Consumption of oral hospital diets and percent adequacy of minerals in oncology patients as an indicative for the use of oral supplements.

Abstract

Background & aims: Deficiencies in the consumption of foods and nutrients favor malnutrition in patients. Considering the recommendations for the ingestion of minerals, the content, consumption and percent adequacy of the minerals (Ca, Cu, Fe, Mg, Mn, K, P, Na, Zn and Se) were evaluated amongst oncology patients who received oral diets isolated or associated with an oral food complement (OFC), evaluating the need and composition of an oral supplement. Methods: The mineral composition as determined by ICP-OES, and the food consumption of the patients served regular, bland and soft diets, were evaluated on six non-consecutive weekdays. Patients with increased nutritional needs received OFC. The consumptions were calculated by deducting the weight of the leftovers from the value served. Results: A total of 163 patients took part of which 59.5% were men, the mean age was 57 _ 15 years old, and 126 (77.3%), 27 (16.6%) and 10 (6.1%) were served the regular, bland and soft diets, respectively, with (23.0%), 8 (30.7%) and 4 (40.0%) receiving the OFC. Patient consumption was lower when the regular (74.2 vs 79.7%) and soft (68.9 vs 74.2%) diets were combined with OFC. For all diets, less was consumed at the lunch (61.2%e65.7%) and dinner (39.9%e62.8%) meals. Patients that received the OFC showed reduced meal consumption and higher Ca ingestion. The mineral contents of the diets were inadequate, with 66.8% of the patients ingesting Na above the UL and K below the nutritional recommendation (100%). Conclusion: The diet consumption, isolated or associated with OFC was insufficient, and hence the exclusion of OFC and the inclusion of a mineral supplement (without P and Na) was indicated to adequate ingestion to the nutritional recommendations.
