The Claim
Daily consumption of 30–60 grams of walnuts for one year reduces low-density lipoprotein cholesterol (LDL-C) by 9.07 mg/dL in adults aged 63–79.
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.
Eating 30 to 60 grams of walnuts every day for a year lowers LDL cholesterol by 9.07 mg/dL in adults aged 63 to 79.
See the scientific wording
Daily consumption of approximately 30–60 grams of walnuts for one year reduces low-density lipoprotein cholesterol (LDL-C) by 9.07 mg/dL in adults aged 63–79, as demonstrated in a randomized controlled trial with 330 participants, indicating a direct lipid-lowering effect independent of other dietary or lifestyle changes.
Eating walnuts every day introduces special fats that replace less healthy fats in the liver. This change tells the liver to make more receptors that grab bad cholesterol from the blood and remove it, lowering the amount circulating in the body.
What the research says
1 studyThis study found that older adults who ate a handful of walnuts every day for a year had about 9 mg/dL less bad cholesterol than those who didn’t, just like the claim says. The walnuts themselves caused the drop, not some other hidden factor.
