Introduction

MONDAY, Dec. 9, 2024 (HealthDay News) -- New research suggests that individuals at high risk for bone marrow cancer may significantly reduce their chances of developing malignancies by adopting a high-fiber diet.

This groundbreaking study sheds light on the relationship between diet and cancer prevention, particularly for those with a condition known as monoclonal gammopathy of undetermined significance (MGUS), which often precedes multiple myeloma—a prevalent and dangerous blood cancer.

Study Overview

The research involved a small cohort of just 20 patients diagnosed with MGUS, a bone marrow abnormality linked to an elevated risk of developing multiple myeloma.

Over a 12-week period, participants transitioned to a plant-based diet that prioritized high fiber intake, complemented by six months of dietary coaching.

Diet Details

The diet consisted of rich sources of fruits, vegetables, beans, seeds, and whole grains, allowing patients to eat freely as long as they adhered to the guidelines.

Results and Findings

Remarkably, participants shed an average of 8% of their initial body weight during the study.

Not only did they experience weight loss, but they also showed significant improvements in insulin resistance—a key indicator of diabetes—as well as enhancements in their gut microbiome and overall quality of life.

These positive changes were linked to a deceleration in the progression of MGUS.

Significant Outcomes

The implications are striking: two participants who initially showed signs of progression toward cancer saw a notable improvement, with no patients advancing to multiple myeloma within a year following enrollment in the trial.

Expert Insights

The study's lead author, Dr. Urvi Shah, a myeloma specialist at Memorial Sloan Kettering Cancer Center in New York City, emphasized how this research empowers patients with precancerous conditions to make informed dietary changes that could mitigate their cancer risk.

Related Animal Studies

Adding further weight to these findings, previous studies conducted on mice indicated that nearly 44% of myeloma-prone mice fed a high-fiber diet managed to avoid developing the disease, whereas those on a standard diet all eventually did.

Nutrition's Role in Disease Prevention

Dr. Shah noted the importance of nutrition in fighting disease, stating, "This study showcases the power of nutrition—specifically a high-fiber, plant-based diet—and unlocks a better understanding of how it can lead to improvements in the microbiome and metabolism to build a stronger immune system, potentially warding off myeloma."

Future Directions

Given the encouraging results, researchers are gearing up for a larger follow-up study involving 150 MGUS patients.

However, it’s important to note that as these findings were presented at a medical conference, they are considered preliminary until published in a peer-reviewed journal.
