According to a recently published study, Nutrients We explore the challenges and opportunities of technology in managing type 1 diabetes (T1D) through nutrition reporting. The study highlights that people with T1D (PwT1D) are willing to use technology if it offers meaningful benefits, such as improved time in range (TIR).1

This study conducted an online survey aimed at understanding current practices and preferences regarding carbohydrate estimation, nutrient tracking, and attitudes towards technology among people with PwT1D and their caregivers. The survey also included hypothetical scenarios to gather personal preferences regarding technology use. The study noted that striking a balance between minimal user input and meaningful data output is key to accurate blood glucose (BG) management without burdening the user. However, individual personalities and preferences have proven challenging to develop a universally effective solution for the application.2
The study used a cross-sectional, single-center design, and participants were recruited through social media groups specifically targeted at PwT1D. The questionnaire collected responses from 39 participants, 33 people diagnosed with T1D, and six caregivers between August 2022 and November 2023. Mean hemoglobin A1C This accounted for 6.8% (1.6%) of participants.
Consistent with other studies, the findings of this study indicate that carbohydrate counting is a major challenge for PwT1D and errors in estimation lead to fluctuations in glycemic control.3 Participants estimated carbohydrates in a variety of ways, including reading the nutrition facts label (37%), estimating visually (48%), and using tools such as Carbs and Cals, a visual reference guide available online (18%).Four
The authors state that “the error rate in carbohydrate estimation varies depending on individual skill, food complexity, and measurement accuracy but is estimated to be 25%, which directly impacts glycemic control and ultimately the time spent within the target glycemic range of 3.9-10 mmol/L TIR.” Improving TIR was identified as a strong motivator for technology use, with 89% of respondents saying they would engage more with technology if it promised to increase TIR. Furthermore, 78% indicated a willingness to adjust their insulin dose based on the app’s suggestions to optimize TIR.
Respondents varied in their nutrition reporting preferences. Half of participants preferred a “type and scroll” method, either manually entering foods or selecting from a pre-loaded list. Around 30% preferred taking photos of their meals, and 15% preferred talking to a virtual assistant. A minority (5%) said they did not prefer reporting. The timing of reporting nutrition intake also varied, with 55% of respondents preferring to report after meals, 33% before meals, and 12% preferring to report later, such as at the end of the day.
Use of nutrition reporting apps was mixed. Around 16% of respondents used apps regularly, while 34% said they initially used the apps but then stopped using them. 28% of respondents used apps for a specific purpose, and 22% had never used them. Responses regarding the level of detail in nutrition reporting varied. Most people used a single word (e.g., pizza) or a simple description (Sunday dinner). Only 8% used a detailed description of the meal, and 30% of participants used quantifiers such as portions or weights.
“The need for self-management requires PwT1D patients to make an additional 180 decisions each day to regulate their blood glucose levels, and diabetes-related technologies and apps have emerged as a valuable resource to ease this burden,” the researchers wrote. When asked about the burden of nutrition reporting, 36% considered it “stressful but manageable,” 11% a “total nightmare,” and just 7% easy. The majority, 46%, “didn’t feel strongly either way” about carbohydrate counting.
Although challenging, the authors point out the importance of developing technology that seamlessly integrates into everyday life.
“Going forward, this study will provide valuable insights to aid in the development of environmentally friendly tools aimed at improving the experience of managing type 1 diabetes, envisioning a future characterized by personalized, precise and convenient care.”
