Black Bean (Phaseolus Vulgaris L.) Protein Hydrolysates Reduce Acute Postprandial Glucose Levels in Prediabetes and Normal Glucose Tolerance Adults

In Brief

A clinical study evaluating Black bean protein hydrolysates (BPH) and Commercial non-caloric beverage for PreDiabetes. Completed, enrolled 28 participants across 1 site.

Detailed Summary

This work aimed to evaluate the acute effect of a black bean protein hydrolysate (BPH) on glucose levels in adults with normal glucose tolerance (NGT) and prediabetes. Twenty peptides were identified in BPH, and a followed in silico predictive digestion showed a release of several short-chain peptides with potential hypoglycemic potential. A double-blind, placebo-controlled, randomized clinical trial was conducted on 28 adults with NGT or prediabetes. After consent, participants were randomized into two groups, placebo or the corresponding 5 g BPH treatment. An oral glucose tolerance test (OGTT) (75 g glucose) was used to measure glucose tolerance before treatment. A second OGTT was used to evaluate the acute effect of the BPH, and blood samples were collected at 0, 60, 120, and 150 min, and blood glucose levels were measured.

Interventions

Black bean protein hydrolysates (BPH)dietary

Participants were blinded to treatment and received BPH (5 g powder) dissolved in 120 mL of a commercial non-caloric beverage and immediately after an oral glucose tolerance test was performed to evaluate the postprandial effect of BPH.

Commercial non-caloric beverageother

Participants were blinded to treatment and received 120 mL of a commercial non-caloric beverage and immediately after an oral glucose tolerance test was performed to evaluate the postprandial effect of placebo.
