I think Morgan Spurlock's experiment was unethical because he put his own health at risk unnecessarily. However, I do think it served a purpose in raising awareness about the potential health risks of consuming fast food on a regular basis.
6Yes, I believe documentaries like "Super-Size Me" can help change people's behavior with regard to fast food and nutrition by educating them about the potential risks involved in eating unhealthy foods.
The ethical issues raised in the documentary "Super-Size Me" include the potential health risks of consuming a diet high in fast food, the lack of nutritional information available to consumers, and the targeting of children by fast food companies.
