The Study
Effect of moderate walnut consumption on lipid profile, arterial stiffness, and platelet activation in humans
This study is like a fair test where people were randomly given walnuts or no walnuts to see what happens. It can tell us whether eating a small amount of walnuts changed things like cholesterol or blood vessel health in these men, but it can't tell us if walnuts help prevent heart attacks in everyone.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
