Key result
Whole grapefruit lowers 2-hour postprandial blood sugar by ~10 mg/dl compared to grapefruit juice.
Why the study?
Whole fruits may provide better glycemic control than fruit juices, but this hypothesis requires evaluation in healthy subjects.
Do whole fruits improve glycemic control compared to fruit juices in healthy volunteers?
Do whole fruits improve glycemic control compared to fruit juices in healthy volunteers?
Absolute Event Rate: 97.6% vs 107.6%
p-value: p=<0.01
Consuming whole fruits rather than fruit juices may provide better glycemic control and positively influence blood pressure due to dietary fibers.
May favor whole fruit over juice for postprandial glucose control in healthy adults; leaves open effects in diabetes and long-term outcomes.
Background: Diabetes is regarded as a chronic disorder, which is globally spreading at an alarming rate and individuals are being pushed down by the burden of diabetes. Different measures and control programs have been conducted for awareness of this disaster endocrine disease as its associated complications. Objective: Current study has been conducted to evaluate the hypothesis that whole fruits provide better glycemic control than fruit juices. Materials & Methods: The study includes two groups of healthy volunteers, one group was on whole fruits while another group was supplied with fruit juices of same fruits and fasting blood sugar and random blood sugar were monitored. Results: Results revealed that whole grapefruit and orange fruit play effective role in maintaining random blood sugar levels in comparison to juices. Further suggested that dietary fibers are not only effective in regulating blood sugar, but also influence on blood pressure and pulse rate. Conclusion: Based on above findings, it has been concluded that type 2 diabetes patients can achieve better glycemic control by dietary fibers rather than juices, and it may be helpful in controlling diabetes related complication such as high blood pressure.

Gul et al. (2020) studied Healthy subjects (n=60). Whole fruits (Apple, Grapefruit, Orange) vs. 250 mL of respective fruit juice once a day was evaluated on 2-hour postprandial blood sugar levels (Grapefruit vs Grapefruit juice) (p=<0.01). Whole grapefruit significantly lowered 2-hour postprandial blood sugar levels compared to grapefruit juice (97.6 vs 107.6 mg/dl, p<0.01) in healthy volunteers.
