Summary

This pilot study tested whether a plant-based whole-foods meal delivery service is practical for multiple myeloma patients receiving an autologous stem cell transplant. The goal was to see if patients would eat the meals and if it could improve gut microbiome diversity, which is often lost during transplant and linked to worse outcomes. The study enrolled 26 patients and measured enrollment rates, sample collection rates, and how well patients tolerated the diet.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: plant-based whole-foods meal delivery service
What this could lead to: If successful, this could show that a plant-based diet is a practical way to support gut health during stem cell transplant for multiple myeloma.
What could go wrong: This is a very small pilot study (26 people) focused on feasibility, not on proving health benefits. It may not show clear results or be generalizable.
