Cholesterol and blood fats

Gingerand LDL cholesterol

Only one source here so far, and it found no clear difference in LDL cholesterol.

How sure anyone can be

Low certainty, level 2 of 4

Further research is likely to change this.

The numbers reported

No number has been put on this yet. One source recorded only which way the numbers went — for now, that is all we have here.

One source, newest first

What we read is the published abstract, not the full paper, so a blank below may still be printed in the paper itself. A fixed rule worked this out from the source’s own fields. Nobody checked this rating by hand.

    Imprecision stops at the first check that applies; others may apply too.

    AI-reviewed & signed — an AI agent re-read this finding against the saved source and checked that the quote, the numbers, the units and the direction match it. No person read it. The owner authorised the agent to sign the batch with the owner's key, and every build rechecks that signature against these exact bytes.

What is still missing from these readings

  • No number at all, only which way it went.
  • One gives no likely range, so how precise that number is is unknown.
  • One do not say how many people took part.
  • Amount taken — Not in the abstract.
  • For how long — Not in the abstract.

Something nobody wrote down is never a zero and never a guess.

Still to read for Ginger

Six of the 19 things on our list for Ginger have no reading here yet:

  • Basal Metabolic Rate
  • Fasting insulin
  • Oxidative stress (F2-isoprostanes)
  • Platelet Count
  • Serum cortisol (morning)
  • Waist circumference

Still to read means nobody here has got to it, not that it was tried and did nothing or that no research exists. A pairing on no list is not a gap: we never set out to read it.
