Reduced food intake is a common problem in patients with malignant disease. Oral supplements can be easily added to foods to increase their nutrient-energy content. In a previous study (Parkinson et al., 1987), Polycal was found to be the most acceptable energy supplement although it did not increase the energy content as much as had been hoped. Duocal, a relatively new product, was not then tested. It has a higher energy density, so might be expected to give a greater increase at the same level of palatability. This study was set up to compare the palatability and ability to increase energy of Polycal and Duocal, when incorporated into commonly used recipes. The first stage assessed the relative palatability of the two energy supplements, and found them to be equal. The second stage then set out to find the maximum acceptable amount of Duocal which could be added to a recipe. It was found that Duocal could make a larger contribution to increasing the energy content of the diet than Polycal.
