Make a list of all the types of people who might suffer from malnutrition in hospital - babies, old people, people with specific eating disorders (e.g. coeliac disease, bulimia, anorexia), anyone hospitalised long-term (is hospital food that great for good nutrition?). Then aim to write a page on each. Or at least a page of bullet points. Then do the barriers for each one. They're probably not quite all the same. And then write a conclusion. Sounds quite interesting to me... Goes away to cook dinner - would rather be writing essay. Will write essay for free childcare, meal-cooking and access to decent library.
