The Claim

One year of walnut consumption increases circulating levels of hsa-miR-551a in adults aged 63–79, and this increase does not mediate the reduction in LDL-cholesterol, indicating that the lipid-lowering effect occurs through other biological pathways.

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.

How it works
1 study reviewed
In plain English

Eating walnuts daily for one year raises levels of a specific microRNA called hsa-miR-551a in adults aged 63–79, but this change does not explain why LDL cholesterol decreases. The cholesterol reduction happens through different biological mechanisms.

See the scientific wording

One year of walnut consumption increases circulating levels of hsa-miR-551a in adults aged 63–79, but this change does not mediate the reduction in LDL-cholesterol, indicating that the lipid-lowering effect occurs through other biological pathways.

Why this might work

Eating walnuts every day for a year increases a specific blood molecule called hsa-miR-551a, but this molecule does not affect bad cholesterol levels. The cholesterol drop happens through a different process in the body.

  1. Study: Interplay of Walnut Consumption, Changes in Circulating miRNAs and Reduction in LDL-Cholesterol in Elders

    Eating walnuts for a year raised a specific blood molecule called hsa-miR-551a in older adults, but that rise didn’t cause their bad cholesterol to drop—so walnuts lower cholesterol in some other way.
