The principles of research
- Recognition of credible sources
- Evidence based information
- Accurate analysis of data
Recognition of credible sources - general
Trustworthy, unbiased, + independent sources.
- Experts in their field
- Government bodies + educational institutions
Evidence-based information - general
Assessing the evidence that went into the formation of the information (info should be based on evidence/proof).
- Peer-reviewed journal articles
- Literature reviews
- Food modelling system
- Controlled randomised testing
Accurate analysis of data - general
Data needs to be accurately analysed in order to draw objective, unbiased inferences from the evidence (not just choosing data sets that support own hypothesis).
- Unbiased + objective data analysis
- Assessment of all relevant data
- Assistance from those outside the study
Recognition of credible sources - ADG’s
- NHMRC
- Dietary Guidelines Working Committee comprised of experts in the field of health, nutrition, + food.
- Dieticians Association of Australia
Evidence-based information - ADG’s
- Evidence Report containing over 55,000 peer-reviewed journal articles.
- 2003 Guidelines + their support documentation.
- Food modelling system
- Key authoritative gov reports.
Accurate analysis of data - ADG’s
- Rigorous research methodology used in systematic literature reviews.
- Evidence graded using NHMRC protocols (several grade A).
- Assistance of expert methodologist (ensures accuracy, no bias, + consistency).
