Aspartame has made its way into most American foods. It is labeled as a positive healthy sugar supplement but has more to it than what meets the eye. After many research studies it has been found to have many negative effects on the human body. These negative effects are anywhere from effecting the human brain, to causing disease and health conditions, to promoting weight gain.  One way I could establish credibility in my paper is presenting the results of research studies having to do with aspartame. I could gain emotional appeal by presenting information about health issues, and logic by presenting steps to prevent this type of harm.
