Answer 1 is incorrect. 29% chose this answer, “A low-carbohydrate diet eating pattern of <26% of calories from carbohydrates can lead to a reduction in A1c.” Low-carbohydrate eating patterns (defined as <26% of calories from carbohydrates) have been shown to lower A1C in adults with type 2 diabetes and are supported by the 2025 ADA Standards of Care as one of several individualized eating patterns.

Answer 2 is correct. 50% of you chose this answer, “Nutrition therapy provided by a registered dietitian nutritionist (RDN) can result in A1C reductions of up to 0.5%.” The 2025 ADA Standards of Care state that medical nutrition therapy (MNT) provided by an RDN can lead to A1C reductions of 0.3% to 2%, especially in individuals with type 2 diabetes. The answer is not true because a 0.5% reduction underestimates the potential benefit.

Answer 3 is incorrect. About 11% of respondents chose this, “Individualized nutrition therapy should begin at diagnosis.” The ADA recommends that individualized MNT should be initiated at the time of diagnosis. Additional times for referral include annually or when not meeting treatment goals, when complications occur or when transitions in life occur. 

Finally, Answer 4 is incorrect. 8% chose this answer, “A Mediterranean eating pattern can reduce the risk of major cardiovascular disease events.” The Mediterranean eating pattern has been associated with improved glycemic control and a reduced risk of cardiovascular events, making it an eating pattern to consider for people with type 2 diabetes.
