ABSTRACT 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. Eighteen elderly, bed-ridden patients were given L-3 Fiber, a DF-containing liquid formula diet (DF-LFD), for 4 weeks, while a number of parameters were monitored, including serum levels of total cholesterol, triglyceride, total protein, creatinine, uric acid, glucose, sodium, potassium, and calcium, urine protein/sugar, and defecation frequency. Total protein, albumin and total cholesterol significantly increased following the administration of the DF-LFD, associated with an average increase in body weight of 1.94 kg (5.0%). Defecation frequency significantly increased one week after DF-LFD administration was started, but this effect was transient. Although a few patients complained of nausea, vomiting or abdominal pain, no severe side effects were seen. In conclusion, DF-LFD supplementation appears to be beneficial for elderly bed-ridden patients, and can increase nutritional-related parameters, such as body weight, total protein, albumin and total cholesterol, without severe side effects.

    ABSTRACT: Enteral diets based on conventional foods are used in domestic nutritional therapy to provide macronutrients, obtain individualised diets and to lower costs. Eggplant, carrot, chicory, lettuce, guava and tamarind were studied as sources of soluble and insoluble fibers for use in enteral diets or as oral nutritional supplements, added to a domestic enteral formulation and also prepared in aqueous solution. The following physical-chemical characteristics were determined: soluble and insoluble fibers, proximate composition, pH and water activity. Drip tests were carried out with the formulas containing the experimental foods and as an oral nutritional supplement the best proportion of food/water was shown to be 150 g/2 L, whereas when added to the formula, the best proportion was 100 g food/2 L of formula. The amounts of each food added to the enteral formula were equivalent to two daily portions (100 g) of each food per 2 L or 2000 kcal. Of the foods tested, the guava contributed the greatest amount of fiber and the eggplant the least. The values for water activity were between 0.95 and 1.00, indicating that these diets should be consumed immediately after preparation.
