Acute ingestion of snake fruit jelly improves glycemic response, enhances endurance performance and antioxidant defense, and reduces inflammatory markers in healthy adults
Abstract
Background: Snake fruit is rich in vitamin C, carotene, phenolic compounds, flavonoids, and monoterpenoids - bioactive constituents known for their potent antioxidant properties. Based on these components, the present study investigated the potential effects of snake fruit jelly ingestion on glycemic control, endurance performance, alongside its impact on antioxidant status, inflammatory responses, and metabolic biomarkers in healthy individuals.
Methods: A randomized crossover design was used in two separate experiments involving 48 healthy sedentary men and women aged 19-35 years. All participants ingested 140 g of both control jelly and snake fruit jelly on separate occasions. Experiment 1 (n = 25): Blood glucose (BG) concentrations were measured at baseline and every 30 minutes for 2 hours post-ingestion. Experiment 2 (n = 23): Following each jelly ingestion, participants performed leg cycling at 60% of peak oxygen consumption until exhaustion. Blood samples were collected before and after exercise to measure BG, insulin, cortisol, and biomarkers of antioxidant status and inflammation.
Results: In Experiment 1, BG concentrations at 30 and 60 minutes post-ingestion, as well as the incremental area under the BG curve at 30, 60, 90, and 120 minutes, were significantly lower following snake fruit jelly ingestion compared with control (all p p p < 0.05). Cortisol and interferon-gamma concentrations showed no significant differences between conditions.

How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 48 participants or records.
