Eating Well: Diet and Nutrition

Cancer and its treatments take a serious toll on your body, and what you eat can improve your strength, rebuild tissue and help you feel better overall. Eating well is particularly important during and after treatments to reinforce your immune system and begin healing at the cellular level.

Cancer survivors should strive for a plant-based diet full of fruits, vegetables and legumes to provide vitamins, minerals, fibers, carotenoids and other beneficial nutrients that help prevent cancer.  

You should also incorporate whole grains and high-fiber foods — including whole-grain breads, cereals, rice, pasta and beans — into your diet. Associated with a lower risk of developing cancer, whole grain foods are made from the entire grain seed (wheat, rice, oats and barley) so they’re higher in fiber, vitamins and minerals than processed grains.  

Cancer survivors should avoid or limit their consumption of saturated fats, processed foods, high-calorie foods, added or refined sugars, and processed or red meat.

A major contributor of fat and cholesterol, processed and red meat are associated with an increased risk of developing cancer. Nitrates, which can lead to cancer, are added to many processed meats. Additionally, cooking meat at high temperatures produces mutagens and carcinogens known to cause cancer.

If you do eat red meat, opt for lean cuts and smaller portions, and prepare meat, poultry and fish by baking, broiling or poaching.

A diet emphasizing vegetables, fruits, whole grains and legumes can reduce your risk of developing cancer.
