Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Basic science and observational human studies suggest that high conentrations of circulating Advanced Glycation End-products (AGEs) may promote cognitive decline in older adults. The purpose of this pilot study is to test the methodology and feasibility of a dietary intervention to lower AGEs in elderly diabetics in order to lay the foundations for a future fully powered randomized clinical trial (RCT).To this end, the present study is focused on recruitment strategies, adherence to an innovative intervention in older adults and study methods. An exploratory aim will be the effect of the intervention on cognition and cerebral blood flow in order to obtain necessary data to estimate effect-size for a future fully-powered RCT.

Blinding Strategy

SINGLE

Outcome Assessors
The participants and study dietitian can not be blind to the assigned dietary intervention. However, the clinical testing and all data analysis are carried out blind to the intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Low AGEs diet

Participants randomized to this arm will receive active instruction on reducing dietary AGEs intake, in addition to standard of care dietary guidance for type 2 diabetes.
