The Claim
Daily walnut consumption for four weeks in middle-aged adults at risk for metabolic syndrome reduces waist circumference without altering soluble VCAM-1 levels.
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.
After four weeks of eating walnuts every day, middle-aged adults at risk for metabolic syndrome had smaller waistlines, but their levels of soluble VCAM-1, a marker of endothelial inflammation, did not change.
See the scientific wording
The reduction in waist circumference observed after four weeks of daily walnut consumption in middle-aged adults at risk for metabolic syndrome is not accompanied by changes in soluble VCAM-1, suggesting that the effect on abdominal adiposity may occur independently of measurable changes in endothelial inflammation.
Eating walnuts every day provides fats that change how fat cells in the belly store and break down energy, causing the belly to shrink without affecting blood vessel inflammation.
What the research says
1 studyPeople who ate a handful of walnuts every day for four weeks lost a little bit of belly fat, but their blood markers for blood vessel inflammation didn’t change. This suggests the walnuts helped shrink their waist without affecting inflammation.
