Japanese scientists have invented a special spoon that adds a salty taste to regular food

This unique invention will help reduce the risk of strokes and blood pressure surges in those who suffer from excess salt intake. And while the problem is particularly acute in Japan, where diets are traditionally high in salt, this spoon could be useful for people around the world.

The spoon recently went on sale for 19,800 yen and is already available in Japanese stores. The developers plan to sell a million copies worldwide in five years. It is the first technology to be commercialized since winning the Ig Nobel Prize last year.
