Humans are sweet because of 'hunger and pleasure'?

Why do we still have a delicious dessert after enjoying a full meal, even if you know it is not good?

According to psychologists, it is because the stimulated dessert from feeling "satisfied and happy" rather than hunger. In other words, your brain is connected to the feeling of 'being rewarded' when you taste sweets, even when your stomach is full.

We eat dessert after a meal not to restore energy
for the body that comes from the "satisfying, happy" feeling in the brain.

DailyMail reported that the University of Naples research team found that we eat desserts because the chemical signals of 'satisfying' in the brain are activated, and this can cause overeating. or obesity. This phenomenon is also known as 'hedoin hunger'.

Lead researcher Dr. Palmiero Monteleone said: 'Eating dessert sweets comes from the desire to eat to be happy, to enjoy rather than to restore energy to the body'. Even so, the whole process of psychological evolutions behind eating because of this 'pleasure' has not been thoroughly understood by science. It is likely that the 'reward' mechanism regulators in the brain (like ghrelin and 2-AG compounds) interfere with this process.

Dr. Monteleone came to this conclusion after monitoring 8 healthy adults, aged 21-33. First, they were invited to eat their favorite dishes and for the second time, they were asked to eat a less 'delicious' menu, with equivalent calories and nutrition. The results showed that the levels of ghrelin and 2-AG both increased while volunteers ate 'pleasure' (ie their favorite foods), but remained unchanged at the next meal.

Monteleone hopes that understanding the psychological mechanism of 'pleasure' will help science better understand the epidemic of obesity that is raging in developed countries. This study will be published in the June issue of Endocrine Society's Journal of Clinical.
