How Does Sugar Influence Decision-Making?

Improved Essays
According to Sugarscience (2006), for some people sugar can be an addiction, and they will have cravings and withdrawal syndromes together with chemical changes in the part of their brains, which is responsible for repeating, the mesolimbic reward pathway. Scientists from the U.S. National Institute on Drug Abuse (NIDA) demonstrated that sugar can cause changes in brains similar to cocaine and alcohol (Volkow and Li, 2004). People will have a higher desire for sugar intake (Avena, Rada, and Hoebel, 2008).
According to Vendruscolo, Gueye, Darnaudery, Ahmed, and Cador (2010), SOC is associated with mental health problems, and reward-related disorders. Investigating adolescent rats, Vendruscolo et al. declared that high sugar intake in adolescence

According to Pechmann, et al., due to experience and age, the adolescent’s brain is changing, especially in the “prefrontal cortex” and “amygdala” (2005, p. 206). The prefrontal cortex plays an important role in decision-making, uses previous experience to guide behaviors, and can slow down the stimuli to encourage activity; the amygdala converts feelings into emotions that can be influenced by teenagers’ increased levels of circulating hormones (Pechmann et al., 2005). The increased levels of hormones in adolescents’ bodies make them sensitive to stressors and strong emotional responses in their environments (Pechmann et al., 2005). Pechmann et al. declared that incompletely developed prefrontal cortexes and increased hormone levels make it harder for adolescents to overbalance the amygdala’s excitatory emotional responses, which result in “low control of impulses” that is manifested in unreasonable and perilous behavior happening more often than in either adults or children (2005, p. 209). Thus, according to Pechmann et al., adolescents have less of a chance than adults to make responsible decisions, and they are more likely to feel greater emotional instability, moreover reducing their ability to control their impulses

    When asked to agree or disagree with the primary statement of this clinical study, “Kids tend to get hyperactive after they’ve eaten lots of sugar,” I could not help but whole heartedly agree. As a summer-long camp counselor, an older sister to two, an early childhood education major, and as a former kid, I can honestly say that sugar does and (still can for me) induce a sense of hyperactivity. Sugar causes a rapid rise in blood sugar, therefore causing an intense increase in activity levels. This is why we know that campers 1 cupcake, they are bouncing off the walls. To investigate the effects of sugar on children, I have chosen to conduct a clinical study to determine this.…

    I consider that you have presented a good argument related to your selected topic. Your argument related to food, especially carbohidrates, and addiction has been well supported by many scholars. If your are going to consider addiction and neurological processes, I would advise you to consider the reward pathway theory (also called the mesolimbic pathway). Many researchers suggests that several types of addictions have similar brain patterns as in the case of drug addictions. To explain the reward pathway, it is important to understand the function of several brain structures: the ventral tegmental area (VTA), amygdala, nucleus accumbens (NA), the prefrontal cortex, and the hippocampus (Garrett, 2011).…

    The prefrontal cortex is the region that adults rely on and is involved in high level cognitive functions, such as, decision making (Blakemore, 2011). In teens, decision-making and other cognitive skills is heavily relied on another region, known as the limbic system (Bessant, 2010). As a result to relying on their limbic system, teens are susceptible to being highly emotional and impulsive. This explains why they engage in high risk behavior, such as unprotected sex (Blakemore, 2011), for example, Juno engaged in unprotected sex and as a result became pregnant. Initially, she went to the clinic to terminate the pregnancy; this decision is another example of how teens usually have the urge to make life changing decisions without considering the possible outcomes.…

    In a way sugar is needed for survival, but those that do a major binge on sugar suffer from more of a psychological disorder. There is a region in the midbrain called the hypothalamus; the hypothalamus is the "pleasure center", it controls the drive for food and sex. Having an hyperactive hypothalamus or Hypothalamic Dysfunction, a more proper psychological diagnosis, can result in someone contracting BED, Binge Eating Disorder. If someone has BED, a lot of the time they are not consuming the healthiest diet; and even when they get full they still continue to eat. There are chemical impulses, called neurotransmitters, that send signals and messages from one neuron to another.…

    “Adolescents’ judgment can be overwhelmed by the urge for new experiences, thrill-seeking, and sexual and aggressive impulses. They sometimes seem driven to seek experiences that produce strong feelings and sensations” (Frye). The urge for these sensations caused by hormones leads teens to commit actions and produce decisions that are atrocious. These horrid choices being made provides teenagers with the thrill that their hormones crave for while the teens, themselves, do not consider the consequences to their actions. A significant, real-world example of this according to the article, “Teenage Hormones, Sexuality and Mental Health” is that teenage hormones causes one feel more impulsive and more inclined to take risks, like experimenting with drugs or alcohol (Teenage Hormones, Sexuality, and Mental Health).…

    This means that teens are left vulnerable to making impulsive and risky decisions since most of their thought process is occurring in the amygdala which results in more emotional and intuitive decisions rather than more critical and analytical thinking. The combination of the early onset of puberty and the regular sequence of brain maturation result in most teenagers being ruled by emotions for almost a decade (Berger, 2016). Teenagers may look like adults but cognitively they are simply not there yet (Powell,…
