All mesothelioma patients can benefit from cancer-fighting foods but not for the reason many people believe.

The idea of foods that fight cancer may conjure up a notion of nutrients killing tumor cells, similarly to the way mesothelioma treatment works.

However, this isn’t how nutrition affects the body. Instead, healthy foods bolster your body’s natural ability to fight cancer. They support immune function and promoting healing and recovery.

This allows you to stay on track with your treatment schedule and medication doses. Getting all of your planned therapy is critical to achieving optimal tumor control.

Cancer-Fighting Foods

Cancer-fighting recipes will help you add the following key foods into your mesothelioma dietary plan.

Proteins: Chicken, Fish, Dairy, Meat, Eggs and More

Protein is among the most important nutrients for a mesothelioma patient. Excellent, protein-rich options include:

  • Chicken
  • Fish
  • Lean beef and pork
  • Greek yogurt
  • Beans, lentils and peas
  • Soy foods
  • Eggs
  • Nuts
  • Cheese

Regardless of your usual body weight — whether you are thin, average or overweight — your body needs extra protein after a mesothelioma diagnosis.

Even if you feel you have “room to spare” and some extra body weight, you should do everything you can to avoid losing weight during treatment.

Maintaining your weight and eating plenty of protein during treatment is the best way to preserve your muscle and support immune cell repair and regeneration. Most cancer patients should aim to eat 0.65 to 0.75 grams of protein per pound of body weight each day.

For example, a person who weighs 175 pounds should try to eat 114 to 131 grams of protein daily.

Yellow, White, Orange and Purple Root Vegetables

Colorful plant foods are among the top cancer-fighting items in the diet. This includes all vegetables, but for people diagnosed with mesothelioma, it’s helpful to focus on the calorie-rich options.

Skip the salads and other low-calorie vegetables. Instead, fuel up with:

  • Purple and white potatoes
  • Orange sweet potatoes and edible pumpkin (not the carving kind)
  • Yellow yams
  • Orange and yellow squash

Many people in mesothelioma treatment struggle to get enough to eat. Good nutrition helps the body weather difficult cancer therapies and fuel recovery. For this reason, focus on the vitamin- and mineral-rich options that also provide energy.

Purple, Red and Blue Fruit

Berries and brightly colored stone fruit are among the most potent cancer-fighting foods in the diet. Those bright colors signal the presence of antioxidants and other cancer-fighting nutrients.

Combining fruit with some protein and fat offers the body calories, vitamins and minerals needed during cancer therapy. These important substances can support healing and recovery during and after mesothelioma treatment.

Try to include the following nutrient-rich fruit — fresh or frozen — in your cancer-fighting food plan:

  • Cherries
  • Blueberries
  • Blackberries
  • Strawberries
  • Raspberries
  • Black raspberries
  • Cranberries
  • Boysenberries
  • Mulberries
  • Red and black currants
  • Salmon berries

Some of these items are only available fresh for a few weeks a year. Frozen fruit retains the same nutrients as fresh, may be less expensive and may be easier to find.

Treat Food Like Medicine

Some people struggle to eat enough during cancer treatment. If this is a problem for you, try to treat food like medication.

You may not feel hungry, but setting a timer to take a few bites or sips of food every hour can help you squeeze more calories and protein into your day. Do this for all of the foods you are able to eat during cancer care.

If you are losing weight after a mesothelioma diagnosis, ask your medical team to refer you to a cancer dietitian. This person can help you design a plan to meet your nutrition needs before, during and after treatment.
