Researchers at the Max Planck Institute in Germany explain why people are inclined to eat a lot. The study was published in the journal Cell Metabolism.
According to the EurekAlert portal, this is due to the release of brain dopamine, which is the hormone that causes mood. According to experts, this hormone release occurs twice during meals: when eating and drinking at the stomach.
Two peaks of dopamine release
"With our new positron emission tomography method, we have not only been able to detect two dopamine peaks, but also to identify specific areas of the brain associated with these releases," he said. The lead author of the research is Mark Tithemeier.
The study involved 12 volunteers, some of whom took delicious drinks, and others made an arbitrary decision. By analyzing the data, scientists have discovered how much the demand for a tasty drink is, and when it is high in food, a small amount of dopamine is released.
"On the one hand, releasing dopamine shows our commitment to subjective nutrition, and our desire to release dopamine from the intestine," says another researcher Heiko Buses.
Consequently, dopamine excretion, which may lead to intestinal obstruction, has led us to overindulgence the products we need. "We eat enough until the dopamine is released," he concluded.
