Experts now believe choices about our diet account for the vast majority of prostate cancer cases. It’s important to evaluate diet choices when it comes to risk of prostate cancer. Scientists have slowly uncovered a list of cancer super foods and supplements to optimize in your diet while also discovering foods and supplements that could actually contribute to cancer risk and aggression.
We do know that improved nutrition reduces risk of heart disease, cancer, diabetes and obesity, and usually improves overall quality of life. It’s estimated that a third of cancer deaths in the United States can be attributed to diet in adults, including diet’s effect on obesity. Additionally, a healthy diet helps to increase energy levels, facilitate recovery and enhance the immune system. According to the World Health Organization, a person with a body mass index (BMI) of 30 or more is considered obese.
Differences in diet and lifestyle may account for the variability of prostate cancer rates in different countries. Good nutrition may help reduce the risk of developing prostate cancer, slow progression of the disease and prevent aggressive disease. In this section, we discuss guidelines for a healthy diet for good prostate health and guidelines for a healthy diet while in treatment for prostate cancer. These tips, however, should never be used as a replacement for treatment.
Maintaining Good Nutrition During and After Treatment
Maintaining a healthy diet can help you prepare for and recover after cancer treatment. It may also help to prevent the prostate cancer from coming back.
Watching your weight may also reduce your risk of dying from prostate cancer. Recent studies have indicated that the risk of dying from prostate cancer is more than double in obese men diagnosed with the disease compared with men of normal weight at the time of diagnosis. Obese men with local or regional disease have been shown to have nearly four times the risk of their cancer spreading beyond the prostate or metastasizing.
Prostate cancer treatment may affect your appetite, eating habits, and weight, but it is important for you to maintain a healthy weight, get essential nutrients, and remain as physically active as possible. If you have difficulty eating due to side effects from treatment, there are ways to make eating more comfortable. Working with a registered dietitian/nutritionist (RDN) can help make sure you are getting the nutrition you need.

Unfortunately it is possible for the side effects of surgery, radiation therapy, and chemotherapy to cause you to lose your appetite, eat less and lose weight. On the other hand, some treatments, such as androgen deprivation therapy may cause weight gain for some men.
Tips for Nutrition During Cancer Treatment
Maintain a healthy weight. For many men, this means avoiding weight loss by getting enough calories on a daily basis. For men who are overweight and are obese, this may mean losing some weight. If you are trying to lose weight, it should be moderate, meaning only about a pound a week.
Get essential nutrients the body needs, such as protein, carbohydrates, fiber, vitamins, minerals, phytonutrients, such as carotenoids, and water. Not only will your body function better, you will feel better.
Be as active as you can, such as taking 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.
If you are struggling to eat enough or are eating too much, nutrition counseling may help you get essential nutrients, such as protein, vitamins, and minerals into your diet and maintain a healthy body weight. Ask your health care team for a referral to a registered dietitian or nutritionist. Dietitians and other members of the health care team work with people to meet their nutritional needs.
Side Effects and Nutrition
Cancer treatment often causes side effects, such as nausea, mouth sores, and taste changes that may make it difficult to eat or drink. Follow these tips to help you get the nutrition you need:
If water tastes unpleasant to you, take in more liquid though items such as soup, tea, milk or milk substitutes such as almond milk, or a sports drink. Or, flavor your water by adding fresh cut fruit.
If food tastes bland, try seasoning it with flavorful spices such as garlic, cayenne, dill, and rosemary.
Eat several small meals throughout the day instead of trying to eat large amounts of food at one time.
Enhance your protein intake with protein from foods such as fish, egg whites, cheese, beans, or high protein smoothies.
Suck on mints, chew on gum, or try fresh citrus fruits if you have a metallic taste in your mouth. Brushing your teeth before eating, using plastic utensils, and cooking in glassware can also help.

If you have mouth sores or a gum infection, use a blender to make vegetables and meats smooth. Try juicing or making smoothies.Some side effects are often treated with medication, so talk with your doctor or another member of your health care team for more information.
Food Safety
People receiving cancer treatment need to be aware of food safety, because some treatments may weaken the immune system and lead to an infection. An infection occurs when harmful bacteria, viruses, or fungi, such as yeast, invade the body and the immune system is not able to destroy them quickly enough. Here are some basic food safety tips to reduce the risk of infection.
Wash your hands before and during the handling and preparing of food.
Wash vegetables and fruit thoroughly before eating them.
Handle and store food appropriately. For example, keep raw meat away from other foods when cooking.
Eat thoroughly cooked foods. For example, do not eat eggs that are not cooked solid, and do not eat raw fish, oysters, or shellfish.
Avoid drinking unpasteurized beverages, such as unpasteurized cider, raw milk, and fruit juices.
Make sure food you purchase is not past its “sell-by” or expiration date.
Nutrition After Cancer
Choosing to eat a diet filled with fresh fruits and vegetables and other unprocessed, low-fat foods will help you regain strength after prostate cancer treatment. Nutritious eating can also reduce the risk of heart disease, high blood pressure, obesity, and diabetes. In addition, recent research suggests that making healthy food choices in your survivorship may lower your risk of recurrence and help you live longer. According to many experts, the types of foods recommended to help prevent prostate cancer are the same ones that protect against prostate cancer recurrence. These experts recommend eating plant-based foods (such as fruits, vegetables, and whole grains), lean protein, and low-fat dairy products, and avoiding highly processed foods and red meats as much as possible.
