Japanese scientists made smart chopsticks.

These chopsticks are connected to a special device on a person’s wrist. The device has a small computer to make the chopsticks move while a person eats. Then, sodium ions in the food start to move, and they make the food taste more salty.

Scientists tested the chopsticks on people who were on a diet, and they couldn’t eat much sodium. These people were happy, as the food tasted saltier and better. They didn’t need to eat food with no taste.

Japanese people eat a lot of salt in their diet, which is bad for a healthy lifestyle. Smart chopsticks could help people who like salty food, but they want to be healthy.

Difficult words: chopsticks (a pair of sticks which people in Asia use to eat food), sodium ion (a chemical which is important for some living things), sodium (a soft silver-white chemical which is a part of salt).
