About
Diet and dietary ingredients can have a profound effect on gut microflora, both positive and negative. The reported effects on low and non caloric sweeteners (LNCS) on human gut microflora are contradictory in some of the in vitro and rodent studies. More specifically, the latter studies, using doses above the acceptable daily intake (ADI), suggest that LNCS may have adverse effects on gut microflora whereas recent data from human RCTs, using doses at or below the ADI, show little to no effect. In this study we will compare the effects of a low energy beverage made with steviol glycosides vs. a beverage made with sucrose on human gut microflora profile and function in a double blind, randomized study. A sucrose beverage was chosen as a control as it represents a caloric sugar sweetened beverage which is commonly consumed.
Full description
This is a double blind randomized parallel study with 2 treatments to understand the effects of a low energy steviol glycoside beverage vs. a sucrose sweetened beverage on gut microflora profile and function over 28 days.
Participants will have a daily exposure to each test product for 28 days. (1) steviol glycosides (flavored water, steviol glycosides) and (2) sucrose (flavored water, sucrose). Individuals will be supplied with fecal collection kits to collect stool samples. The volunteers will be advised to collect a fecal sample before week 0(baseline), week 4(study end) and week 8(follow up period). Fecal microbial alpha diversity, beta diversity, and abundance of microbial taxa between the steviol glycoside and sucrose beverage consuming groups will be evaluated as well as fecal SCFA concentration, fasting serum insulin, glucose and lipids, weight, BMI, pulse and blood pressure at weeks 0(baseline),4(study end) and 8(follow up).
