Research Paper (undergraduate) from the year 2010 in the subject Philosophy - Practical (Ethics, Aesthetics, Culture, Nature, Right, ...), grade: 1,0, Brandenburg Technical University Cottbus, language: English, abstract: Supermarkets offer a wide range of food products and people shop there, usually with no thought to the origin of the packaged food or how it was processed. The food industry is vague about ingredients and processing methods, and has little regard for the well-being of consumers and real nutritional requirements. Lifestyle diseases are the result of an unhealthy way of life, stress and the unawareness of individuals. While I had to undergo chemotherapy, I thought of how can I take on responsibility for myself. In this study I would like to give a brief insight into the issue of cancer as a lifestyle disease and its prevention via a health-conscious diet.
