Diet to Enhance the Myeloma Gut Microbiome

Below is a diet to enhance the myeloma gut microbiome. You’re about to undergo induction therapy. Or maybe you’ve relapsed, and you are about to undergo your second, third, or fourth round of treatment.

Regardless, research cites the importance of a diverse gut microbiome to enhance the efficacy of treatment while reducing the toxicity of that treatment.

Below is one of the best explanations of diet and gut health I’ve seen. Thank goodness coffee enhances gut health!

The 5 things you NEED to know for better GUT HEALTH with Professor Tim Spector

Below is a 1-week, gut-microbiome–supportive meal plan for a multiple myeloma (MM) patient. It emphasizes fiber diversity, fermented foods, polyphenols, and anti-inflammatory fats, while being gentle, protein-adequate, and treatment-friendly.

Important notes for MM patients

If the patient is neutropenic or immunocompromised, avoid unpasteurized products and raw sprouts; use pasteurized yogurt/kefir and well-washed, cooked vegetables.

Adjust portions and textures for appetite, nausea, mucositis, or renal issues.

Hydration is essential (water, herbal teas).

Core Microbiome Principles Used

Prebiotics: oats, legumes, onions, garlic, leeks, asparagus, bananas
Fermented foods: yogurt, kefir, miso, sauerkraut (pasteurized if needed)
Polyphenols: berries, green tea, olive oil, herbs
Anti-inflammatory fats: olive oil, nuts, seeds, fatty fish
Protein support: fish, poultry, eggs, tofu, legumes (muscle preservation)

I am a long-term MM survivor. Have you ever wondered why MM is “incurable”? Have you ever wondered why board-certified, MM specialist Dr. James Berenson treats MM patients differently but shows much longer average overall survival?

Have you been diagnosed with MM? What stage? What symptoms? Scroll down the page, post a question or a comment if you’d like to learn more about non-conventional MM therapies like supplements, etc.

Hang in there,

The role of the gut microbiota in chemotherapy response, efficacy and toxicity: a systematic review

Abstract

There is growing evidence for the relationship between the gut microbiota and the effect of chemotherapy. Therefore, this systematic review provides an overview of the current evidence on the effects of the gut microbiota on chemotherapy response, efficacy and toxicity in patients with cancer.

PubMed, Web of Science, and EMBASE were searched to collect studies on cancer patients treated with chemotherapy that evaluated tumor response, efficacy, or toxicity, and included microbiome analysis through fecal samples.

A total of 22 studies were included. Bacteria associated with better response in lung tumors were, amongst others, a relatively higher abundance of Streptococcus mutans, Enterococcus casseliflavus, and Bacteroides, while bacteria linked to response in gastrointestinal tumors included, among others, higher relative abundances of Lactobacillaceae, Bacteroides fragilis, and Roseburia faecis.

Distinctive bacterial taxa were associated with clinical therapy, although causality was not proven. Targeting the gut microbiota during chemotherapy is considered to be a promising approach to enhance the response and to prevent toxicity of chemotherapy.
