Is the coffee too bitter? Add pinch salt

Want to drink coffee but too bitter, add sugar and afraid of high calories? Maybe try adding a pinch of salt. VinePair, a well-known beverage information website, said that adding salt can not only reduce the bitterness, but also make the coffee more mellow. This "secret recipe" comes from a study published in the British journal Nature. The study says that sodium ions in salt can inhibit bitterness and increase aroma.
In fact, nothing can sweeten the coffee. A study from the University of Oxford shows that mugs of different shapes affect the taste of coffee, higher mugs make coffee sweeter, and coffee in "thin" cups tastes more bitter than "fat" cups. The reason why people feel that coffee in short cups is more bitter is that they subconsciously think that tall cups will be filled with more milk or water, and the difference between "fat" and "thin" cups is the same, the researchers reported in Food quality and preference.
