It has been confirmed in tests in human that 1-kestose has an effect of increasing the production of an immunoglobulin A (IgA) antibody, an effect of inhibiting the production of an immunoglobulin E (IgE) antibody, an effect of activating the growth of an enteral Bifidobacterium (intestinal Bifidobacterium) and an effect of ameliorating atopic dermatitis in infants and young children. Based on this finding, there are provided an allergy-suppressive composition, an allergy-suppressive food and an allergy-suppressive agent comprising 1-kestose. Since 1-kestose has the effect of increasing the production of an IgA antibody, the effect of inhibiting the production of an IgE antibody and the effect of activating the growth of an intestinal Bifidobacterium, the composition, food and agent comprise 1-kestose as the active ingredient and are effective for the prevention of the development and effective for the treatment of an condition of allergic diseases including atopic dermatitis in infants and young children.
