PROBLEM TO BE SOLVED: To provide a hydrogen-generating food product, which achieves stable and persistent supply of hydrogen.SOLUTION: The hydrogen-generating food product includes: a first hydrogen-generating material which reacts with water to generate hydrogen, and a second hydrogen-generating material which generates hydrogen by fermentation. After oral ingestion, the hydrogen-generating food product causes the first hydrogen-generating material to react with water component in the digestive organ of a human body for generation of hydrogen, and causes the second hydrogen-generating material to generate hydrogen by fermentation in the large bowel, thus achieving stable and persistent supply of hydrogen.COPYRIGHT: (C)2015,JPO&INPIT【課題】 安定的且つ持続的な水素供給を達成する水素発生食品の提供。【解決手段】 水と反応し水素を発生させる第一水素発生物質と、発酵により水素を発生させる第二水素発生物質とを含有し、経口摂取後、人体の消化器官内の水分で上記第一水素発生物質による水素発生を促すと共に大腸内発酵で上記第二水素発生物質による水素発生を促し、安定的且つ持続的な水素供給を行う水素発生食品を提供する。【選択図】 図1
