The Study

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

In simple terms

This study looked at a lot of people over many years and found that those who ate more fruits and veggies tended to live longer. But it didn’t make people change their diets — it just watched what they already did. So we can’t say eating more fruits and veggies made them live longer — maybe they also exercised more or didn’t smoke.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Key takeaways

Summary

Based on the study abstract and findings.

  1. 1Yes — even a small increase in fruit and veggie intake was linked to living over a year longer on average and preventing thousands of deaths across the population.
  2. 2People who ate the most fruits and veggies had a 10% lower chance of dying from any cause and a 15% lower chance of dying from heart disease.
  3. 3If everyone ate one more serving per day, about 3% of deaths could be prevented.
