- Endpoints
CVD, mortality.
- Statistical methods
None.
5. Actual results
- Results
Argues that recent meta-analyses found no benefit of reducing SFA on CVD and total mortality; SFAs raise LDL mostly as larger particles; whole-fat dairy, unprocessed meat and dark chocolate not associated with increased CVD risk.
- Absolute risks
not applicable
- Authors' conclusion
Totality of evidence does not support further limiting intake of SFA-rich foods such as whole-fat dairy and unprocessed meat.
6. Strengths
- Food-matrix perspective
7. Weaknesses
- Narrative, non-systematic
- Possible COI
- Disagrees with Cochrane I-FAT-01 on CVD events
8. Risk of bias
- Orienting tool
- none applicable
- Type of assessment
- simplified assessment (abstract only)
- Full formal assessment
- no
- Overall risk of bias
- high
- Rationale
Narrative advocacy review.
9. Assessment of the statistical interpretation
None.
10. Relevance to the specific claim
Supports C-FAT-01 partly (minority view).
11. Independent contrary findings
12. Transferability to Germany and Europe
Moderate.
13. Overall methodological judgement
Minority expert view; useful for fairness but low evidential weight.
