Eyes can tell how much a person loves chocolate, according to a study in the Journal of Evolutionary Psychology. Experts have concluded that the human brain responds to the taste of various foods so that it can be seen through the human eye.
This can be understood with the help of a special device for measuring the degree of liking of certain foods. If this method is approved for use in doctors' offices, it will become a revolution in nutrition.
According to experts, this method of research can help people who are addicted to certain types of food that are not good for them.
Dr. Jennifer Nasser, a professor at Drexel University, is leading this special study that uses electronic retinography to detect elevations in the neurotransmitter dopamine in the retina.
Dopamine has been linked to a number of pleasure-related effects in the brain, including the expectation of a reward.
On the retina, dopamine is released when the optic nerve responds to light.
Dr. Nasser and her colleagues found that electrical signals in the retina rose like a flash of lightning when a piece of chocolate was in the mouth of the study participants.
This increase was as large as if study participants had been given a stimulant to increase dopamine levels artificially.
The dopamine system of the eye can be used for eating problems, according to research by Dr. Nasser's team.
Food is both a means of providing energy for the body and a pleasure, but the side effect of overdoing it is extra pounds.
Dr. Nasser's team wants to develop a method to increase food pleasure and energy value while reducing side effects.
Electronic retinography is a very affordable method because it is relatively inexpensive - about $ 150 per session, which lasts 20 minutes.
