The brain rewards they eat salt, fat and sugar publishing feel-good chemical substances. Food can induce feel-good chemicals in the same way as drugs and alcoholEvolution, competitiveness and ingestion analgesia are factors for pleasure eatingBeing full welcomes compared with gnawing hunger pains, root(CNN)--On Thanksgiving, many of us will eat more than normal and then critically, waddle away with a buzz of Turkey and sweet potato.
Having a belly filled with alleviate food may feel like a warm hug from inside.
Evolution has given us the instinct to eat a lot each time we prepare for hard times is the drive to survive, like the squirrels storing prismeno winter .This is also fuels from competition: beating others from food.
Mind our rewards for this by publishing pleasure chemicals--in the same way as drugs and alcohol, experts say.
Scientists are studying that good feeling after eating call ingestion analgesia, literally relief of suffering from eating.
"There is no reward circuits make you enjoy eating," said Roger Cone, Professor and Chairman of Molecular Physiology and Biophysics at Vanderbilt University."If you don't eat, won't we can survive."
Efficient feeling assured survival of the species.
"For most animals and most of human history, we did not have surplus calories," said cone."Animals and humans, they had to work harder to survive; but now, with unlimited calories everywhere for most people and a huge reduction in the amount of physical activity, have become obese."
Despite the modern environment bombarded by appetizing ads and fast food, the wiring of the human brain has not changed. brain circuits reward release chemicals that comfort and meet.
Your choices healthier fast food
With such easy access to fat, salt and sugar are a recent development in human timeline, said Gary Wenk, author of "Your Brain food." "Our bodies our big-time rewards for these kinds of things we find them, when we eat them as much as possible because we believe that we don't know when I will see again.Cognitively, we know it is not true. "
The Agency rewards fatty, sugary foods by issuing salty, endogenous opioids, which help control pain. A study published in Nature neuroscience this year suggested that foods with high fat, high-calorie affect the brain in much the same way as cocaine and heroin. When rats eat these foods in quantities large enough leads to compulsive eating habits like drug dependence, the study found.
Although meal that is more as helped to survive mankind lean times, they are not so cheap now.
Full sense of satisfaction when compared with the gnawing pain of hunger, root that the aircraft with a comfort sleepy, relaxing some of us know as a food replaces food coma. Regulates over House as hormones are released and blood flowing to digestion, said Barbara Rolls, author of "Volumetrics Eating Plan," a diet plan based on feeling full, known scientifically as saturation.
"We will start off feeling not good and grumpy, then eat and feel good," he said.

The Agency has physical cues to tell us to stop eating? is an important question is whether we hear.
While traveling through the stomach, food should be easily digested to move in the upper intestine. as soon as it gets with this part, the intestines Release a hormone that tell the brain to stop eating now, says Wenk, Professor of psychology and Neuroscience at Ohio State University.
As food increases, the stomach is full, can change the blood glucose levels and hormone ghrelin, stimulates appetite, calms. sense of saturation must end the meal.
Despite these recommendations, diners frequently fails.
"Even when you're completely Overfilled and who cannot eat another bite, when something is delicious, to continue eating," says Wenk.
Cylinders, Professor of science at the University of Pennsylvania, has this advice: "I support people should not eat as food is the last."
Here are some tips:
• Eat when they feel a little hungry, but don't wait until you are because you will probably be overused.
• Stop eating when you are comfortable in full.
• Try this exercise: examines on a scale between 10 and how hungry you feel (with a very hungry and 10 as extremely full). during lunch, magazines ceased to understand where you are in this range, and stop if you're into five.
