The Claim

Consumption of peanuts is associated with reduced mortality in low-income populations, with an effect size comparable to that of tree nut consumption in higher-income populations.

What the research says

Supports is higher

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

In plain English

People in low-income populations who eat peanuts have the same lower risk of death as people in higher-income populations who eat tree nuts.

See the scientific wording

Peanuts, which are the primary form of nut consumed in low-income populations, show the same association with reduced mortality as tree nuts in higher-income populations, suggesting affordability does not diminish potential benefit.

Why this might work

Eating peanuts lowers harmful fats in the blood and reduces swelling in the body, which prevents blood vessels from getting clogged and reduces the chance of heart disease death.

  1. Study: Prospective Evaluation of the Association of Nut/Peanut Consumption With Total and Cause-Specific Mortality

    This study found that people who ate more peanuts—especially those with less money—were less likely to die from heart disease or other causes, just like people who ate more expensive nuts. So peanuts are a cheap and healthy choice.
