The Japanese beverage and food company Kirin is about to release a line of bowls and spoons (developed alongside Meiji University) that uses a weak electrical current to make food taste saltier without actually increasing the salt content. They’ll hit the commercial market by 2023, and work by making more sodium ions hit taste buds. Too much salt can lead to high blood pressure, and Japanese men eat more than twice the recommended amount of salt per day.
