With the continuous improvement of living standards, people's demand for delicious food is also rising. From the color point of view, food is also quite rich. Red red beans, black black beans and white rice are all common, and these colors will also make people feel completely different. Under normal circumstances, blue food is not very common, and it will give people a feeling of loss of appetite. If this food is blue, it will give people a feeling of toxicity. In fact, this is also because many people have an illusion that they will unconsciously combine blue food with the plot of the movie, so they will feel that it is not delicious. Except blueberries, other blue foods are basically invisible.

In daily life, blueberry is also a kind of fruit with rich nutrition. It tastes sour and sweet, and it is loved by many people. The reason why blue blueberry won't make people lose their appetite is because it is so common that it won't make people have any illusions at all. After other foods are coated with a layer of blue jam, the nerves in the brain will reflect an idea, which will lead to disgust.

In fact, blue can calm the mood, which is why many people choose to go to the seaside for fun when they are in a bad mood. In fact, in real life, blue items will also give people a very elegant feeling. For people who prefer blue, they will also choose to buy blue daily necessities. The reason why they feel uncomfortable when eating blue food is also because most people will feel bad at first reaction after seeing blue food.

In fact, this has a direct relationship with the nervous system of the brain. The reason why people are afraid of food of this color is also because many toxic foods tend to be enchanting in color. The reason why foods such as red, yellow and green can be accepted by people is also because this kind of food often appears in front of them.
