In order to conduct this research, the authors performed an oral history of Claire in order to have a deeper understand the underlying cause for her eating disorder. The oral history was a method that the authors use to have a better comprehension of how Claire responded to the pressures and circumstances around her. Prior to discussing about her eating disorder, the authors talks of her childhood and family background. The authors take note of the times when Claire felt disappointment and listed them as triggers. By discussing of her family background, the readers and the authors are able to have a better understanding of the participant. The authors conclude that the psychological and social factors are all involved in what they call as the “ matrix of eating disorder vulnerability” (Leavy and Ross 73). It can be determined that the stress and tensions in her family is one of the main triggers in her eating disorder. The authors believe that the combination of various factors including media can trigger eating disorders. By implying this, readers can assume that the authors are not biased and they want to be as neutral as possible. The authors explore this matrix through …show more content…
Wade does this by focusing on several studies that focus on the relationship between genes and eating disorders. Based on family studies, there is a higher amount of eating disorders among women who have relatives with eating disorders than with individuals who do not have any relatives with the illnesses. Berratini states that “twin studies of binge-eating, self-induced vomiting, and dietary restraint suggest that these behaviors are roughly 46 to 72% heritable” (20). The article also gives information on the difference in genes between normal individuals and individuals with the illness. Based on the molecular genetic studies, studies have “failed to find an increase allele frequencies of dopamine D3 and D4 receptor genes” in individuals with anorexia compared to those who don’t have the disease (Berratini 23). Through this evidence, the author is able to conclude that genetic plays a huge role in the development of eating disorders. By giving statistics and strong evidence, the audience can infer that the author is aware of his research. The article also links the genes to other issues such as anxiety disorders that are also involved in anorexia and bulimia. By making this statement, the author implies that eating disorders that root from anxiety and other psychological could result from gene mutations. This
