PROBLEM TO BE SOLVED: To provide a new method for utilizing a far infrared radiation substance of good health promotion effect for the purpose of enhancing immune strength by allowing a substance radiating far infrared rays without containing heavy metal and radioactivity harmful to human bodies and animals, to reach a digestive organ orally to apply the far infrared rays to digestive organ cells in the digestive organ in order to allow far infrared rays effective on the living bodies, to act most effectively on the human bodies and other animals.SOLUTION: Fine powder of the substance having a far infrared radiation function but not digested nor absorbed in a digestive organ of a human body is packed in granules, tablets or capsules or suspended in a lactic acid bacteria beverage, soft drinks including tea or potable water, or mixed into processed food for oral drinking and eating to pass through a digestive canal. The far infrared rays are thereby radiated to the digestive organ cells when passing through the digestive organ to serve as an aid to health promotion.COPYRIGHT: (C)2012,JPO&INPIT【課題】生物体に有効な遠赤外線を人体、他の動物に対し最も有効に作用させるため、人体及び動物に対し有害な重金属や放射能を有する物質を含まず、遠赤外線を放射する物質を、経口にて消化器へ至らしめ、消化器官内において消化器官細胞へ遠赤外線を当て、免疫力を高めることを目的とした、健康増進効果のよい遠赤外線放射物質の新しい利用方法を提示すること。【解決手段】遠赤外線放射機能を有し、人体の消化器官で消化、吸収されない物質の微細粉を、顆粒、錠剤、カプセルに詰め、あるいは乳酸菌飲料、お茶を含む清涼飲料水、飲料水に懸濁させ、又は加工食品に混入介在させ、経口飲用、食用することにより消化管を通過させることにより、消化器官通過時に消化器細胞に遠赤外線を放射せしめ、健康増進の一助とさせる。【選択図】なし
