The major goal of medical nutrition therapy for clients with diabetes mellitus is to:

A. Reduce serum lipid levels: While managing lipid levels is important for clients with diabetes, it is not the primary goal of medical nutrition therapy (MNT). The main focus is on blood glucose control rather than just lipid management. B. Maintain as near-normal a blood glucose level as possible: The primary goal of MNT for clients with diabetes mellitus is to achieve and maintain near-normal blood glucose levels to prevent complications such as retinopathy, neuropathy, and cardiovascular disease. C. Improve health through optimal nutrition: While optimal nutrition is important for overall health, the main objective of MNT in diabetes is focused on blood glucose control. Proper nutrition contributes to overall health, but it is not the sole goal. D. Wean insulin-dependent clients with diabetes from insulin through diet control: While diet control can help manage blood glucose, it is unlikely to completely eliminate the need for insulin in insulin-dependent clients with type 1 diabetes.
