If you are interested in the effects of mental health and eating disorders on patients eating habits and nutrition then you could focus on this for your dissertation. Take a look at some examples we have created below:
Evaluating the short-term and medium term health effects of consisting upon a diet of nothing but Findus Crispy pancakes for four weeks: A consideration of autism spectrum eating disorders.
Autistic children often display obsessive food selectivity, which has been well researched; however, this study evaluates the effect on the adult body of eating only one type of food repeatedly. The choice of Findus Crispy Pancakes is based upon both its popularity with children and that it may be prepared in private at home and with basic cooking skills, a factor which may be relevant to the experience of autistic adults. Accordingly, this dissertation combines the theories of food and nutritional science with a practical experiment involving lifestyles. The researcher, medically checked prior to commencing their study, will spend one calendar month eating nothing by Findus Crispy pancakes (three meals a day). In addition to having their weight and general health checked by a doctor weekly, a video record will be kept of their mood and how their interactions change (if at all) with society. Thereafter, the findings of this study will be related to those of a similar nature previously carried out, and the positive and negative mental and physical health effects of such a diet presented.
