Industry-funded study of the week: OLIPOP (prebiotic soda)

Here is yet another industry-funded study with a predictably favorable outcome, this one about a drink containing 6 grams of dietary fiber shown in this study to reduce blood glucose levels after consumption.

The study: Prebiotic soda lowers postprandial glucose compared to traditional soda pop: a randomized controlled trial.

Conclusion: a prebiotic soda is a favorable alternative to traditional soda formulations for managing postprandial blood glucose levels and maximal glucose excursion in generally healthy adults with overweight or obesity.

Competing interest statement: This study was funded by the manufacturer of the prebiotic soda beverage, OLIPOP, Inc. CFM, TB, EM, VK, and CC were employees of Biofortis, Inc., a Contract Research Organization that received funding from OLIPOP, Inc. to conduct the study. NV, MJM, and CM were employees of OLIPOP, Inc., the study sponsor company. AMV was a consultant of OLIPOP, Inc. for research support at the sponsor’s request.

Funding Statement: This study was funded by OLIPOP, Inc.

Comment: I particularly wanted to include this one because it is so blatantly done for commercial purposes, funded by the maker of the soda and conducted by employees or consultants. It belongs in the Journal of Industry-Funded Research, if such a thing existed. Adding fiber to sodas to feed your microbiome? I’d rather get mine from vegetables, grains, beans, nuts, and fruits.
