Nutrition: Overview

NUT 4200 assignment -- July 2021

One detail -- 5 peer-reviewed articles, and at least three of the papers must be the original studies, not review papers

See box below titled, "Recognizing original research articles."

Also, (video) how to filter for original articles in ScienceDirect, Web of Science, and PubMed.  You cannot really filter with a button in APPsearch or Google Scholar.  But you should be beginning to recognize the original versus review anyway. (Note: I claim in this video that I eliminated everything but original studies from my PubMed results, but that's not true.  I filtered out only reviews, including systematic reviews and meta-analyses.  There would still be editorials and a small variety of other things.)

Quick links to databases, and getting help

Recognizing original research articles

Most of the articles you'll find using PubMed, Google Scholar, ScienceDirect, and other search interfaces will be original or primary research.  Not all.  You might also see editorials, commentary, news.  You'll often see reviews, systematic reviews, and meta-analyses and maybe evidence summaries, guidelines, or position statements.  All these are not considered original or primary.

Look for the standard format: short introduction, methods, results, and conclusions.  If your article is in this format, it's not editorials, commentary, news.

Look for terms like these in the title: review, systematic review, meta-analysis, evidence summary, guideline, or position statement.  If you don't see those, it's almost certainly original research.  (Those types are secondary.)

One area of confusion is this.  Many original research articles use data collected systematically by governments and other entities.  Other original research articles are based on original data, data that's not collected or measured or described elsewhere.  But original research does not have to have to start with original data.

Note that in some journals like the Journal of the Academy of Nutrition and Dietetics, original research is labelled "Original Research."  (This journal has an unusually high proportion of articles that are not original, but they're pretty well labelled.)
