Intensive individualized nutritional counseling requires
nutrition professionals with specific experience in oncology. If
the patient is unable to achieve his or her nutritional requirements
via regular foods, nutritional supplements may be
prescribed, the composition of which is based on the dietary
deficits detected in the individual and detailed intake questionnaire.
Thus, any nutritional intervention must be based on the
need for an adequate intake and also must take into consideration
other relevant factors such as digestive and absorptive
capacity, the need for alleviation or arrest of symptoms, and any
psychological issues.
