The eyes of a person reveal if he or she loves chocolate or something else, scientists from Drexel University discovered…
The scientists used electroretinography which measures retinal response to light, and the results showed that retinas emits very strong signals when a person puts a piece of chocolate in the mouth, just like when exposed to bright light.
As is known, the pupils dilate by the action of dopamine, a hormone of happiness in the brain. That’s why people who are drugged or in love have greater pupils. And now, this is also true for chocolate lovers.
Interestingly, the researchers found that the reaction of the eyes on food and medicine is very powerful, even more powerful than the reaction to light. Thus, we can say that really everything can be seen in the eyes, according to the Daily Mail.
