Why do people still find it difficult to resist delicious food?

This cannot be blamed on us being too greedy, but has something to do with the brain mechanism.

During the process of enjoying food, the brain secretes dopamine twice when the food is in the mouth and when it enters the stomach. This mechanism may increase the desire for food and delay the brain's "full" signal.

Dopamine is a neurotransmitter that transmits messages of excitement and pleasure and is a key component of the brain's "reward effect."

Dopamine works with another substance in the brain, opioid peptides, to produce feelings of pleasure.

If certain actions cause the brain to secrete dopamine and opioid-active peptides, the brain will cause the body to repeat those actions over and over again.

Using positron emission tomography, scientists not only discovered two peaks of dopamine secretion during eating, but also found specific areas of the brain related to these two dopamine secretions: the first secretion occurs in areas related to reward and sensory perception.

area. The second secretion of dopamine after food enters the digestive tract occurs in areas related to higher cognitive functions. The second secretion of dopamine induced by the intestines will send a "full" signal, while delayed secretion will cause people to overdose.

Diet, by the time the second secretion occurs, you have already eaten enough.
