Open WellbeingWhat the studies actually measured

Cholesterol and blood fats

Gingerand Total cholesterol

Two sources here, and they say different things: one measured lower total cholesterol and one found no clear difference.

How sure anyone can be

Moderate certainty, level 3 of 4

Further research may change this.

The most certain of the two findings here; each record carries its own.

The numbers reported

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

Two sources, newest first

We do not pick between these or average them into one number.

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.

    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

  • None gives a number at all, only which way it went.
  • Two give no likely range, so how precise those numbers are is unknown.
  • Two 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.
