Any material that is challenged or likely to be challenged must be supported by a reliable source. "Original research" is an assertion for which no reliable source can be found; it is not attributable. The only way you can show that your edit is not original research is to produce a reliable published source that contains that information. However, even with well-sourced material, if you use it out of context or to advance a position not directly and explicitly supported by the source, you are also engaged in original research; see below.
