Using Continuous Glucose Monitoring to Quantify the Effects of NOURISH's Culturally Modified Meals on Asian Americans With Type 2 Diabetes

Validation of NOURISH Project's Culturally Tailored Meals on Postprandial Glycemic Response Using Continuous Glucose Monitoring: A Quantitative and Qualitative Study

The investigators are hoping to determine whether tailoring the diet of someone with type 2 diabetes to their ethnic group while following American Diabetes Association guidelines can make a significant difference in their blood sugar controls. Participants will be required to wear a Continuous Glucose Monitor (CGM) for 1-month so that the investigators can compare blood sugar levels when participants are eating their routine diet vs. the culturally tailored diabetes diet.

This clinical trial evaluates the impact of culturally tailored, American Diabetes Association (ADA)-compliant meals on the glycemic control of Asian Indian and Filipino individuals with Type 2 Diabetes Mellitus (T2DM). This study leverages a crossover design to compare glycemic responses during two distinct dietary phases: a self-selected diet phase (baseline/control/routine diet) and an intervention phase featuring NOURISH meals. NOURISH Meals will be delivered to designated pick-up points on the Stanford campus and Stanford clinics. Participants will be equipped with Continuous Glucose Monitors (CGMs) to track glucose trends across the study and will be required to keep a food log through Tastermonial, enabling detailed analysis of postprandial glucose responses and key metrics.

Inclusion Criteria:

• Self-identification as Asian Indian or Filipino
• Diagnosed with T2DM
• Pick up and consume personally tailored cultural food and meal options for 1 week
• Willing to wear a CGM for 30 days

Exclusion Criteria:

• Currently taking insulin
• Known severe allergic reactions and/or food intolerances that would interfere with the ability to eat
• Those who, in the opinion of the investigators, cannot reliably complete the study protocol.
