The composition herein contains phosphatidylcholine which acts as a main component in a substrate gel. The composition can activate the brain through oral intake, and when being chewed, the composition has an oral adhesiveness lower than 200J/m<；3>；, has an oral compendency put at 0.1-1.0, and a surface area put at 5-85cm<；2>；.
