American researchers managed to describe it a cerebral mechanism that contributes to eating food just for pleasure.
Did you wonder why some foods are more delicious to you than others and can not stop eating? Scientists from the University of North Carolina School of Medicine (UCC) in Chapel Hill, North Carolina, USA, may find the cause: brain circuits
In laboratory experiments, Thomas Kash, a prominent professor at the Department of Pharmacology, and colleagues found a specific network of mobile communication that emanates from the region of the brain that processes emotions, motivating mice to continue eating delicious food, although their basic energy needs have been met, according to DPA / Diario Klarin.
The existence of this brain circle in mammals, described in an article in the scientific journal Neuron, can help explain why people often eat more in our modern surroundings of plentiful and delicious food. The circuit is a by-product of evolution, When high calorie foods were rare, our brains were designed to swallow as many calories as possible, as no one knew when the next super food would come.
"This circuit seems to be the way your brain tells you that if something really tastes good, then it's worth the price you pay for it, so do not stop it" Kash explains.
Scientists looking for obesity drugs have spent decades exploring and addressing brain cells and circuits involved in ordinary "homeostatic" dishes, which is caused by hunger and retains our energy level high. But this approach had limited success. More recently, some researchers are studying "hedon" foods, satisfying foods, high calorie foods that tend to go beyond our strict energy needs.
It is believed that the hedonistic diet reflects the prolonged adaptation of modern humans to ancient settings, where famine is common. Recognizing that calorie-rich foods are particularly tasty and pleasant and consuming whenever available, it has given it a key survival advantage by accumulating additional energy.
After that instinct, now in abundance, it can lead to obesity, a condition affecting only about 40% of adults in the United States only in terms of diseases such as diabetes, heart disease, and cancer.
