Food – not supplements – are the best source of vitamins and minerals. There is no evidence that dietary supplements provide the same anti-cancer benefits as fruits and vegetables, and some high-dose supplements may actually increase cancer risk. www.nccn.org; 2018
Here are some general nutrition recommendations for people receiving cancer treatment:
Maintain a healthy weight. For many people, this means avoiding weight loss by getting enough calories every day. For people who are obese, this may mean losing weight. Ask your health care team if it is okay to try to lose weight during treatment. It may be better to wait until after treatment ends. If it is okay, weight loss should be moderate, meaning only about a pound a week.
Get essential nutrients. These include protein, carbohydrates, fats, and water.
Be as active as you can. For example, take a daily walk. If you sit or sleep too much, you may lose muscle mass and increase your body fat, even if you are not gaining weight.
Patients who maintain good nutrition during cancer treatments are more likely to tolerate the side effects. Adequate calories and protein can help maintain patient strength and prevent body tissues from further catabolism.
Phytochemical’s, also found in fruits, vegetables, legumes and grains, are compounds that may thwart the action of carcinogens (cancer-causing substances) and aid cells in blocking the development of cancer.
