Here are two statements that are true:
1. Too much salt is bad for you
2. Salt makes things taste delicious.
These two facts can raise a tricky question for us—do we want to be healthy or do we want food that tastes good? A developing technology in Japan could help put an end to the conflict created by our enjoyment of salt. A restaurant in Tokyo ran a 2-day trial featuring a menu with no salt and an “electro fork,” that mimics the taste of salt by zapping diners tongues with electrical current. This actually isn’t the first time engineers endeavored to get us to eat healthier with a jolt of electricity. In 2013 an engineer from Singapore developed digital taste interface in the shape of lollipop that could make people believe they were eating something salty, sour or bitter.
