The Claim

Among older adults at high cardiovascular risk, those who consumed more than three servings of nuts per week at baseline and were assigned to a Mediterranean diet supplemented with nuts experienced a 63% lower risk of all-cause mortality compared to non-consumers in the same group.

Cause and effect
1 study reviewed
In plain English

Older adults at high risk for heart disease who ate more than three servings of nuts per week and followed a Mediterranean diet with added nuts had a 63% lower rate of death from any cause than those who did not eat nuts, even when both groups had the same heart disease risk level.

See the scientific wording

In older adults at high cardiovascular risk, those who consumed more than three servings of nuts per week at baseline and were assigned to the Mediterranean diet supplemented with nuts had a 63% lower risk of all-cause mortality compared to non-consumers in the same group, suggesting a synergistic effect between baseline nut habits and continued nut intake.

Why this might work

Eating nuts regularly reduces swelling in blood vessels and makes the lining of blood vessels work better, which prevents heart attacks and strokes, leading to fewer deaths.

  1. Study: Frequency of nut consumption and mortality risk in the PREDIMED nutrition intervention trial

    People who already ate nuts and were given more nuts as part of a healthy Mediterranean diet were much less likely to die over the next few years than those who didn’t eat nuts—even if both groups had the same heart disease risk.
