Why?
Because peer reviewed journal articles are researched and written by professionals in each academic field. This written research is then evaluated by the editorial boards of professional journals. The editorial boards are made up by professionals in the field, thus giving a stamp of approval by a jury of peers to the research.
If you use sources that are peer reviewed, this will show that you have selected content that has been accepted as scholarly and worthy of publication rather than just a news or opinion source.
