The Sugar Addiction

 

Stanford University health psychologist Kelly McGonigal writes that addictive substances, at first, release (or block re-uptake of) substances in the brain that stimulate pleasure, ecstasy, focus, or energy; however, the brain and body are not designed to sustain this state. The physiological function of the body is to maintain the systems in a state called homeostasis and avoid extreme fluctuations, which means the brain and body develop a tolerance to the effects of mind- and mood-altering substances (McGonigal). .
             For instance, when ingesting a drug that stimulates the flood of a neurotransmitter (i.e., dopamine), the brain may acclimate to this neurotransmitter by producing less dopamine or reducing receptors to uptake the substance, but as soon as the brain anticipates the body is going to consume the drug again, there is an anticipatory effect where the brain causes the production of dopamine to be reduced even further to counteract the anticipated effects of the drug, which sets the body up for intense cravings for the drug (McGonigal). This adaption process strengthens the addiction cycle with the addict requiring the drug to feel normal, and, now, research indicates that the same process is occurring with sugar (McGonigal). Researchers at Japan's National Institute for Physiological Sciences conducted a study to determine how the brain and body might adapt to the anticipation of consuming sweets and discovered that mice anticipating sweets release a chemical called orexin, which triggers the muscles of the body to uptake sugar that is in the bloodstream circulation and, thus, prepare for the anticipated blood sugar level increase initiated by the brain (Shiuchi et al). If an individual is able to resist the cravings then the blood sugar level drops and results in undesirable side effects of craving the sugar or a decreased ability to resist the temptation, which is comparable to the cigarette addict who craves a smoke or a heroin addict who needs a fix just to feel normal ((Shiuchi et al).
