Assessment
Primary outcomes 1. The measured value of fasting blood glucose level at 12 weeks after the start of test-food consumption (12w)
Key secondary outcomes 1. The ratio of the number of subjects who are less than 110 mg/dL in fasting blood glucose level at 12w

2. The measured value of fasting blood glucose level at eight weeks after the start of test-food consumption (8w)

3. The measured value of fasting blood glucose level at four weeks after the start of test-food consumption (4w)

4. The change values of fasting blood glucose levels between at the examination before start of test-food consumption and at 4w, 8w and 12w

5. IAUC0-30, IAUC0-60, IAUC0-90, IAUC0-120 and Cmax at the examination before test-food consumption (with glucose load)

6. The measured values of blood glucose levels at 30, 60, 90 and 120 minutes after glucose load of the examination before test-food consumption (with glucose load)

7. The change values of blood glucose levels before glucose load and at 30, 60, 90 and 120 minutes after glucose load of the examination before test-food consumption (with glucose load)

8-1. The measured values of hemoglobin A1c (HbA1c: NGSP) level at 12w
8-2. The change values of hemoglobin A1c (HbA1c: NGSP) level between at the examination before start of test-food consumption and at 12w
