An object of the present invention is to provide a blood glucose level increase response reducing agent which can lower the maximum blood glucose level after a meal even with a small amount of ingestion and can promptly lower the blood glucose level which has increased after a meal. Baked barley-derived -glucan can lower the maximum blood glucose level after meals even if ingested in a small amount of less than 3 g per serving, and can quickly reduce the blood glucose level increased after meals, and as a blood glucose level increase response reducing agent It is valid.本発明の目的は、少量の摂取でも、食後の最高血糖値を低下させ、更に食後に上昇した血糖値を速やかに低下させ得る血糖値上昇応答低減剤を提供することである。 焼成された大麦由来β-グルカンは、1食当たり3g未満という少量の摂取でも、食後の最高血糖値を低下させ、更に食後に上昇した血糖値を速やかに低減でき、血糖値上昇応答低減剤として有効である。
