and drink company Kirin based in Tokyo.
    • 3
  • One new device is an electric spoon.
    • 4
  • It uses a small computer worn on a person's arm to send electrical signals to activate sodium atoms.
    • 5
  • The developers say the signals increase the food's salty taste.
    • 6
  • The Electric Salt Spoon will sell in Japan for around $120 beginning in June.
    • 7
  • Meiji University professor Homei Miyashita developed the spoon and a similar device, electric chopsticks.
    • 8
  • The chopsticks will likely go on sale next year.
    • 9
  • The recent announcement marks the first time the technology has been used in a product for sale to the public.
    • 10
  • Last year, the effort gained a different sort of attention.
    • 11
  • It won the 2023 Ig Nobel Prize in nutrition. Organizers describe the prize as recognizing research that makes "people LAUGH, then THINK."
    • 12
  • The devices both use a weak electrical current to send the sodium ions from food, through the chopsticks or spoon, to the mouth where they create a sense of saltiness, said Miyashita.
    • 13
  • "As a result, the salty taste enhances one and a half times," he said.
    • 14
  • Miyashita and his laboratory have explored ways that technology can interact with and create human sensory experiences.
    • 15
  • He has also developed a lickable TV screen that can recreate the taste of food.
    • 16
  • The beer producer Kirin is turning to healthcare products to expand its traditional business.
    • 17
  • A company spokesperson said the technology might be especially useful for Japanese people, whose traditional diet favors salty foods.
    • 18
  • The average adult in Japan consumes about 10 grams of salt per day.
    • 19
  • The World Health Organization recommends half that amount.
    • 20
  • Eating foods with too much sodium can increase the chances of having high blood pressure, strokes and other health problems.
    • 21
  • "To prevent these diseases, we need to reduce the amount of salt we take," said Kirin researcher Ai Sato.
    • 22
  • Sato said it is hard to cut salt in the usual way because it would mean "eating bland food."
