title: Dietary fiber intakes of nursing home residents and independent-living older adults.
abstract: Daily dietary fiber intakes were determined for two groups of older adults with significantly different bowel habits: nursing-home (NH) residents who habitually took laxatives and independent-living (IL) adults who took laxatives occasionally. Fiber intakes were calculated from neutral detergent fiber (NDF) and Southgate total dietary fiber values. IL subjects (n = 7) consumed on average 9.0 +/- 1.6 g NDF and 18.8 +/- 4.6 g total fiber daily. The NH menu provided a similar amount of NDF but more total fiber. NH residents (n = 6) consumed approximately 70-85% of the fiber served. When fiber intakes were expressed as energy, NH and IL subjects consumed similar amounts of NDF but IL subjects consumed less total fiber. Grain products were major fiber sources for both groups; IL subjects consumed more fiber from fruits. Comparisons of fiber intakes, bowel function, lifestyles, and medications suggest that dietary fiber is only part of the basis for inadequate large bowel function experienced by some elderly populations.
