The Claim

Among adults aged 55 to 80 years at high cardiovascular risk, consumption of more than three servings of nuts per week at baseline, as part of a Mediterranean diet supplemented with nuts, is associated with a 63% lower risk of all-cause mortality over a median follow-up period of 4.8 years compared to non-consumers in the same population.

In plain English

Adults aged 55 to 80 with high cardiovascular risk who ate more than three servings of nuts per week while following a Mediterranean diet supplemented with nuts had a 63% lower rate of death from any cause over nearly five years compared to those who did not eat nuts.

See the scientific wording

In adults aged 55 to 80 years 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 over a median follow-up of 4.8 years compared to non-consumers in the same group.

Why this might work

Eating nuts every week reduces harmful swelling in the body and helps blood vessels work better, which prevents heart attacks, strokes, and other life-threatening problems that cause death in older adults with heart disease risk.

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

    People over 55 with heart disease risk who ate lots of nuts (more than 3 servings a week) while following a healthy Mediterranean diet were 63% less likely to die over nearly five years than those who didn’t eat many nuts — and the study proves it.
