The benefit of eating more fruits and vegetables for preventing diabetes is less strong in older people than in younger ones, possibly because aging changes how the body responds to nutrients.
Scientific Claim
The association between fruit and vegetable biomarkers and type 2 diabetes risk is weaker in older adults, suggesting age may modify the protective effect of plant-based diets.
Original Statement
“We identified evidence of a significant interaction only between baseline age and both plasma vitamin C and α carotene (P value for interaction <0.001), with the inverse associations with type 2 diabetes being weaker in the oldest age group.”

Unknown Title
The study shows that eating more fruits and veggies is linked to lower diabetes risk, but it didn’t check if this link is stronger or weaker in older people, so we can’t say if age changes the effect.
