Why is Nutrition Important for Cancer Survivors?

People often finish cancer treatment and ask themselves the question – now what? After many months of different treatments and appointments it is time to take charge of the next phase of your journey. You may also feel different now that you have more time to focus on your well-being. While exciting, this can also cause a mix of emotions. The good news is nutrition can help you to take control of your health. Good nutrition is an important part of your care beyond cancer treatment.

Nutrition helps with:

  • Recovery and healing 
  • Regainning strength and weight 
  • Manage ongoing side effects 
  • Reduce risk of a future cancer diagnosis and keep you healthy 
  • Mainting a healthy weight 

Essentials of a Health Lifestyle after Cancer

Eating healthy after cancer treatment does not have to be overwhelming. You can start by making small changes. As you build small changes to how you eat into your routine, they will become part of your lifestyle. One useful starting point is to learn and follow nutrition guidelines. The American Institute for Cancer Research (AICR) has created simple, clear recommendations for cancer prevention. These recommendations are based on what scientific research has shown us about how nutrition and a healthy lifestyle can help prevent cancer and cancer recurrence.

1. Keep Your Weight Within A Healthy Range. Avoid Weight Gain In Adult Life.

A good guide is to keep your weight within a healthy range (BMI between 18.5 and 25). Click here for a BMI calculator. Achieving and maintaining a healthy weight is one of the most important things that you can do. Twelve cancers studied by AICR are linked to having weight above normal levels and obesity. Too much body weight typically indicates a higher amount of body fat. Higher amounts of body fat can create a more cancer friendly environment. It can release chemicals that can make cancer cells grow more easily.

2. Be physically active in your everyday life. Walk more and sit less.

It is important to include more movement in your daily routine. It is recommended that you do at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity per week. Even simple exercises like walking, gardening, yoga, or housework can help you achieve your goals. Exercise helps you manage weight and reduces hormone levels that may promote cancer growth.

3. Eat a diet rich in whole grains, vegetables, fruits, and beans.

Plant foods like whole grains, vegetables, fruits, and beans have many healthy ingredients that can help prevent cancer. They are rich in dietary fiber, vitamins, minerals, and phytonutrients. These foods are also naturally low in calories to help you maintain a healthy weight. It is helpful to eat a variety of colorful plant foods. Nuts and seeds are also part of a healthy plant-filled diet. Visit our recipe page for ideas.

4. Limit “fast foods” and other processed foods high in fat, starches, or sugars.

Limiting these foods helps control calorie intake and maintain a healthy weight. These processed foods are typically high in calories. Eating too many of these foods can lead to weight gain, becoming overweight or obese.

5. Limit red meats and avoid processed meats.

Red meats include beef, pork, and lamb. It is recommended you eat no more than 12 to 18 ounces per week for the prevention of colon cancer. Processed meats include ham, sausage, bacon, salami, and hot dogs. It is best to avoid these since even small amounts can increase cancer risk.

6. Limit sugar-sweetened drinks.

Drink mostly water and unsweetened drinks. Sugar sweetened drinks are not healthy and usually provide unneeded calories without added nutrition. Drinking too many unneeded calories from sugar-sweetened beverages can cause weight gain.

7. Limit alcohol.

For cancer prevention, it’s best not to drink alcohol. Alcohol in any form – beer, wine, or liquor – has been linked to 6 different cancers. Those who choose to consume alcohol should limit these beverages to no more than 1 drink per day for a woman and 2 drinks per day for a man.

8. Do not use supplements for cancer prevention.

A healthy diet rich in colorful fruits, vegetables, grains, beans, and lean protein is the best way to get nutrition. If you think that you are unable to meet your nutritional needs with diet alone, talk with your health care team before trying any new over-the-counter supplement.

Creating a Survivorship Plan

Being a cancer survivor can be overwhelming because for the first time in a long time, you can take charge of your health. It is time for you to take back control. A healthy lifestyle that includes nutritious foods and physical activity is a great way to take control of your health. Work with your health care team to make a plan that is right for you.

Start with small changes and set a goal to keep yourself on track. A good rule of thumb to remember is to make your goals S.M.A.R.T.

  • S - set SPECIFIC goals becuase general goals are much harder to achieve. For example, instead of “I will go to the gym” try “I will go to the gym 2 days during the week and one day on the weekend.”
  • M - set MEASURABLE goals since goals are easier to work on when you have something to work toward. Instead of saying “I will eat more fruits and vegetables” try “I will eat 5 different fruits and vegetables each day.”
  • A - set ATTAINABLE goals that make sense for you and your current lifestyle. Don’t be afraid to be bold and try something new. For example, “try one new recipe each week” might be an attainable goal for you since you have the energy and enjoy cooking. If you don’t like to cook, try a new smoothie instead. Smoothies can be made easily in a blender.
  • R - set REALISTIC goals that are doable for you at this stage in your cancer journey. If you’ve just completed treatment and are still dealing with some ongoing side effects like fatigue, cooking a healthy dinner from scratch every night might not be a realistic goal. Instead make one recipe, like marinated grilled chicken breast, that can be repurposed in meals throughout the week.
  • T - set TIMELY goals that have a time frame to help you stay on track. For example, for those who often skip meals, it might be helpful to set certain times of the day to eat breakfast, lunch, and dinner. Eating regular meals will help you avoid excess hunger and overeating.

Use the checklist below to set your own goals and apply what you’ve learned. Follow up with your health care team and registered dietitian regularly to help you meet your goals.

Cancer treatment may cause eating problems that continue after treatment is complete. Side effects like being too tired or not wanting to eat are normal and often pass with time. The good news is that a healthy diet can help to manage these side effects. Below, you will find tips to help with common eating problems that can continue after cancer treatment.

Think of your body like a nice, clean, white shirt. You would use the right detergent to clean and protect the shirt from damage. Just like the white shirt, we should keep our bodies clean with the right kind of food. You can do this by eating plenty of foods rich in antioxidants and phytonutrients, which help clean and protect the cells in your body from damage. An easy way to include phytonutrients in your diet is to look for colorful plant foods like fruits and vegetables.

This helpful chart includes common foods that provide phytonutrients for cancer prevention. Consider the different colors as a tip to which foods are best. You can get the recipes listed using the button below. You can aim to “eat the rainbow.”
