Hedonic eating is a term that refers to eating for the sake of pleasure. Current research shows that the act of eating for pleasure is quite common. Many factors contribute to why an individual may derive pleasure from eating, including brain activity caused by food, environmental conditions, differences in what a person finds pleasurable, social influence, and whether it has become or less of an addiction. The common consensus of all this research (found for this review) on the reaction within the brain during eating shows that eating pleasurable foods causes electrical impulses in the brain through the cerebral cortex and amygdala. The amygdala is part of the brain's reward system; is responsible for the associations; memory; Pleasure; emotional reactions; aggression; fear, alcoholism and addiction. Stimulation of the amygdala causes the brain to release endorphins, particularly serotonin, which cause the feeling of pleasure in the brain. Because of this release, the amygdala remembers what caused that reaction and makes the person want to do it again. However, although the tongue is considered part of the digestive system and is linked to brain responses when eating, research by Oliveira-Maia, Roberts, Walker, Kuhn, Simon & Nicolelis on intravascular food reward suggests that taste itself does not It has nothing to do with the brain's reaction to sugars in food. The reaction is independent and occurs in the digestive system and bloodstream. This was discovered during their study on rats, comparing water bottles filled with different levels of glucose and directly injecting glucose into different parts of the venous system to see how the responses changed.
