Fiber: A New Myeloma Prevention Approach with Abundant Positive Effects.

Area of Science:

• Oncology
• Nutrition Science
• Immunology

Background:

• Pre-myeloma diseases, including monoclonal gammopathy of undetermined significance and smoldering myeloma, affect a significant patient population.
• Overweight and obesity are common comorbidities in patients with pre-myeloma conditions.
• Understanding the impact of lifestyle interventions on these conditions is crucial for patient management.

Purpose of the Study:

• To evaluate the feasibility and impact of a 12-week high-fiber diet intervention in patients with overweight/obesity and pre-myeloma diseases.
• To assess the effects of the intervention on quality of life, metabolic health, gut microbiome, and immune function.
• To determine the intervention's influence on multiple myeloma disease progression.

Main Methods:

• A cohort of patients with overweight/obesity and pre-myeloma diseases received 12 weeks of high-fiber meals.
• Participants were provided with nutritional counseling and instructed to monitor food intake and weight.
• The study design involved a comprehensive assessment of various health parameters.

Main Results:

• The high-fiber diet intervention was well-tolerated by the study participants.
• Significant improvements were observed in quality of life and metabolic health markers.
• The intervention positively modulated gut microbiome composition and enhanced immune system function.
• Stable or improved multiple myeloma disease trajectories were noted in the patient group.

Conclusions:

• A high-fiber diet intervention is a safe and effective strategy for patients with overweight/obesity and pre-myeloma diseases.
• This dietary approach offers multifaceted benefits, including improved health outcomes and disease management.
• Further research into nutritional strategies for pre-myeloma and multiple myeloma patients is warranted.
