Guidelines Address Diet, Exercise, and Weight Control for Cancer Survivors

New guidelines from the American Cancer Society recommend that people living with cancer maintain a healthy weight, get enough exercise, and eat a healthy diet. Increasingly, scientific evidence shows that healthy nutrition and physical activity behavior after a diagnosis can lower the chances of the cancer coming back, and can improve the chances of disease-free survival. The updated Nutrition and Physical Activity Guidelines for Cancer Survivors was published early online today in CA: A Cancer Journal for Clinicians.
Colleen Doyle MS RD, American Cancer Society director of nutrition and physical activity and co-author of the guidelines, said, “While we’ve published previous reports outlining the evidence on the impact of nutrition and physical activity on cancer recurrence and survival, this is the first time the evidence has been strong enough to release formal guidelines for survivorship, as we’ve done for cancer prevention. Living a physically active lifestyle and eating a healthy diet should absolutely be top of mind for anyone who’s been diagnosed with cancer. “
Doyle explains further on the American Cancer Society’s Expert Voices blog.
Among the recommendations:

1. Achieve and maintain a healthy weight.

  • Avoid weight gain during cancer treatment, whether you are at a healthy weight or overweight.
  • Weight loss after recovery from treatment may benefit survivors who are overweight or obese.

2. Be physically active.

  • Studies show that exercise is safe during cancer treatment, and can improve many aspects of health, including muscle strength, balance, fatigue, and depression.
  • Physical activity after diagnosis is linked to living longer and a reduced risk of the cancer returning among people living with cancer, including breast, colorectal, prostate, and ovarian cancer.

3. Eat a healthy diet, with an emphasis on fruits, vegetables, and whole grains.

  • The most health benefits are associated with a diet high in fruits, vegetables, whole grains, poultry, and fish, and low in refined grains, red meat and processed meat (such as hot dogs), desserts, high-fat dairy products and French fries. Most of the studies about cancer and diet have focused on breast cancer.
  • Studies show that taking vitamins, herbs and other nutritional supplements often does not help cancer patients live longer, and may even shorten life. Before taking any supplement, discuss it with your health care provider.
The recommendations also include specific guidance for people diagnosed with breast, colon, endometrial, ovarian, lung, prostate, head and neck, and blood cancers. It includes a section with answers to common questions about alcohol, organic foods, sugar, supplements, and several other areas of interest.
