There are many treatment side effects that can affect your food intake and your appetite. A lot of time can be spent travelling to the hospital, waiting around for appointments and staying in temporary accommodation with limited cooking facilities. Having a range of quick and easy snacks that are suitable to eat when you're away from home, or when you don't feel like preparing a meal is important to prevent weight loss and malnutrition.
If you're not able to eat your usual amount of food, or you need to gain or maintain your weight, it's helpful to take in more energy (kilojoules) without having to eat more. Try adding extras to your basic foods at mealtimes, such as protein, fats and sugar.
Increasing the amount of energy or kilojoules (e.g. protein, fat and sugar) in your diet is usually a temporary measure to keep you eating well during and after treatment. It's important to understand that eating extra fat and sugar while you're underweight, or struggling to maintain your weight because of treatment side effects won't hurt you and is often only needed for a small period of time.
Speak with your doctor and dietitian about relaxing low-cholesterol or diabetes dietary restrictions that may prevent you from eating extra fat and sugar.
If you can't manage to eat a balanced and varied diet, or are experiencing unintentional weight loss, then it's recommended that you use nourishing fluids and/or nutritional supplements.
Nutritional supplements such as Sustagen Hospital Formula, Ensure and Resource contain energy, protein and other nutrients in a concentrated source. Glucose powder supplements can also provide energy, but they don't provide protein, vitamins or minerals, so they have a particular function and shouldn't be used as a meal replacement. You can sprinkle glucose powder on food or stir it through to give meals and snacks extra energy.
Nutritional supplements and/or nourishing fluids should be taken in addition to eating your usual meals, for example try them as between meal snacks. A dietitian can suggest the most appropriate supplement for you, and where it can be purchased. Your choice of supplement should be based on your nutritional needs, on availability and on the cost of the supplement.
If you've been assessed by a speech pathologist as having swallowing difficulties and need thickened fluids the nutritional supplements need to be thickened to the advised consistency. Discuss this with your speech pathologist.
The following tables provide some suggestions of nutritional supplements which you may be able to try (however it shouldn't be considered a complete list of those available).

Vitamins and minerals are an essential part of a healthy diet and play an important role in the body’s immune system. If you're managing to eat a balanced diet through eating a variety of foods then the use of vitamin and mineral supplements isn't usually necessary.
Some people believe that taking high–dose vitamin supplements will strengthen the body’s immune system, but there's little evidence to support this. In fact, many vitamins and herb compounds can be toxic at high levels, and may interfere with chemotherapy, radiotherapy and other medications. Therefore high doses of vitamin or mineral supplements are usually not recommended for use during treatment.
Dietary supplements can't replace whole foods, which are still the best source of vitamins and minerals. Many dietary supplements contain levels of antioxidants (such as vitamins C and E) that are much higher than the recommended Dietary Reference Intakes for optimal health.
Whether antioxidants or other vitamin supplements are helpful or harmful during chemotherapy or radiation treatment is a major question without a clear science–based answer right now. Until more evidence is available, it’s best for people having these treatments to avoid dietary supplements, except to treat a known deficiency of a certain nutrient, and to avoid supplements that exceed the recommended daily intake.
Talking to your doctor, dietitian or cancer pharmacist before taking vitamin and mineral supplements or before starting treatment is encouraged. For more information, call Cancer Council on 13 11 20.
Complementary therapies are treatments that may help you cope better with side effects such as pain. They may also increase your sense of control over what's happening to you, decrease your stress and anxiety, and improve your mood. There are many types of complementary therapies, such as herbal medicine, acupuncture, massage, relaxation and meditation.
By contrast, alternative therapies, which include unproven diets, are often defined as those used instead of conventional medical treatments. These therapies may be harmful if people with cancer delay or stop using medical treatment in favour of them.
There are no special foods, diets or vitamin and mineral supplements that have been scientifically proven to cure cancer or to stop it from recurring. Unproven diets are often expensive, restrictive and repetitive. It's important to enjoy a wide variety of foods to keep you well nourished.
Many unproven dietary treatments, particularly those that cut out food groups such as meat or dairy products are likely to be low in energy (kilojoules), protein, fat, iron, calcium and zinc as well as vitamins. This can cause unwanted weight loss, tiredness and decrease your immune function. Your recovery and quality of life can improve if your diet includes adequate amounts from each food group.
Some alternative therapies can be harmful even when used in combination with conventional therapy. It's important that your doctor, dietitian, nurses and pharmacist are aware of all the treatments you're taking.
For more information, see our Understanding Complementary Therapies pages, or call Cancer Council on 13 11 20.
Juice therapies involve using fresh fruit and vegetable juices as the main source of food. Supporters of juice therapy believe it strengthens the immune system, reduces blood pressure and helps to clean out (detoxify) the body.
However, while the health benefits of fruit and vegetables are well documented, the benefits of juice therapy are not. Juice only contains a fraction of the fibre of whole fruit or vegetables. The protective effect of fruit and vegetables may be related to many factors in the whole fruit and vegetables, not just the juice. Use fresh fruit and vegetable juices as part of a varied eating plan.
The questions below will help you assess any diet therapy you're thinking of undertaking. Is the diet likely to:
If you answer yes to any of these questions, the diet could affect your recovery and compromise your health. Some eating patterns and nutrition supplements or pills can be harmful and may interfere with the success of your medical treatment. Before radically changing the foods you eat, or taking vitamin/mineral pills or herbal remedies talk to your doctor or dietitian.
