As early as 2010, 35.7 percent of American adults were obese, the highest level of obesity in U.S. history. There are numerous environmental factors that contribute to obesity, the majority of which are the number of fast food restaurants and the recent epidemic of binge eating. Evidence shows that binging on sugary, tasty foods increases dopamine in the brain and doing so creates addictive habits. Apparently there are several psychological and biological similarities between food addiction and drug addiction, including loss of control and cravings. One of the articles will examine environmental factors that may be contributing to the obesity epidemic and will also compare the medical similarities and differences between drug addiction and food addiction. Increasing rates of overweight adults and obesity have prompted a comparison of uncontrolled food and drug intake. It was smart to follow the biological concepts of addiction to explore the obsessive search for food; a model is needed to understand how food and drugs differ in their ability to control behavior. Another article will examine differences and commonalities in behavioral responses to food and drugs of abuse, with the goal of identifying new treatments for drug addiction or obesity.

It is mentioned that the study had articulated the mechanisms and behavioral pathways of how trauma and post-traumatic stress can cause an increase in causes of death in the United States...... middle of the document ......ect the impact of understanding food addiction on obesity and obese people. Studies have found that the apparently strong public acceptance of neurobiological clarifications about obesity and overeating can coexist with the idea that individual choice is the main cause of obesity. Obese people were more likely to support the view that obesity characterizes a dependency on certain foods. The apparent failure of neurobiological explanations of overeating and obesity in changing the public's view of obese people and obesity treatment suggests that these descriptions have not yet had the beneficial influences hypothesized by their proponents. As the idea of ​​food addiction takes hold, its advocates need to pay more attention to its effects on shame, treatment, and policy, and evaluate whether its net influence on public health might be harmful or helpful...
