The investigators will investigate the tastes (umami, bitter, salty, sweet and sour) that the patients prefers in order to increase the energy intake and reduce the risk of weight loss and loss of fat-free mass for patients with hematological cancer.~The study will be conducted as a single blinded randomized controlled trial. 40 patients will be recruited, and will be divided into two groups; the intervention group and the control group. The patients will not know which group they belong to.
The purpose of the study is to investigate whether a simple taste-test will increase the intake of energy as part of the individual dietary counseling.
