California, Most people find food to satisfy the tongue and stomach. But for people with anorexia, food is something that should be avoided. Why are people afraid or not hooked anorexic eat?
A study at the University of California finally reveals the reason why people who suffer from anorexia are not fond of or avoid the food.
The study, led by Walter Kaye, a professor of psychiatry at the University of California, San Diego School of Medicine, found that food affects the brain that trigger anxiety in people who suffer from anorexia.
Most people looking for food to find the experience enjoyable and beneficial to the body. But people with anorexia nervosa often say the food made him more anxious and refusal of food will make her feel better.
Research over the past decade has provided new knowledge into the brain mechanisms associated with pleasant aspects of food. One of these brain chemicals are dopamine, which is released when people or animals eat delicious food.
The new study by Walter Kaye using brain imaging technology called Positron Emission Tomography (PET), which allows the visualization of the function of dopamine in the brain.
To provoke the levels of dopamine in the brain, researchers gave doses of amphetamines, which can release dopamine in the brain.
In healthy women without eating disorders, amphetamine stimulates dopamine release associated with an extreme sense of excitement in the brain known as the center of the ‘prize’.
However, in people who have anorexia nervosa, amphetamines made her feel anxious and active part of the brain is the opposite, namely that made her feel worried. This is what ultimately makes anorexics avoid the food.
If most people have great difficulty in diet and weight, individuals with anorexia nervosa can diet by itself, even life-threatening.
Based on new studies that have been published in the report International Journal of Eating Disorders, eating disorders have very high death rate due to starvation.
