Do Mushrooms and Pumpkin Help or Hinder Cancer Treatment?

Is mushroom pumpkin effective against cancer?

Dear Dr.
Yan,
I have been troubled by the differing views on the medicinal effects of certain foods between traditional Chinese medicine and Western medicine, and I hope you can clarify this for me:
1.
According to traditional Chinese medicine practitioners, cancer patients should avoid foods that may produce phlegm or cause internal heat, such as bamboo shoots, mangoes, mushrooms, cilantro, pumpkins, shrimp, crabs, hairtail fish, eel, sea eel, carp, crucian carp, dog meat, rooster, and lamb, to prevent recurrence or worsening of the condition.
2.
However, Western medicine suggests that mushrooms contain a significant amount of active polysaccharide proteins, which can enhance the immune cells in the body and promote the production of interferons and interleukins.
Numerous scientific studies indicate that mushrooms have strong medicinal effects against cancer.
Additionally, pumpkins contain an enzyme that can break down nitrosamines, thereby eliminating their carcinogenic effects.
The carotenoids found in pumpkins can be converted into vitamin A in the liver, which has cancer-preventive properties.
3.
My question is: Should cancer patients avoid the foods mentioned in point 1? Do mushrooms and pumpkins prevent cancer or hinder cancer treatment?

Dr. Yan Sumei reply Traditional Chinese Medicine

Your question highlights a challenge in integrating traditional Chinese and Western medicine.
Indeed, both have their perspectives.
What can be done? One approach is to seek alternative foods that avoid potential harms while capturing the benefits of both.

(1) Pumpkin contains a component that can eliminate the carcinogenic effects of nitrosamines.
Similarly, garlic contains allicin and ajoene, which can serve the same purpose.
Other foods such as green sprouts, soybeans, and sweet oranges also contain phenolic acids that can mitigate the carcinogenic effects of nitrosamines.

(2) The carotenoids found in pumpkin are also present in dark vegetables and yellow fruits, such as broccoli, papaya, tomatoes, red bell peppers, pink grapefruit, sweet potatoes, cantaloupe, and spinach.

(3) Regarding immune system enhancement:
(A) Foods rich in vitamin A or carotenoids act as immune boosters, helping the body produce T-lymphocytes to enhance resistance against foreign infections.

(B) Vitamin C is also known for its immune-boosting properties and is particularly effective against filterable viruses, making it ideal for preventing colds.

(C) Vitamin E can increase the activity of white blood cells and enhance the production of interleukin-2, promoting T-cell production to help the body resist infections.
Older adults, who often have weaker immune systems, should particularly increase their intake of vitamin E, which is abundant in wheat germ, brown rice, oats, and nuts.

(4) Effective components in foods that can resist carcinogenesis include vitamins C and E, carotenoids, zinc, manganese, and glutathione.
Consuming these in appropriate amounts can help achieve health benefits.
Thank you for your inquiry, and best wishes for your health.

When it comes to the dietary considerations for cancer patients, there is often a divergence between traditional Chinese medicine (TCM) and Western medicine perspectives. Your inquiry about the effects of mushrooms and pumpkin on cancer treatment is particularly relevant, as these foods are often viewed differently in various medical paradigms.

1. Mushrooms: From a Western medical standpoint, mushrooms are considered beneficial for cancer patients. They contain polysaccharides, which are known to enhance the immune system. Specific types of mushrooms, such as shiitake, maitake, and reishi, have been studied for their potential anti-cancer properties. Research has shown that these mushrooms can stimulate the production of immune cells, such as interferon and interleukin, which play crucial roles in the body’s defense against cancer. Furthermore, mushrooms are rich in antioxidants and other bioactive compounds that may help reduce inflammation and combat oxidative stress, both of which are important in cancer prevention and treatment.

On the other hand, TCM often advises against consuming certain foods that are believed to generate phlegm or heat in the body, which includes mushrooms. This perspective is based on the holistic view of health in TCM, where the balance of bodily energies is crucial. However, it is essential to note that the scientific evidence supporting the anti-cancer properties of mushrooms is substantial, and many oncologists may recommend their inclusion in a balanced diet for cancer patients.

2. Pumpkin: Similar to mushrooms, pumpkin is generally viewed positively in Western medicine. It contains carotenoids, which are antioxidants that can be converted into vitamin A in the body. This conversion is significant because vitamin A is known for its role in maintaining healthy immune function and may have protective effects against certain types of cancer. Additionally, pumpkin contains enzymes that can help break down nitrosamines, compounds that have been linked to cancer development.

In contrast, TCM may categorize pumpkin as a food that could contribute to phlegm production, leading to recommendations against its consumption. However, the nutritional benefits of pumpkin, including its high fiber content and vitamins, suggest that it can be a healthy addition to the diet of cancer patients, particularly when consumed in moderation.

3. Dietary Recommendations: Given the conflicting views, it is crucial for cancer patients to adopt a balanced approach to their diet. Here are some recommendations:
- Consult with Healthcare Providers: It is essential for patients to discuss their dietary choices with their oncologist or a registered dietitian who specializes in oncology. This ensures that any dietary changes align with their treatment plan and overall health status.

- Focus on Nutrient-Dense Foods: Incorporating a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats can provide essential nutrients that support the immune system and overall health. Foods like mushrooms and pumpkin can be included as part of a diverse diet, provided they do not cause any adverse reactions.

- Monitor Individual Reactions: Each patient may respond differently to various foods. Keeping a food diary to track any symptoms or reactions can help identify which foods may be beneficial or detrimental.

- Avoid Processed Foods: It is generally advisable for cancer patients to limit their intake of processed foods, sugars, and unhealthy fats, which can contribute to inflammation and may negatively impact health.

In conclusion, while traditional beliefs may caution against the consumption of mushrooms and pumpkin, the scientific evidence supports their potential benefits in cancer treatment. A personalized approach, guided by healthcare professionals, is essential for optimizing nutrition during cancer therapy.
