Evidence policy
How NeuroBite evaluates evidence
Nutrition research varies a lot in quality. To help you judge what you read, we label claims on our guides with one of four evidence levels.
Last updated
Strong evidence
Strong evidenceConsistent findings from systematic reviews, large well-designed trials or official health guidance. Example: iron is needed to make red blood cells.
Moderate evidence
Moderate evidenceSeveral good-quality studies point the same way, but some uncertainty remains about how large or reliable the effect is.
Limited / emerging evidence
Limited / emerging evidenceSmall, short or early studies, or results that are mixed. The idea is plausible but not established.
Insufficient evidence
Insufficient evidenceToo little research, or research of too low quality, to draw any conclusion.
What we look at
- Type and size of studies
- Whether studies included children
- Consistency across studies
- Guidance from health bodies such as the NHS, WHO, NICE and NIH
