Key Features of ResoluCan™ Nutritional Support
What Is Cancer Nutritional Support?
According to the National Cancer Institute, nutrition in cancer care embodies prevention of disease, treatment, cure, or supportive palliation. Caution should be exercised when considering alternative or unproven nutritional therapies during all phases of cancer treatment and supportive palliation, as these diets may prove harmful. Patient nutritional status plays an integral role in determiningb not only risk of developing cancer but also risk of therapy-related toxicity and medical outcomes. Whether the goal of cancer treatment is cure or palliation, early detection of nutritional problems and prompt intervention are essential.
The original principles of nutrition care for people diagnosed with cancer were developed in 1979  and are still very relevant today. Proactive nutritional care can prevent or reduce the complications typically associated with the treatment of cancer.
Many nutritional problems stem from local effects of the tumor. Tumors in the gastrointestinal tract, for example, can cause obstruction, nausea, vomiting, impaired digestion, and/or malabsorption. In addition to the effects of the tumor, marked alterations in normal metabolism of carbohydrates, protein, and/or fats can occur.
The nutritional prognostic indicators most recognized as being predictive of poor outcome include weight loss, wasting, and malnutrition. In addition, significant weight loss at the time of diagnosis has been associated with decreased survival and reduced response to surgery, radiation therapy, and/or chemotherapy.
Malnutrition and accompanying weight loss can be part of an individual’s presentation or can be caused or aggravated by treatments for the disease. Identification of nutrition problems and treatment of nutrition-related symptoms have been shown to stabilize or reverse weight loss in 50% to 88% of oncology patients.

What Is the Goal of Nutrition Therapy in Cancer?
Optimal nutritional status is an important goal in the management of individuals diagnosed with cancer. Although nutrition therapy recommendations may vary throughout the continuum of care, maintenance of adequate intake is important. Therefore, a waiver from most dietary restrictions observed during religious holidays is granted for those undergoing active treatment. Individuals with cancer are encouraged to speak to their religious leaders regarding this matter before a holiday.
Whether patients are undergoing active therapy, recovering from cancer therapy, or in remission and striving to avoid cancer recurrence, the benefit of optimal caloric and nutrient intake is well documented.[1-3] The goals of nutrition therapy are to accomplish the following:
1) Prevent or reverse nutrient deficiencies. 2) Preserve lean body mass. 3)Help patients better tolerate treatments.
4) Minimize nutrition-related side effects and complications. 5)Maintain strength and energy. 6) Aid in recovery and healing.
7) Protect immune function, decreasing the risk of infection. 8) Maximize quality of life.
Patients with advanced cancer can receive nutritional support even when nutrition therapy can do little for weight gain.[4-5]
Such support may help accomplish the following:
1) Lessen side effects. 2) Reduce risk of infection (if given externally). 3) Reduce asthenia. 4) Improve well-being.
In individuals with advanced cancer, the goal of nutrition therapy should not be weight gain or reversal of malnutrition, but rather comfort and symptom relief.(6)]
Nutrition continues to play an integral role for individuals whose cancer has been cured or who are in remission.[7 ] A healthy diet helps prevent or control comorbidities such as heart disease, diabetes, and hypertension. Following a healthful nutrition program might help prevent another malignancy from developing.
