The Claim

Nut consumption is associated with significantly lower mortality from cardiovascular disease, cancer, respiratory disease, infectious disease, renal disease, and liver disease, but not with diabetes or Alzheimer’s disease mortality, in a large cohort of middle-aged U.S. adults followed for 15.5 years.

Support is ahead, but a single strong opposing study can change this.

In plain English

People who eat nuts have lower death rates from heart disease, cancer, lung disease, infections, kidney disease, and liver disease compared to those who do not eat nuts, but there is no difference in death rates from diabetes or Alzheimer’s disease.

See the scientific wording

Nut consumption is associated with significantly lower mortality from cardiovascular disease, cancer, respiratory disease, infectious disease, renal disease, and liver disease, but not with diabetes or Alzheimer’s disease mortality, in a large cohort of middle-aged U.S. adults followed for 15.5 years.

Why this might work

Eating nuts lowers harmful inflammation and damage from free radicals in the body, which protects the heart, lungs, liver, kidneys, and immune system from failing, but does not fix the specific problems that cause diabetes or Alzheimer’s disease.

    People who ate nuts regularly were less likely to die from heart disease, cancer, lung disease, infections, kidney disease, or liver disease, but eating nuts didn’t change their risk of dying from diabetes or Alzheimer’s — just like the claim says.
