People with the highest levels of fruit and vegetable biomarkers in their blood are about half as likely to develop type 2 diabetes as those with the lowest levels.

Scientific Claim

Individuals in the highest quintile of the composite biomarker score (top 20% of fruit and vegetable intake biomarkers) have a 50% lower risk of developing type 2 diabetes compared to those in the lowest quintile.

Original Statement

“A composite biomarker score... was inversely associated with type 2 diabetes with hazard ratios... 0.50 for groups 2-5 compared with group 1 (the lowest group).”

Assessment Explanation

The hazard ratio of 0.50 is correctly reported as a comparison between groups, and the language does not imply causation. The finding is consistent with the study’s observational design.

Similar Assertions

People who eat at least five servings of fruits and vegetables a day — as estimated by blood tests — have about a one-third lower risk of developing type 2 diabetes than those who eat less.

81%

Adding a little more fruit and veggies to your diet helps a lot if you’re eating little now — but adding even more beyond that doesn’t help as much.

80%

Blood tests for fruit and vegetable nutrients are better at predicting diabetes risk than asking people what they ate, because people often misremember or misreport their diet.

80%

Even after accounting for body weight, people who eat more fruits and vegetables still have a lower risk of type 2 diabetes, meaning the benefit isn’t just because they’re thinner.

72%

Eating more fruit and vegetables together doesn't seem to lower the risk of type 2 diabetes, according to a review of four large studies tracking thousands of adults over many years.
