Why Are Mesothelioma Nutrition and Diet Plans Important?

Diet and nutrition are vital for patients diagnosed with any type of cancer, including mesothelioma.

Mesothelioma diet and nutrition play important roles in:

  • Energy levels: Mesothelioma cancer treatments like chemotherapy and surgery can sap one’s energy. Eating the right foods gives mesothelioma patients the physical and mental strength to carry out activities.
  • Immune system function: Cancer and the treatments used to manage it can greatly weaken the body’s immune system. Proper mesothelioma nutrition can strengthen the immune system to fight cancer and boost your ability to fend off sickness and infection.
  • Maintaining a healthy weight: Mesothelioma and the treatments for it can result in drastic weight loss. Eating healthily can get you to a proper weight, reducing the chances of complications during and after treatment.
  • Managing treatment side effects: Cancer treatments often cause side effects such as fatigue and nausea. Following your mesothelioma diet can minimize these side effects and improve your quality of life while receiving the treatment you need to become a mesothelioma survivor.

Nutrition Tips for Mesothelioma Patients

Eating healthily before, during, and after treatment can help you stay stronger and feel better.

Here are 7 top mesothelioma nutrition tips:

  1. If you have mouth sores from chemotherapy, stay away from hot foods and drinks, alcoholic beverages, crunchy foods, and anything acidic. You should also cut food into small pieces and cook foods until they are soft and tender so they are easier to chew.
  2. Eat 5-9 servings of fruits and vegetables each day to give your body essential nutrients.
  3. Chemotherapy can cause taste changes. Try bitter, sour, sweet, and salty flavors to make food more appealing.
  4. Nausea is a common side effect of treatment. You can control your nausea by eating dry foods like breadsticks and crackers and eating easy-to-digest foods rather than heavy meals.
  5. Eat room-temperature foods if cooking smells bother you. “Foods and drinks stored at room temperature can decrease nausea and are better tolerated by the digestive system,” says mesothelioma nurse Amy Fair.
  6. Eating at regular intervals throughout the day can help prevent malnutrition and keep you energized.
  7. If you feel bloated, drink small amounts of liquid. Do not skip snacks and meals — an empty stomach may make your nausea worse. You should also rinse your mouth after and before eating.

Foods to Support Mesothelioma Treatment Recovery

Some foods have nutrients that may promote recovery from mesothelioma treatment. However, others can negatively interact with chemotherapy drugs and other mesothelioma treatments. Your oncologist (cancer care doctor) can advise you on what to eat during recovery and refer you to a nutritionist if needed.

Depending on your overall health and treatment plan, your doctor may suggest incorporating the following foods:

  • Fiber-rich foods like potatoes and vegetables can balance insulin levels and potentially reduce mesothelioma cell growth.
  • Herbs and spices such as mint, rosemary, turmeric, and dill may offer anti-inflammatory and immune-boosting benefits.
  • Medicinal teas like moringa leaf and chamomile are rich in antioxidants, which are substances that can protect the body from free radicals. Free radicals attack healthy cells and change their genes, encouraging cancerous tumors to grow.
  • Natural sources of coenzyme Q, which is a nutrient in trout, beef, herring, chicken, soybeans, sardines, peanuts, and lentils that can protect the heart from chemotherapy damage.
  • Omega-3 fatty acids found in fish can reduce inflammation and may also lower the risk of cancer coming back, according to MD Anderson Cancer Center in Houston.

Vitamins, Herbs, and Supplements to Aid Mesothelioma Diets

Mesothelioma patients who experience side effects from cancer treatments may be able to find relief through vitamins, herbs, and supplements. Supplements come in many forms, including gummies, pills, bars, powders, and injections.

Common supplements for mesothelioma patients include:

  • Amino acids
  • Beta-carotene
  • Calcium
  • Magnesium
  • Protein supplements
  • Selenium
  • Vitamins A, B12, D, and E
  • Zinc

Talk to your mesothelioma doctor before taking dietary supplements. Certain supplements can interfere with cancer drugs, reducing their effectiveness and causing negative side effects.

For instance, high levels of vitamin E and C can interfere with radiation therapy. Similarly, garlic, St. John’s wort, and ginseng supplements may make chemotherapy drugs less effective.

How to Make a Meal Plan for Mesothelioma

The best way to follow a nutritious diet for mesothelioma is to meal plan. Follow these steps to get started.

1. Replace Low-Calorie Foods

First, replace low-calorie foods like salads and other vegetables with starchy equivalents like sweet potatoes and potatoes. This will give your body more energy to withstand mesothelioma treatments and fight cancer.

You can also increase your caloric intake by adding the following high-calorie foods to your diet:

  • Avocados
  • Chocolate sauce
  • Cream cheese
  • Drinks such as smoothies, milkshakes, and fruit nectars
  • Soft desserts like ice cream and cake topped with whipped cream

2. Increase Protein Portions of Meals

You should also increase the protein portions of meals and lower your whole grain intake.

Protein helps maintain and build muscle, which is important for mesothelioma patients who may be having problems eating and who are losing weight. It’s especially helpful in the period following surgery.

“A high-protein diet has been known to be effective in helping patients recover after surgery.”
— Amy Fair, RN, Patient Advocate

Add the following to your meals to increase your protein intake:

  • Beans
  • Cheese
  • Chicken
  • Eggs
  • Fish
  • Greek yogurt
  • Lean beef
  • Nut butters
  • Nuts
  • Pork
  • Powdered milk
  • Sliced meats
  • Soy foods such as tempeh and tofu
  • Spinach

3. Reduce Whole Grains

Although whole grains such as cereals are considered a healthy food choice, they can be challenging to digest. They can also worsen certain treatment side effects such as bloating and diarrhea.

Reducing whole grains can also give you more room to eat other nutrient-rich foods, such as vegetables, fruits, and lean meat. These foods provide essential minerals, vitamins, and antioxidants required for immune support and overall health.

4. Watch for Signs of Hypoglycemia (Low Blood Sugar)

In some cases, mesothelioma may cause hypoglycemia, a type of low blood sugar that can be controlled through diet and medication.

Hypoglycemia can cause various side effects, such as:

  • Damp nightclothes and sheets due to sweating
  • Drowsiness
  • Irritability, tiredness, and confusion upon waking
  • Loss of coordination
  • Muscle weakness
  • Nightmares
  • Slurred speech

Early signs and symptoms of hypoglycemia include:

  • Difficulty concentrating
  • Headache
  • Lightheadedness or dizziness
  • Looking pale
  • Nausea or hunger
  • Numbness or tingling of the tongue, lips, or cheek

Tips to Boost a Mesothelioma Patient’s Appetite

Cancer patients often struggle with their appetite and find the thought of food unappealing. They may also struggle with nausea, vomiting, dry mouth, and swallowing problems.

Here are some tips to help stimulate your appetite:

  1. Create a relaxing and cheerful setting by eating with family or friends.
  2. Drink liquids as snacks or after meals, not during or before meals. Liquid can decrease appetite.
  3. Eat 6-8 small meals a day instead of 3 large meals.
  4. Include a larger-than-average portion of protein, such as eggs, poultry, or peanut butter, at each meal.
  5. Juice vegetables and fresh fruits to obtain nutrients without feeling bloated.
  6. Try different flavors and types of food to stimulate your palate.

How Does Treatment Affect Mesothelioma Diet and Nutrition?

Treatment can affect mesothelioma nutrition and diet in various ways. Here’s how mesothelioma chemotherapy, radiation, surgery, and other treatment methods can influence your nutritional and dietary choices.


Chemotherapy affects digestion and chewing because it kills cells in the mouth, digestive tract, and hair follicles. If you develop mouth sores from mesothelioma, you can reduce discomfort by eating lukewarm or cool foods.

Chemotherapy may also change how food tastes, decrease appetite, and cause nausea. Changing your diet or how you eat can help you maintain a healthy body weight and get proper nutrients in spite of these changes. For instance, you can use wooden utensils if food tastes metallic.

Immunotherapy drugs boost the immune system to identify and kill mesothelioma cancer cells more efficiently and effectively. Unfortunately, like chemotherapy drugs, they can also attack normal cells since they remove typical restrictions on immune system cells.

Side effects of immunotherapy drugs can include:

  • Diarrhea
  • Difficult breathing
  • Vision changes
  • Vomiting

If you experience these symptoms, talk to your oncology team. They may be able to prescribe medications to help you feel better and prevent your immune system from attacking healthy cells.

You can also get tips on how to maintain a proper diet while dealing with mesothelioma immunotherapy side effects from your care team.


Mesothelioma radiation therapy in the chest area can affect the way you chew, swallow, or digest food. Similarly, radiation around the abdomen may cause digestive issues, such as bloating, nausea, diarrhea, and vomiting.


If you are underweight, your mesothelioma care team may tell you to gain weight before surgery. Being at a healthy weight going into a mesothelioma surgery can reduce the risk of infection, boost recovery, and improve wound healing.

Some mesothelioma surgeries can make eating difficult. Peritoneal mesothelioma patients may receive nutrition intravenously after abdominal surgery, for example.

Once you can eat, you should eat nutritious meals after surgery to increase energy levels and replenish your blood supply.

Did You Know?

Post-surgery pain medication may cause nausea, decrease appetite, and contribute to constipation. You can reduce constipation by drinking more water and eating more fiber.

How to Avoid Food-Borne Illnesses

Unfortunately, mesothelioma patients are at a higher risk for food-borne illnesses (food poisoning). Their weakened immune systems may not correctly identify and fight parasites, bacteria, and other potentially dangerous organisms in food.

Mesothelioma patients should follow these steps to avoid food-borne illnesses.

1. Stay Away From Undercooked or Raw Foods

Raw or undercooked foods made from animals are the most likely to be contaminated by potentially dangerous organisms. Examples include unpasteurized milk, lightly cooked or raw eggs, undercooked poultry and meat, and raw shellfish.

2. Follow Food Safety Tips

The Centers for Disease Control and Prevention shares these tips for avoiding food-borne illnesses:

  • Wash surfaces and hands often. Wash your hands for at least 20 seconds with soap before eating and after preparing food. You should also wash your cutting boards, utensils, and countertops with hot, soapy water after preparing food.
  • Don’t cross-contaminate. Raw meat, eggs, and seafood can spread germs to cooked food unless you keep them separate. Use one cutting plate or board for raw seafood, eggs, and meat, and another surface for breads, produce, and other foods that are ready to eat.
  • Cook raw meat to the right temperature. Food is safe to eat only when it is cooked to a temperature that is high enough to kill germs. Use a food thermometer to determine whether foods have a safe internal temperature.
  • Refrigerate food promptly. Bacteria can multiply rapidly when food isn’t quickly refrigerated. Keep your refrigerator set at 40°F or below and your freezer at 0°F or below. Additionally, remember to dispose of food before it spoils.

3. Watch for Food Recalls and Disease Outbreaks

Keeping an eye on food-related disease outbreaks and food recalls can also prevent food-borne illnesses. Once you discover that a particular type or brand of food may have problems, you should avoid any consumption or contact with it.

As an example, a recall was issued in February 2024 after the FDA and CDC’s investigation into Listeria monocytogenes infections linked to certain cheeses and dairy products manufactured in California and sold under various brand names. Certain strains of Listeria can cause fever, muscle aches, nausea, tiredness, vomiting, and diarrhea.

Here are other bacteria that can cause food recalls and disease outbreaks:

  • E. coli is a bacteria that can cause mild to severe gastrointestinal illness. It is mostly harmless but certain strains can lead to symptoms like stomach cramps, diarrhea, fever, and vomiting.
  • Salmonella is a bacterial illness that may be caused by eating foods contaminated with animal feces.
  • Scombroid fish poisoning happens when you eat fish contaminated with high histamine levels. Common symptoms include palpitations, rash, flushing, vomiting, sweating, and headaches.

4. Know the Symptoms of Food Poisoning

Last but not least, you should know the symptoms of food poisoning. This will help you get treatment on time and avoid future bouts of food poisoning.

Common food poisoning side effects include the following:

  • Abdominal cramps
  • Appetite loss
  • Dizziness
  • Fatigue
  • Fever
  • Flu-like sickness
  • Muscle pain and aches
  • Nausea
  • Upset stomach
  • Vomiting
  • Weakness

If you think you have food poisoning, monitor your symptoms and seek medical care right away if they become severe.
