The Claim
Daily intake of 42 grams of walnuts for three weeks reduces serum LDL cholesterol by 7% and campesterol by 6% in healthy adults, indicating a potential effect on cholesterol metabolism independent of changes in gut microbiota.
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 42 grams of walnuts every day for three weeks lowers LDL cholesterol by 7% and campesterol by 6% in healthy adults.
See the scientific wording
Daily intake of 42 grams of walnuts for three weeks reduces serum LDL cholesterol by 7% and campesterol by 6% in healthy adults, indicating a potential effect on cholesterol metabolism independent of changes in gut microbiota.
Eating walnuts delivers fiber and fatty acids to the gut, which changes the bacteria living there. These bacteria make fewer bile acids that get reused by the liver. With less recycled bile acid, the liver pulls more cholesterol out of the blood to make new bile acid, lowering blood cholesterol levels.
What the research says
1 studyEating a small handful of walnuts every day for three weeks lowered bad cholesterol and a related marker in people who ate them, just like the claim says.
