Diet therapy is a standard treatment for diabetes mellitus, but patients and their families find it difficult to cook the required food at home. The use of food delivery for diabetes treatment is spreading, so we evaluate the system for patients with diabetes mellitus. Twelve outpatients used the system for 3 months. Energy intake, HbA
1c, total cholesterol, triglyceride, albumin, and quality of life (QOL) were measured before and after system use. QOL was evaluated by the Problem Areas in Diabetes (PAID) score. Energy intake before this study was 1841kcal/day. After three months of using the system, energy intake decreased significantly to 1640kcal/day (p<0.05). Based on the low energy intake, HbA
1c improve from 7.2% to 7.0%(p=0.079) and triglyceride decreased significantly from 201.7 mg/d
l to 158.8mg/d
l (p<0.05). The PAID score did not change before and after this study. Food delivery is thus thought to be useful for patients with diabetes mellitus who can neither understand their own nutritional requirements nor cook a recommended diet property.
