Fibe Mini (ファイブミニ) is a Japanese soft drink with added dietary fiber produced by Otsuka Pharmaceutical. It was launched in 1988, and is often considered the first "functional food".
The functional ingredient is polydextrose,[1][2][3][4][5] which has been associated with health benefits.[6] The drink also includes minerals and vitamins.[7]
It was a hit upon launch and began the functional food trend in Japan from 1988 to 1989, a period that produced 51 dietary fiber drinks.[8] The fiber sources of these products were often added to milk and soft drinks.[6]
