Introduction The concept that some foods may be addictive has become popular in the recent years. Both animal and human models maintain far-reaching overlap between the neuronal signaling associated with consumption of delicious foods and substance addiction. On the other hand, some people are unable to stop eating particular foods in spite of their efforts to stop consuming these foods (Burke et al., 2016). They continue to eat these foods not quench their hunger, but to feel better emotionally. Even though food addiction may result in weight gain and overconsumption of calories, it is not the same as obesity (Burke et al., 2016; Ziaudden and Fletcher, 2012). The idea of food addiction is controversial. However, it has substantial effects …show more content…
Though, the majority of people consume unhealthy foods due to emotional reasons, but not as a result of the paucity of information. Food addiction appears plausible since the brain pathways that changed to react to natural rewards are triggered by addictive substances (Avena et al., 2008; Davis, 2013). Palatable foods such as sugar have the same characteristics as substances that produce dopamine and opioids. Hence, sugary foods may have addictive potential. The belief that some of the drugs may lead to addiction raises the probability that even some types of food result in food addiction. The study indicates that some people are forced to consume sweet foods in the same way alcoholic may feel forced to drink (Avena et al., 2008). Avena et al., research focused on sugar dependence evidence in a model of animal (Avena et al., 2008). The researchers analyzed four addiction components (bingeing, cross-sensitization, craving, and withdrawal). Further, they related these behaviors to neurochemical changes that take in the brain, and also occur with addictive substances such as alcohol. Neutral systems that progressed to stimulate and reinforce foraging and …show more content…
Avena et al., found that irregular availability of sugar to rats caused binge-like manner drinking. This stimulated the release of DA in the nucleus accumbens, the same as the typical influence of drug abuse. The release of DA in the nucleus accumbens results in alterations in the availability of extracellular dopamine receptor. Irregular availability of sugar to rats also acted like opioids in the brain (Avena et al., 2008; Baik et al., 2013). The researchers identified significant changes of opioid systems, for instance, declined enkephalin mRNA expression in the NAc(Avena et al., 2008). Therefore, the symptoms of withdrawal appear to be an influence of opioid changes because withdrawal can be achieved by antagonist naloxone of opioid. Surprisingly, food deprivation also has the ability to indicate opiate-like withdrawal symptoms (Avena et al., 2008).Withdrawal condition entails not less than two neurochemical manifestations. The first manifestation involves a decline in the extracellular DA in the NAc. Another manifestation entails the release of Ach (acetylcholine) from accumbens interneurons (Avena et al., 2008; Gearhardt et al., 2011).Adaptations of neurochemical in reaction to irregular sugar consumption imitate the influences of opiates(Dileone et al., 2016). It is postulated that irregular, large consumption
Stress not only affects the amount of food intake as well as the diet, but it can also affect the desire to eat these foods. A previous study examines the relationship between psychological stress and its association with appetite, generating a concept called “Reward Based Stress Eating” (Adam 2007). A model is generated and analyzed to expose cortisol’s influence on eating as a reward and how it affects food choices. This experiment is unique because although it is not as hands on in regards to measurements like others, it utilizes knowledgeable pathways to derive how brain circuitry alters motivation to crave foods. They conclude that stress stimulates the release of opioid internally, a hormone that counteracts stress’ activity on the HPA axis and to help relieve it of its desires. By using frequent stimulation, they note that the HPA will eventually promote the desire on appetite; moreover, cortisol will also stimulate the concept of food acting as a reward. The results expose glucocorticoids possessing a potential role in stimulating food intake and helping lead to obesity due to the system’s imbalance when conflicted with both the opioids and the stress. In a recent study, women were observed to analyze the relationship between perceived stress, chronic stress, and the motivation to eat food (Groesz 2010). 561 women were surveyed online and filled out forms regarding general information such as age, weight, stress, and eating behavior. With this data, the amount of perceived stress was measured and averaged (M=1.68) through the Perceived Stress Scale, a questionnaire providing different questions with personal answers as responses; in addition, a Social Stress Index was utilized to measure the environments of stress...
That craving is what powers the habit loop” (pg33). Craving is the actual fuel that starts the habit loop to a rotating cycle, without the feeling of crave there’s no habit loop since the individual doesn’t have any intention to seek rewards. Wolfram Schultz a professor of neuroscience at the University of Cambridge conducted an experiment with a monkey named Julio; the purpose of the experiment was to examine how Julio’s brain would react when Julio followed a procedure of touching a lever when the colored shape appeared on a monitor then Julio was rewarded with a drop of his favorite blackberry juice. While repeating this experiment, Schultz has seen an unusual activity inside Julio’s brain, where at first Julio’s brain activity started spiking when he was rewarded with drop of blackberry juice; however, as the experiment continued its brain activity started spiking when the cue appeared on the screen. Julio’s brain had developed a habit; “… habit only emerges once Julio begins craving the juice when he sees the cue” (49). Now that Julio has developed a craving for the blackberry juice, he will automatically follow the habit. This experiment clearly proves how significant craving can be since it drives the habit loop. Likewise, I crave the reward of finishing my schoolwork while relaxing to the music since; it allows me to release the stress that’s been pilling up inside my brain from
In Michael Moss’ “The Extraordinary Science of Addictive Junk Food” he argues that companies have a huge influence on what consumers purchase and have been successfully able to get people addicted to junk foods because one’s willpower does not overpower their lack of adequate information and time, vulnerability to manipulative marketing and formulation of products, and their socioeconomic status.
The sole purpose of a company is to offer goods and services while making a profit. If people have a liking for food products with so many unhealthy items and are willing to buy them, the companies have no obligation to reduce the amount of added ingredients. The companies aren’t the ones forcing the public to overeat. However, these companies shouldn’t market their products to people who they can easily exploit like children and those who are penurious. Michael Moss, author of the article “The Extraordinary Science of Addictive Junk Food” interviews several people who worked for certain big brand companies and gives us an abundant amount of information on how the food companies make and market their food to “get us hooked”.
Drug addiction is often characterized as being a complex brain disease that causes compulsive, uncontrollable, drug craving, seeking and use without any regards to the consequences they may bring upon themselves, or society. As long as the brain is exposed to these large amounts of dopamine on the reward system, it will inevitably develop a tolerance to the current dopamine levels, which it is receiving, lessening the pleasure the user will experience. In order to satisfy the brains “reward...
Eating has taken its toll on people who live in the United States. One of the largest problems that people have is deciding how much to eat and what is healthy to eat. It was determined in the 1930s-1940s that the brain has a tremendous impact in controlling our eating habits. The main part of the brain, which controls this, is the hypothalamus. Basically, the hypothalamus measures different levels through out the body, especially in the stomach, to determine if our body needs food, which causes the sensation of hunger.
Growing rates of overweight adults and obesity have prompted the comparison between the uncontrolled intake of food and drugs. It has been smart to follow biological concepts from addiction to explore obsessive food seeking; a model is needed to understand how food and drugs differ in their ability to control behavior. Another article will look at the difference and commonalities in the behavioral responses to food and to drugs of abuse, with the goal to identify and new treatments for drug addiction or obesity.
Eating the pizza instead of the salad seemed like a good idea at the time, but now one is stuck in this sloth like state hours later. It seems letting cravings control what and how to eat is not the best strategy to healthy living. Mary Maxfield, in her article “Food For Thought: Resisting the Moralization of Food” discusses her views on how people should eat. She believes people crave what their bodies need, therefore, people should eat what they crave. Maxfield claims that diet, health, and weight are not correlated with each other, and because of this, people view obesity as unhealthy, thus forcing them to distinguish “right, healthy” foods from the “wrong, unhealthy” choices.
With this being something that I had practically daily, I knew that it would be the right item to choose for this reaction study. The first day that I went without the Strawberry milkshake from CookOut, I could immediately feel withdrawal from it, as if something was missing. At first, I was sure if it was because this was sort of my "reward" for completing daily tasks, because of the fact that it does contain a lot of sugars, or if it had become such a routine that my day just felt incomplete without it. Now, after seeing how sugar can be similar to addiction, I know that is definitely a reason why I was feeling this way and believe that it is a combination of all three. There were no real environmental factors that made it difficult to avoid the milkshake because I do not live near CookOut and do not have to pass it on my daily drive to school and work.
Gradually obesity, overweight, and other chronic health problems are starting to become more apparent in more individuals. Most studies have shown that individuals that are eating poorly don’t have the proper knowledge on how to eat a balanced meal. Being surrounded by so many options can overwhelm a person which can lead them to making the poor choice. In food psychology, understanding why certain people make certain food choices has made food psychologist realize that many individuals lack the knowledge of nutrition. By educating individuals on how to make better food choices and guiding them in the right direction it is possible for them to have a healthy life.
The addiction phase brings withdrawal symptoms that effect one’s daily lifestyle, and thus activate the anti-reward system. The anti-reward system plays a major role in the occurrence of aversive effects in the body like jitteriness, and nausea; and responsible for the negative-reinforcement that occurs through resumed drug taking. Negative reinforcement is responsible for bringing the aversive effects that occur during withdrawal (i.e., when one intends to stop consuming the drug). This highlights the importance of the neuroadaptations that occur with prolonged drug use and can occur with during over-consumption of caffeine (Meyer & Quenzer,
Many people in America, from toddlers to the elderly, have shown numerous signs of bad health. People have the desire to keep on eating due to more, new things being merchandised as “new and improved items” from the producers. For example, nowadays, people are eating pure junk that they find satisfying on the grocery food shelf. As, stated by Michael Pollan, in his article, “Eat Food: Food Defined” he affirmed that “real food is the type of things that our

With a fuller and clearer picture of the bodily systems, and how they respond to food, we see that overeating and obesity is not only about self-control; it has turned into a complex physiological problem. There is a cycle: a cue triggers a dopamine fueled urge. The dopamine then leads us to eat more food. Eating food leads to the release of opioid, and the production of dopamine and opioids both stimulate further eating. “Cues ensure that we will work hard to obtain the reward” (Kessler, 2009, p.54 ), but the desire for reward is causing overeating and obesity problems.
How do you know when you are addicted to something? Is it a choice or just an effect? What most people do not understand, is that no one really chooses to be an addict. Being addicted to something such as drugs, alcohol, and food, is not due to someone waking up one day and choosing to not be in control. It is mostly due to deeper issues like depression, influences upbringing and where you live, things, which lead someone on the path for their search of an escape.
