The Claim
Among older adults, changes in circulating microRNAs other than hsa-miR-551a are not consistently associated with walnut consumption, as only one out of 53 initially identified microRNAs remained statistically significant after correction for multiple testing in a cohort of 330 participants.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults, eating walnuts does not consistently change the levels of most circulating microRNAs; only one out of 53 microRNAs showed a statistically significant change after accounting for multiple comparisons.
See the scientific wording
Changes in circulating microRNAs other than hsa-miR-551a are not consistently associated with walnut consumption in older adults, as only one of 53 initially identified miRNAs remained significant after correction for multiple testing in a cohort of 330 participants.
When older adults eat walnuts, only one specific microRNA in the blood changes consistently because most other microRNAs are too stable or not responsive to dietary signals, so their levels stay the same no matter what is eaten.
What the research says
1 studyScientists found that eating walnuts seemed to change many tiny molecules in the blood, but after checking carefully, only one molecule, hsa-miR-551a, really changed — all the others were just random noise. So yes, only that one molecule is reliably linked to walnuts.
