Nutritional effects of supplementing liquid-formula diet with dietary fiber on elderly bed-ridden patients.

In the past few decades, the number of bed-ridden elderly patients has been increasing. This group of patients is frequently fed with a liquid formula diet. The aim of this study was to evaluate the usefulness of a liquid formula diet containing dietary fiber (DF) for elderly bed-ridden patients.

Protective effects of (-)-epigallocatechin gallate and (+)-catechin on paraquat-induced genotoxicity in cultured cells.

The protective effects of green tea polyphenols on paraquat-induced genotoxicity in cultured cells were studied. (-)-Epigallocatechin gallate (EGCG), the major constituent of green tea, and (+)-catechin (CT), a minor constituent, equivalently decreased the frequencies of sister-chromatid exchanges (SCE) induced by paraquat (PQ), which is a generator of reactive oxygen species. These polyphenols were effective at concentrations of 1.
