What can we taste with our tongue?
Sweet, salty, bitter, sour
Sweet, salty, bitter, sour, spicy
Sweet, salty, bitter, sour, umami
Our tongue conveys only 5 tastes: sweet, salty, bitter, sour, and umami. The sense impression that people speak of when they speak of taste is actually an interplay of sense of taste, sense of smell, sense of touch, temperature, and sense of pain. The receptor cells that perceive the 5 tastes on the tongue are arranged in taste buds in mammals. A taste bud contains between 50 and 150 such receptor cells.

Where about on the tongue can we taste sweetness?
At the front
At the back
At the front and the back and on the sides of the tongue. Less in the middle.
Not every area of the tongue is sensitive to taste: most taste buds are located in the front and side of the tongue. It is interesting to note that there are no taste regions, as often assumed. All tastes are perceived in all places where there are taste buds (even if there are slight differences).

How does glutamate taste?

The Japanese chemist Kikuae Ikeda suspected that there was a fifth flavor besides sweet, sour, salty and bitter. In 1909, he proposed the name umami after identifying glutamate as a source.

What can a cat not taste?
Sweet
Sour
Salty
Due to a genetic defect in the receptor cells, cats cannot taste anything sweet. This mutation is not only found in the domestic cat but also in wild and large cats such as cheetahs and tigers. It is assumed that the mutation of the sweet receptor cells is related to their carnivorous diet.

What influence does it have on us to eat from a small plate?
You fill it more often and eat more
You take less and eat 10% less
You take less and eat 50% less
According to a study conducted at the University of Cambridge and the University of Oxford, eating from smaller plates helps to lose weight. This means that when eating, not only the taste but also the visual effects exert an influence on us.

If you don’t like coriander it’s because...
...you are allergic
...of your genes
...of an unpleasant experience related to coriander
The taste of coriander is associated with aldehydes, a special group of molecules. Some of these aldehydes are responsible for the popular fruity taste, while others are responsible for the penetrating soap taste. People who have the receptor for the latter in the nose do not like coriander.
