# Nutrition for mesothelioma
General framework
In mesothelioma, nutrition plays a supportive role. There is no proven diet that can cure or stop the disease itself, but good nutritional support can help with energy levels, resilience during treatment, and overall well-being. Because mesothelioma is often accompanied by pain, fatigue, and sometimes problems with eating and swallowing, personalized nutrition can contribute to quality of life.
Most research on nutrition in mesothelioma focuses on general cancer care. Ask your treating physician or dietitian about adapted dietary choices that suit your situation.
Protein needs and muscle maintenance

Patients with mesothelioma often experience weight loss and muscle wasting, especially from the disease itself and from treatments such as chemotherapy. Adequate protein intake helps preserve muscles as much as possible and makes the body more resistant to infections.
This can mean: including fish, meat, eggs, dairy products, legumes and nuts regularly in meals. In case of swallowing or eating disorders, liquid proteins or adapted nutrition may be an option. A dietitian can help you find the right supply for your situation.
Anti-inflammatory nutrients

Research suggests that certain food components — such as omega-3 fatty acids (in fish and seeds), vitamins C and E, and polyphenols (in vegetables, fruit and herbs) — can dampen inflammatory processes in the body. In cancer, this can work supportively.
This is not a replacement for treatment, but healthy choices around vegetables, fruit, whole grains and fatty fish are part of generally beneficial nutrition. A dietitian can help you incorporate these into your eating pattern.
Microbiome and immune function

Recent research points to links between gut bacteria, diet and immune function in cancer patients. A diverse microbiome — stimulated by nutrition high in fiber (vegetables, fruit, whole grains, legumes) — may be relevant for immune response.
This topic is still under investigation. There is no standard "microbiome diet" for mesothelioma. General advice does apply: regular vegetables, fruit and whole grains offer benefits. Discuss this with your treating physician.
Antioxidants and supplements
UnproveniNo scientific evidence that it works
Many cancer patients consider vitamin supplements or herbal preparations. For mesothelioma, there is no evidence that extra antioxidants or supplements affect the disease or improve treatment. Some supplements can even interfere with certain cancer medications.
Do not take supplements without consulting your physician or dietitian. Better sources of vitamins and minerals are food itself: fresh fruit, vegetables, nuts and dairy products.
Interaction between nutrition and treatment

Nutrition can work with or hinder chemotherapy and immunotherapy:
- With chemotherapy: taste changes, nausea and loss of appetite are common. Small, regular meals, adequate fluids and sometimes adapted textures help.
- With immunotherapy: it is unknown whether certain dietary patterns affect the efficacy of immune inhibitors. Caution applies to large supplement intakes or drastic dietary changes during treatment.
Always inform your team what you eat or supplement.
Weight loss and eating problems

Mesothelioma and its treatment often cause:
- Reduced appetite
- Fatigue that makes cooking difficult
- Swallowing or claw disorders (especially with abdominal mesothelioma)
- Nausea and vomiting
Practical steps:
- Eat and drink regularly, even in small amounts
- Choose energy- and protein-rich food (milk, yoghurt, eggs, fish)
- Fortified nutritional drinks can help
- Soft food or liquid forms sometimes necessary
- Ensure adequate fluids
A dietitian or speech-language pathologist can suggest adapted strategies for your specific situation.
Salt, fluids and kidney function

In abdominal mesothelioma, fluid accumulation sometimes occurs. Depending on your situation, your physician may recommend adjustment of salt intake or fluid balance. This is highly individual.
Do not make changes to salt or fluid intake on your own — always consult your healthcare provider.
Quality of life and eating pleasure

Food is not only fuel; it is also part of wellbeing and social contact. For patients with an incurable disease, this can be especially important. Eat what you enjoy, share meals where you can, and do not feel guilty about food choices that give you energy.
Cancer and its treatment are already enough limitations. Food does not need to be one of them, as long as it poses no direct danger to your health.
Frequently asked questions
**Can food stop or cure mesothelioma?**
No. Food cannot stop or reverse the disease process. However, it can contribute to your resilience, energy level, and how you feel. Think of it as support, not as treatment.
**Should I avoid certain foods?**
There is no universal "forbidden list" for mesothelioma. What causes problems varies from person to person (especially around taste and stomach). Work with your dietitian or doctor on what works for you. Avoid making major changes or taking supplements without consultation.
**Do vitamin supplements help with fatigue?**
Extra vitamins usually do not make fatigue disappear. Fatigue in mesothelioma is linked to the disease itself and treatments, not primarily to nutritional deficiency. Regular eating (even in small portions), adequate fluids, and sleep help more. Always discuss supplements with your doctor.
**Can food strengthen immunotherapy?**
Research is being done on this. There is no proven diet to make immunotherapy more powerful. However, it is known that a nourishing eating pattern — vegetables, fruit, whole grains, proteins — is generally beneficial for immune function. Keep your doctor informed of major dietary changes.
