Currently, there is no consensus about how to best treat malnutrition in elderly long-term care residents. A recent study found that the traditional treatment method of serving small, frequent meals was not effective at increasing energy intake. This review describes strategies to treat malnutrition in this vulnerable population.
PURPOSE Texture-modified diets offered in long-term care (LTC) facilities are often prepared from the regular menu, planned using Canada's Food Guide to Healthy Eating. The appropriateness of protein levels of puréed diets in LTC facilities was determined. METHODS Protein content was measured in 29 duplicate diets, collected from 20 urban LTC facilities(More)
Green lentils are an increasingly popular food, but their effects on human colonic function and serum lipids have been studied little. Nine healthy males aged 19-38 y consumed for 3-wk periods a controlled Western diet and the same diet supplemented with 130 g dry lentils/d [which contained 11.8 g non-starch polysaccharide (NSP)] incorporated into loaves,(More)
The intake of whole-grain (WG) foods by adolescents is reported to be approximately one-third the recommended intake of 48 g/d. This 6-wk randomized interventional study determined the effect of replacing grains within the diet with refined-grain (RG; n = 42) or WG (n = 41) foods/d on gastrointestinal and immune health in adolescents (aged 12.7 ± 0.1 y).

Pulses, including peas, have long been important components of the human diet due to their content of starch, protein and other nutrients. More recently, the health benefits other than nutrition associated with pulse consumption have attracted much interest. The focus of the present review paper is the demonstrated and potential health benefits associated(More)
Prebiotic and probiotic therapies are new strategies being used to treat gastrointestinal diseases. Recent evidence suggests that the administration of select prebiotics and probiotics, alone or in combination (the latter called "synbiotic" therapy) may improve the clinical outcome of patients with ulcerative colitis. We report a case of a pediatric(More)
OBJECTIVE To determine the effects of supplemental fiber on plasma p-cresol, stool frequency, and quality of life (QoL) in chronic kidney disease (CKD) patients. DESIGN AND SETTING In a 12-week single-blind study, participants were provided with control muffins and supplements (5.5 g sucrose/day) for 2 weeks, muffins containing 10 g/day pea hull fiber and(More)
Actinobacteria, particularly bifidobacteria, are widely observed to be underrepresented in metagenomic studies of microbial communities. We have compared human fecal microbiota clone libraries based on 16S rRNA and cpn60 PCR products. Taxonomic profiles were similar except that the cpn60 libraries contained large numbers of bifidobacterial sequences.
BACKGROUND Acute psychological stress induced by academic exams is associated with dysregulated gastrointestinal and immune function. OBJECTIVE We examined whether supplementation with galactooligosaccharides reduced gastrointestinal dysfunction and the percentage of days with cold or flu in academically stressed undergraduate students. DESIGN In a(More)
OBJECTIVES We wanted to develop thickened beverages that contain soluble fiber (inulin) with acceptable consistency, taste, and texture and to determine the effects of these beverages on bone resorption markers (to determine calcium retention), bowel frequency, and indicators of gastrointestinal function in institutionalized adults bound to wheelchairs.
