As in the test in Reference Example 1 , the blood glucose level of the group administered with the composition containing the composition containing the white sweet potato anti-diabetic component was not changed in normal rats as compared with the group not administered with normal rats.
Insulin levels increased significantly at P <0.01. Also,
In the glucose tolerance test, as shown in Tables 3 and 4 and FIGS. 1 and 2, the blood glucose level was significantly reduced at P <0.01 after 60 minutes of glucose load, compared with the non-administration group. Insulin levels are
There was a significant increase at P <0.01 before and after glucose loading. From these results, it is considered that the antidiabetic component contained in the white sweet potato does not affect the blood glucose level of normal rats, but has an action of promoting insulin secretion and suppressing an increase in blood glucose level during glucose load.

Reference Example 6 (Administration test of powdered composition of white sweet potato anti-diabetic component to humans) Ten diabetic patients who had been treated with tolbutamide [sulfonylurea (SU)] for non-insulin-dependent diabetes were treated. An administration test of a composition of the composition containing the white sweet potato anti-diabetic component was performed on a subject. In the test method, the oral administration of tolbutamide [sulfonylurea agent (SU agent)] was stopped, and instead, the powdered white potato antidiabetic component-containing composition powder obtained in Production Example 1 was 3 g once a day for 10 consecutive days. I took it inside. Before and at the start of the oral administration, the fasting blood glucose was measured to evaluate the effectiveness of the white sweet potato anti-diabetic component-containing composition powder. As a result, the fasting blood glucose level, which was 130 to 182 mg / dl in 10 patients before the start of the test, dropped to 83 to 143 mg / dl at the end of the test. In addition, the body fatigue, ease of fatigue, and the like were also substantially eliminated in eight subjects, confirming the effectiveness of the composition containing the composition of the white potato anti-diabetic component for diabetes in humans.

Thereafter, the value significantly decreased at P <0.05, and in the insulin secretagogue test, the insulin value significantly increased at P <0.01. From this, it is considered that the antidiabetic component contained in the white sweet potato (the skin portion of which is freeze-dried) has an action of promoting insulin secretion and an action of suppressing an increase in the blood glucose level of diabetic rats during glucose load. .

The food composition containing an antidiabetic component of the present invention has an antidiabetic effect. That is, the antidiabetic component-containing food composition of the present invention has an excellent insulin secretion promoting action, can suppress an increase in blood glucose level after a glucose tolerance test, and has an excellent glucose tolerance improving action. Things. Next, the method of taking the anti-diabetic component-containing food composition of the present invention is not limited because the food composition does not lower the blood sugar level to a normal value or lower and does not cause side effects such as hypoglycemia. In addition, an effect of improving hyperlipidemia, which is a complication of diabetes, was also observed. Furthermore, the anti-diabetic component-containing food composition of the present invention can be obtained at a high concentration from the skin portion of naturally produced white sweet potato. Therefore, the anti-diabetic component-containing food composition of the present invention can be safely and easily ingested as a food composition having an insulin secretagogue-promoting action and a glucose tolerance-improving action, and is useful for diabetic patients and their reserves. It can be used effectively.
