To filter out bias and error in scholarly publications, a reseach process called Evidence Based Nutrition (EBN ) is now used to ensure the application of appropriate clinical decisions in the nutrition fields.
The medical field was the first to implement this type of research process which they call Evidence Based Medicine(EBM).
The medical field uses the PICO method to help researchers frame their thought processes during a search:
PICO stands for (Population; Intervention; Comparison; Outcome) (source: http://www.andeal.org/eal-terminology)
PATIENT/PROBLEM - What are the characteristics of the patient or population or problem?
INTERVENTION- What do you want to do with this patient or population or problem?
COMPARISON - What are the alternatives to consider?
OUTCOME - What are you trying to accomplish, measure, improve or affect?
Are you looking for therapy (treatment), Diagnosis, Harm/Etiology (identify causes for disease) , Prognosis (estimate patient's clinical course), Prevention?
