|Nutrition for Cancer Survivors|
With treatment completed, you no doubt want to put cancer behind you and resume a more normal life. Now is the time to take charge of your health, focus on wellness, and swear off unhealthy habits, such as fast foods and a sedentary lifestyle. Research shows that the best formula for staving off another bout of cancer is proper nutrition combined with weight control and exercise.
Food and Recurrence
While there are many benefits to eating well, the data are mixed on whether diet alone can prevent certain cancers from returning. Nevertheless, there is strong evidence that a plant-based diet cuts the risk of cancer overall. Many epidemiologic studies have shown that people who eat diets rich in fruits and vegetables and sparse in meat and animal fat have lower rates of some cancers, including lung, breast, colon and stomach cancers.
The mechanisms at work are still being explored, but studies indicate that red meat promotes inflammation in human tissue; this inflammation is believed to stimulate the growth of cancerous tumors. Plant foods, on the other hand, contain antioxidants such as beta-carotene, lycopene, and vitamins A, C, and E, which protect the cells from free radicals - unstable molecules that damage healthy cells and are linked to aging and disease.
Phytochemicals, 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.
Weight and Recurrence
There is evidence that being overweight, which is a risk factor for numerous types of cancer, also increases the chance of recurrence and lowers odds for survival. Research has shown that women who gain more than 13 pounds during treatment for early-stage breast cancer are 1.5 times more likely to experience a cancer recurrence. Studies show that for men who have had prostate cancer, being overweight or obese raises the chances that their cancer will recur, spread, or lead to death.
What’s Best to Eat?
During cancer treatment, many people lose weight because chemotherapy and radiation side effects, such as nausea, taste changes and loss of appetite, make eating unpalatable; sometimes the therapy itself impairs the absorption of nutrients. Other people may put on pounds from medications, reduced activity, or emotional and stress-related eating. Consulting with a dietician may help you develop the best eating plan for your situation. Ask your doctor for a referral.

To Go or Not to Go Organic
Research on the nutritional benefits of organic fruits and vegetables has been mixed, and there have been no studies examining whether organic produce is better at preventing cancer or cancer recurrence than non-organic produce.
Stephanie Meyers, a senior clinical nutritionist at the Dana-Farber Cancer Center in Boston, tells her clients to buy whatever produce they like, and to rinse all fruits and vegetables thoroughly with clean water. Buying organic foods is a personal choice, Meyer says, and cancer survivors do themselves no harm by not choosing to go organic.
