People who eat the most fruit generally have better insulin sensitivity and lower blood sugar levels after eating.
Claim Context
Total fruit intake in adults is associated with an inverse correlation with insulin secretion and a positive correlation with insulin sensitivity, resulting in lower postprandial blood glucose concentrations in those with the highest intake.
“The participants were allocated to four groups according to their median total fruit intake at baseline, and this was found to correlate inversely with insulin secretion and positively to correlate with insulin sensitivity. Moreover, the postprandial blood glucose concentration was significantly...”

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether increasing total fruit intake directly improves insulin sensitivity and lowers postprandial glucose.
A randomized trial of 200 adults with insulin resistance, randomized to a high-fruit diet vs. a standard diet for 8 weeks, using hyperinsulinemic-euglycemic clamps to measure insulin sensitivity.
The long-term association between fruit intake and insulin sensitivity markers in a large population.
A prospective cohort study of 10,000 adults measuring insulin sensitivity and fruit intake at multiple time points over 5 years.
The current relationship between fruit intake and insulin sensitivity in a specific population.
A cross-sectional study of 1,000 adults measuring fruit intake and HOMA-IR simultaneously.
