ACTIVE NOT RECRUITING

NCT05441982

Saccharin and Acesulfame Potassium Consumption and Glucose Homeostasis in Older Adults With Prediabetes

Animal and observational research in humans suggest that specific types of non-nutritive sweeteners (NNS) may impair glycemic control. However, whether NNS consumption impacts glucose homeostasis in middle-aged/older adults with prediabetes is unknown, and potential mechanisms by which this could occur have yet to be identified. The overall objective of this R21 proposal is to establish proof-of-concept for alterations in glucose homeostasis following intake of saccharin, but not acesulfame potassium, in middle-aged/older adults with prediabetes compared to a eucaloric diet with no NNS.

Non-Nutritive Sweetener Consumption and Glucose Homeostasis in Older Adults With Prediabetes

Animal and observational research in humans suggest that specific types of non-nutritive sweeteners (NNS) may impair glycemic control. However, whether NNS consumption impacts glucose homeostasis in middle-aged/older adults with prediabetes is unknown, and potential mechanisms by which this could occur have yet to be identified. The overall objective of this R21 proposal is to establish proof-of-concept for alterations in glucose homeostasis following intake of sucralose, but not aspartame, in middle-aged/older adults with prediabetes compared to a eucaloric diet with no NNS.
