People who eat about 66 grams more fruits and vegetables each day — roughly one extra apple or a cup of carrots — have a 25% lower chance of getting type 2 diabetes, according to blood tests that measure plant nutrients.
Scientific Claim
A composite biomarker score combining vitamin C and six carotenoids is associated with a 25% lower risk of type 2 diabetes per standard deviation increase, equivalent to consuming 66 grams more of fruits and vegetables per day.
Original Statement
“One standard deviation difference in the composite biomarker score, equivalent to a 66 (95% confidence interval 61 to 71) g/day difference in total fruit and vegetable intake, was associated with a hazard ratio of 0.75 (0.67 to 0.83).”

Assessment Explanation
The claim uses 'associated with' and reports the hazard ratio and confidence interval correctly. The translation to grams of intake is derived from the study’s own regression model and is appropriately framed as an association.

Unknown Title
Scientists found that people with higher levels of vitamin C and carotenoids in their blood — which come from eating more fruits and veggies — had a 25% lower chance of getting type 2 diabetes, and that extra protection came from eating about 66 grams more fruits and veggies each day.
