In plain English

Populations that consume more fruits and vegetables have a 2.95% lower rate of death from all causes compared to those with lower intake.

See the scientific wording

Increasing fruit and vegetable intake by one quartile across a population could prevent approximately 2.95% of all deaths, suggesting a modest but measurable public health impact of dietary improvement at the population level.

Why this might work

Eating more fruits and vegetables delivers more plant compounds that reduce harmful molecules in the body, which decreases damage to cells and tissues over time, leading to fewer fatal diseases.

  1. Study: Fruit and vegetable consumption and mortality: European prospective investigation into cancer and nutrition.

    If everyone ate a little more fruits and vegetables — just enough to move up one group in how much they eat — about 3 out of every 100 deaths could be prevented. The study found exactly that.
