Japanese researchers have invented a special kind of electric chopsticks recently.     1    So the chopsticks can help people take in less salt while they are enjoying delicious food.

2    The chopsticks are connected to a small device (装置) worn by the eater. Weak electricity carries sodium ions (钠离子) from food through the chopsticks to the mouth. They’ll create a sense of saltiness in the mouth. As a result, the salty taste increases by 1.5 times. The traditional diet in Japan is salty.      3    That is twice the amount (数量) one should take in according to the World Health Organization (WHO).

Too much salt intake may lead to high blood pressure and some other illnesses.

4    “If we try to avoid taking in too much salt in the usual ways, we need to delete a lot of our favorite food from our food list. Or we have to eat tasteless food,” the researcher said. Now, the electric chopsticks provide us with another way to take in less salt.
