Which 3 Foods to Avoid for Peritoneal Mesothelioma?

Mar 18, 2021

Highlights

No two cancers are the same and neither should your nutrition be. The most commonly asked question to dieticians and oncologists globally is “What Should I Eat?”. The answer is “It Depends”. It depends on the type of cancer, current treatment and supplements being taken, age, gender, BMI, lifestyle and any genetic information available. In short – the answer to “What Should I Eat” for Peritoneal Mesothelioma needs to be personalized to minimize adverse interactions between nutrition (from foods/diet) and treatment, and to improve symptoms.

Foods like Olive and Sweet Potato should be eaten when undergoing Radiation treatment for Peritoneal Mesothelioma. On the same lines, foods like Beetroot and Barley should be avoided with treatment of Radiation for this cancer.

Black Seed supports the Radiation treatment for Peritoneal Mesothelioma. Hence Black Seed may be taken with Radiation treatment for this cancer.

You get the point – your nutrition needs to be personalized and it needs to be re-evaluated as soon as any of the conditions change. Create and follow a nutrition plan personalized to you to minimize adverse interactions of nutrition for cancers like Peritoneal Mesothelioma.



What is Peritoneal Mesothelioma?

Peritoneal Mesothelioma is a rare cancer that develops in the lining of the abdomen called peritoneum. The incidence rate of this cancer is only 1.49 per 1 lakh people per year. This cancer is commonly diagnosed in people who are over 65 years of age, however, it can occur in people of any age. It is commonly found in men as compared to women.

Peritoneal Mesothelioma - Symptoms, Treatment, Diet, Foods

Peritoneal Mesothelioma has prevalence of certain genetic changes. Some of the genes such as BAP1, CUX1, NF2, and TP53 are known to have genetic abnormalities in this cancer resulting in a change of function. 

The genetic abnormalities found in Peritoneal Mesothelioma can influence specific biochemical pathways to drive these cancer cells to aggressive growth and survive the ongoing treatment.  In addition, lifestyle conditions or habits like smoking, alcohol consumption and BMI (Body Mass Index) can have a big influence on the response to your physician prescribed treatments for Peritoneal Mesothelioma. Numerous studies have consistently shown that your nutrition/diet – both food and nutritional supplements can adversely affect the treatment or be supportive or play no role. Hence, the triangulation of Peritoneal Mesothelioma genomics, planned or ongoing therapies and lifestyle need to be thoroughly considered to make decisions on what foods and supplements to consider and avoid while designing diet/nutrition plan. Also, it is important to note that when any of these conditions change, like treatment or lifestyle or cancer diagnosis – it may impact the nutrition and the nutrition/diet plan for Peritoneal Mesothelioma nutrition may have to be redesigned.

Why Eating Right Matters for Peritoneal Mesothelioma?

In Peritoneal Mesothelioma, activation or inhibition of some of the biochemical pathways including DNA Repair, TGFB Signaling, Cell Cycle, PI3K-AKT-MTOR Signaling, C-type Lectin Receptor Signaling, RAS-RAF Signaling, HIPPO Signaling and NFKB Signaling plays an important role in driving the disease. All foods and nutritional supplements contain active ingredients which have a specific molecular action on different biochemical pathways. Hence, while the intake of certain foods and nutritional supplements as part of the diet may support a specific treatment of Peritoneal Mesothelioma, eating few other foods and supplements may lead to adverse interactions with the treatment or may increase the cancer progression.

Example Foods to “Not Eat” and Eat with Radiation treatment for Peritoneal Mesothelioma

The nutrition for cancer always depends on the type of cancer, treatments and supplements being taken (if any), age, gender, BMI, lifestyle and any genetic information available. Here we show changes in nutrition/diet for Peritoneal Mesothelioma considering only the treatment changes.

Foods to Avoid

Beetroot and Barley : Beetroot and Barley contains active ingredients such as Linoleic Acid, Folic Acid, and others. Linoleic Acid interferes with the impact of Radiation in Peritoneal Mesothelioma by activating a specific biochemical pathway called PI3K-AKT-MTOR. Hence, do not eat Beetroot and Barley with Radiation treatment for this cancer. (Nathalia Serna-Marquez et al, Med Oncol., 2017; Mary E Hesdorffer, Am J Clin Oncol., 2008; Saoirse O Dolly et al, ESMO Open., 2017; Chih-Chia Yu et al, Oncotarget., 2017; Daniel R Gomez et al, J Thorac Oncol., 2019)

Foods to Eat

Olive :  Olive contains active ingredients like Acteoside, Lupeol, Quercetin. Intake of Acteoside along with Radiation treatment for Peritoneal Mesothelioma causes a decrease  in a specific biochemical pathway which is called  PI3K-AKT-MTOR Signaling, and this is a very positive effect.  Olive hence should be eaten with Radiation treatment for this cancer. (Yasmeen M Attia et al, Sci Rep., 2018; Olga C J Schuurbiers et al, J Thorac Oncol., 2009; Daniel R Gomez et al, J Thorac Oncol., 2019)

Sweet Potato :  Sweet Potato contains active ingredients like Beta-sitosterol, Quercetin, Citric Acid. Intake of Beta-sitosterol along with Radiation treatment for Peritoneal Mesothelioma causes a decrease in a specific biochemical pathway which is called  DNA Repair, and this is a very positive effect. Sweet Potato hence should be eaten with Radiation treatment for Peritoneal Mesothelioma. (Ramalingam Sharmila et al, Pharmacogn Mag., Jan-Mar 2017; Ilaria Fuso Nerini et al, Cancer Treat Rev., 2020; Julian Biau et al, Front Oncol., 2019; Di Ma; Daniel R Gomez et al, J Thorac Oncol., 2019)

Should I take this Nutritional Supplement for Peritoneal Mesothelioma?

Black Seed : Black Seed contains active ingredients like Thymoquinone, Carvacrol and thymol with no known reported CYP (drug metabolizing enzyme) interactions with Radiation treatment. Black Seed supports the Radiation treatment for Peritoneal Mesothelioma by decreasing the biochemical pathways like NFKB Signaling, PI3K-AKT-MTOR Signaling, Cell Cycle, DNA Repair, TGFB Signaling, C-type Lectin Receptor Signaling and RAS-RAF Signaling. (Yun Luo et al, Oxid Med Cell Longev., 2016; Esfandiar Heidarian et al, Int J Prev Med., 2019; Yun Luo et al, Oxid Med Cell Longev., 2016; Daniel R Gomez et al, J Thorac Oncol., 2019)

What are the Symptoms of Peritoneal Mesothelioma?

In the initial stages, most cancers including Peritoneal Mesothelioma may not cause any signs or symptoms. However, as the disease progresses, Peritoneal Mesothelioma may start showing symptoms. 

Following are some of the signs and symptoms that may be caused by Peritoneal Mesothelioma.

  • Abdominal pain
  • Abdominal swelling
  • Night sweats
  • Fatigue
  • Nausea
  • Diarrhea
  • Unexplained weight loss

Though many of these symptoms may also be caused by various other health conditions, consult your doctor if you experience these symptoms to rule out the possible chances of Peritoneal Mesothelioma.

What are the Treatment Options for Peritoneal Mesothelioma?

The treatment for Peritoneal Mesothelioma may be decided based on different factors including the stage and extent of spread of the cancer, cancer characteristics, symptoms, patient’s general health and medical history, whether the cancer can be removed completely by surgery and whether the cancer was just diagnosed or had come back. The treatment options for Peritoneal Mesothelioma include:

  • Surgery
  • Chemotherapy
  • Radiotherapy
  • Immunotherapy
  • Targeted Therapy

As part of the diet, avoid including those foods and supplements that may adversely interact with the treatments for Peritoneal Mesothelioma.

In Conclusion

The two most important things to remember are that cancer treatments and nutrition are never the same for everyone. Nutrition/diet which includes food and nutritional supplements is an effective tool which is controlled by you, while facing cancer such as Peritoneal Mesothelioma.

“What should I eat?” is the most frequently asked question to cancer dieticians and physicians. The right answer depends upon cancer type, underlying genomics, current treatments, any allergies, lifestyle information, and factors like BMI.

The addon personalized nutrition plan keeps you safe from adverse nutrition interactions.
